How to build the Assimp installer using Inno Setup
1) Get MS VC 2008 SP1 redist packages for x86 and amd64 and copy 'em right here.
vcredist_x86.exe
vcredist_x64.exe
2) Get D3DCompiler_NN.dll and D3DX9_NN.dll from a) your system32 folder and b) your SysWOW64 folder. Copy all 4 here. Rename the 64 bit files to <originalname>_x64.dll. NN is the D3DX version targeted by your DX SDK. If it is not 42, you need to update the Inno setup script (script.iss) as well. If you don't have a 64 bit Windows, get the DLLs from somebody else. Please don't ask google because many DLL downloads are infected.
3) Build assimp, assimpcmd and assimpview for the 'release-dll' target and both the Win32 and x64 architectures.
4) Get Inno Setup
5) Compile, output is written to the 'out' folder.

Open Asset Import Library (Assimp) SDK Installer
Release Notes
------------------------------------------------------------------------------------
http://assimp.sf.net
Troubleshooting
===============
1. Missing d3dx9_(some-number).dll?
Install the latest DirectX runtime or grab the file from somewhere (that's evil but mostly fine).
2. Application configuration not correct / missing msvcr***.dll?
Reinstall Microsoft Visual C++ 2005 SP1 Redistributable (x86 or x64, depending on your system)
3. assimp.exe not in PATH
Add it to PATH. That's not a bug, the installer does not alter the PATH.
4. Crashes immediately
You CPU lacks SSE2 support. Build Assimp from scratch to suit your CPU, sorry.

Known Bugs & Limitations
========================
Viewer
- Normals appear flipped from time to time when either of the normals-related menu items was hit.
- Alpha-sorting is implemented, but still causes artifacts when models are moved quickly.
- Several important texture file formats (such as GIF) are not supported.
- HUD is blurred on the right side. ATI/AMD hardware only.

Known Bugs & Limitations
========================
Viewer
- For files more than one embedded texture, only the first is loaded.
- Normals appear flipped from time to time when either of the normals-related menu items was hit.
- Alpha-sorting is implemented, but still causes artifacts when models are moved quickly.
- Several important texture file formats (such as GIF) are not supported.
- HUD is blurred on the right side. ATI/AMD hardware only.
Troubleshooting
===============
1. Missing d3dx9_42.dll?
Install the latest DirectX runtime or grab the file from somewhere (that's evil but mostly fine).
2. Application configuration not correct / missing msv*** DLLs?
(Re)install Microsoft Visual C++ 2005 SP1 Redistributable (x86 or x64, depending on your system)
3. Crashes immediately
You CPU lacks SSE2 support. Build Assimp from scratch to suit your CPU, sorry.

Build Asset Importer Lib for Android
====================================
This module provides a facade for the io-stream-access to files behind the android-asset-management within
an Android-native application.
- It is built as a static library
- It requires Android NDK with android API > 9 support.
### Building ###
To use this module please provide following cmake defines:
```
-DASSIMP_ANDROID_JNIIOSYSTEM=ON
-DCMAKE_TOOLCHAIN_FILE=$SOME_PATH/android.toolchain.cmake
```
"SOME_PATH" is a path to your cmake android toolchain script.
### Code ###
A small example how to wrap assimp for Android:
```cpp
#include <assimp/port/AndroidJNI/AndroidJNIIOSystem.h>
Assimp::Importer* importer = new Assimp::Importer();
Assimp::AndroidJNIIOSystem *ioSystem = new Assimp::AndroidJNIIOSystem(app->activity);
if ( nullptr != iosSystem ) {
importer->SetIOHandler(ioSystem);
}
```

This is a set of Delphi units for using the Assimp C DLL. This was created for use with Delphi 7, but should be usable as-is or with minimal modifications with later Delphi versions.
This set of headers is enough to load and display a model with external textures. Since I'm not familiar with animated models and some of the other functionality of the assimp library, I did not convert the headers for those features.
See http://sourceforge.net/tracker/?func=detail&aid=3212646&group_id=226462&atid=1067634 for the original patch

PyAssimp Readme
===============
A simple Python wrapper for Assimp using `ctypes` to access the library.
Requires Python >= 2.6.
Python 3 support is mostly here, but not well tested.
Note that pyassimp is not complete. Many ASSIMP features are missing.
USAGE
-----
### Complete example: 3D viewer
`pyassimp` comes with a simple 3D viewer that shows how to load and display a 3D
model using a shader-based OpenGL pipeline.
![Screenshot](3d_viewer_screenshot.png)
To use it, from within `/port/PyAssimp`:
```console
$ cd scripts
$ python ./3D-viewer <path to your model>
```
You can use this code as starting point in your applications.
### Writing your own code
To get started with `pyassimp`, examine the simpler `sample.py` script in `scripts/`,
which illustrates the basic usage. All Assimp data structures are wrapped using
`ctypes`. All the data+length fields in Assimp's data structures (such as
`aiMesh::mNumVertices`, `aiMesh::mVertices`) are replaced by simple python
lists, so you can call `len()` on them to get their respective size and access
members using `[]`.
For example, to load a file named `hello.3ds` and print the first
vertex of the first mesh, you would do (proper error handling
substituted by assertions ...):
```python
from pyassimp import *
scene = load('hello.3ds')
assert len(scene.meshes)
mesh = scene.meshes[0]
assert len(mesh.vertices)
print(mesh.vertices[0])
# don't forget this one, or you will leak!
release(scene)
```
Another example to list the 'top nodes' in a
scene:
```python
from pyassimp import *
scene = load('hello.3ds')
for c in scene.rootnode.children:
print(str(c))
release(scene)
```
INSTALL
-------
Install `pyassimp` by running:
```console
$ python setup.py install
```
PyAssimp requires a assimp dynamic library (`DLL` on windows,
`.so` on linux, `.dynlib` on macOS) in order to work. The default search directories are:
- the current directory
- on linux additionally: `/usr/lib`, `/usr/local/lib`,
`/usr/lib/x86_64-linux-gnu`
To build that library, refer to the Assimp master `INSTALL`
instructions. To look in more places, edit `./pyassimp/helper.py`.
There's an `additional_dirs` list waiting for your entries.

INSTALL
-------
Install ``pyassimp`` by running:
::
$ python setup.py install
PyAssimp requires a assimp dynamic library (``DLL`` on windows, ``.so``
on linux, ``.dynlib`` on macOS) in order to work. The default search
directories are:
- the current directory
- on linux additionally: ``/usr/lib``, ``/usr/local/lib``,
``/usr/lib/x86_64-linux-gnu``
To build that library, refer to the Assimp master ``INSTALL``
instructions. To look in more places, edit ``./pyassimp/helper.py``.
There's an ``additional_dirs`` list waiting for your entries.

# <li>Ignore all point and line meshes when you process assimp's output<li>
# <ul>

#
# The components to be removed are specified in a separate
# configuration option, <tt>#AI_CONFIG_PP_RVC_FLAGS<tt>. This is quite useful
# if you don't need all parts of the output structure. Vertex colors
# are rarely used today for example... Calling this step to remove unneeded
# data from the pipeline as early as possible results in increased
# performance and a more optimized output data structure.
# This step is also useful if you want to force Assimp to recompute
# normals or tangents. The corresponding steps don't recompute them if
# they're already there (loaded from the source asset). By using this
# step you can make sure they are NOT there.
#
# This flag is a poor one, mainly because its purpose is usually
# misunderstood. Consider the following case: a 3D model has been exported
# from a CAD app, and it has per-face vertex colors. Vertex positions can't be
# shared, thus the #aiProcess_JoinIdenticalVertices step fails to
# optimize the data because of these nasty little vertex colors.
# Most apps don't even process them, so it's all for nothing. By using
# this step, unneeded components are excluded as early as possible
# thus opening more room for internal optimizations.
#
aiProcess_RemoveComponent = 0x10
## <hr>Generates normals for all faces of all meshes.
#
# This is ignored if normals are already there at the time this flag
# is evaluated. Model importers try to load them from the source file, so
# they're usually already there. Face normals are shared between all points
# of a single face, so a single point can have multiple normals, which

# #aiProcess_JoinIdenticalVertices is #senseless# then.
#
# This flag may not be specified together with #aiProcess_GenSmoothNormals.
#
aiProcess_GenNormals = 0x20
## <hr>Generates smooth normals for all vertices in the mesh.

# This is ignored if normals are already there at the time this flag
# is evaluated. Model importers try to load them from the source file, so
# they're usually already there.
#
# This flag may not be specified together with
# #aiProcess_GenNormals. There's a configuration option,
# <tt>#AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE<tt> which allows you to specify
# an angle maximum for the normal smoothing algorithm. Normals exceeding
# this limit are not smoothed, resulting in a 'hard' seam between two faces.
# Using a decent angle here (e.g. 80 degrees) results in very good visual
# appearance.
#
aiProcess_GenSmoothNormals = 0x40
## <hr>Splits large meshes into smaller sub-meshes.
#
# This is quite useful for real-time rendering, where the number of triangles
# which can be maximally processed in a single draw-call is limited
# by the video driverhardware. The maximum vertex buffer is usually limited
# too. Both requirements can be met with this step: you may specify both a
# triangle and vertex limit for a single mesh.
#
# The split limits can (and should!) be set through the
# <tt>#AI_CONFIG_PP_SLM_VERTEX_LIMIT<tt> and <tt>#AI_CONFIG_PP_SLM_TRIANGLE_LIMIT<tt>
# settings. The default values are <tt>#AI_SLM_DEFAULT_MAX_VERTICES<tt> and
# <tt>#AI_SLM_DEFAULT_MAX_TRIANGLES<tt>.
#
# Note that splitting is generally a time-consuming task, but only if there's
# something to split. The use of this step is recommended for most users.
#
aiProcess_SplitLargeMeshes = 0x80
## <hr>Removes the node graph and pre-transforms all vertices with
# the local transformation matrices of their nodes.
#
# The output scene still contains nodes, however there is only a
# root node with children, each one referencing only one mesh,
# and each mesh referencing one material. For rendering, you can
# simply render all meshes in order - you don't need to pay
# attention to local transformations and the node hierarchy.
# Animations are removed during this step.
# This step is intended for applications without a scenegraph.
# The step CAN cause some problems: if e.g. a mesh of the asset
# contains normals and another, using the same material index, does not,
# they will be brought together, but the first meshes's part of
# the normal list is zeroed. However, these artifacts are rare.
# @note The <tt>#AI_CONFIG_PP_PTV_NORMALIZE<tt> configuration property
# can be set to normalize the scene's spatial dimension to the -1...1
# range.
#
aiProcess_PreTransformVertices = 0x100
## <hr>Limits the number of bones simultaneously affecting a single vertex
# to a maximum value.
#
# If any vertex is affected by more than the maximum number of bones, the least
# important vertex weights are removed and the remaining vertex weights are
# renormalized so that the weights still sum up to 1.
# The default bone weight limit is 4 (defined as <tt>#AI_LMW_MAX_WEIGHTS<tt> in
# config.h), but you can use the <tt>#AI_CONFIG_PP_LBW_MAX_WEIGHTS<tt> setting to
# supply your own limit to the post processing step.
#
# If you intend to perform the skinning in hardware, this post processing
# step might be of interest to you.
#
aiProcess_LimitBoneWeights = 0x200
## <hr>Validates the imported scene data structure.
# This makes sure that all indices are valid, all animations and
# bones are linked correctly, all material references are correct .. etc.
#
# It is recommended that you capture Assimp's log output if you use this flag,
# so you can easily find out what's wrong if a file fails the
# validation. The validator is quite strict and will find #all#
# inconsistencies in the data structure... It is recommended that plugin
# developers use it to debug their loaders. There are two types of
# validation failures:
# <ul>
# <li>Error: There's something wrong with the imported data. Further
# postprocessing is not possible and the data is not usable at all.
# The import fails. #Importer::GetErrorString() or #aiGetErrorString()
# carry the error message around.<li>
# <li>Warning: There are some minor issues (e.g. 1000000 animation
# keyframes with the same time), but further postprocessing and use
# of the data structure is still safe. Warning details are written
# to the log file, <tt>#AI_SCENE_FLAGS_VALIDATION_WARNING<tt> is set
# in #aiScene::mFlags<li>
# <ul>
#
# This post-processing step is not time-consuming. Its use is not
# compulsory, but recommended.
#
aiProcess_ValidateDataStructure = 0x400
## <hr>Reorders triangles for better vertex cache locality.
#
# The step tries to improve the ACMR (average post-transform vertex cache
# miss ratio) for all meshes. The implementation runs in O(n) and is
# roughly based on the 'tipsify' algorithm (see <a href="
# http:www.cs.princeton.edugfxpubsSander_2007_%3ETRtipsy.pdf">this
# paper<a>).
#
# If you intend to render huge models in hardware, this step might
# be of interest to you. The <tt>#AI_CONFIG_PP_ICL_PTCACHE_SIZE<tt>config
# setting can be used to fine-tune the cache optimization.
#
aiProcess_ImproveCacheLocality = 0x800
## <hr>Searches for redundantunreferenced materials and removes them.
#
# This is especially useful in combination with the
# #aiProcess_PretransformVertices and #aiProcess_OptimizeMeshes flags.
# Both join small meshes with equal characteristics, but they can't do
# their work if two meshes have different materials. Because several
# material settings are lost during Assimp's import filters,
# (and because many exporters don't check for redundant materials), huge
# models often have materials which are are defined several times with
# exactly the same settings.
#
# Several material settings not contributing to the final appearance of
# a surface are ignored in all comparisons (e.g. the material name).
# So, if you're passing additional information through the
# content pipeline (probably using #magic# material names), don't
# specify this flag. Alternatively take a look at the
# <tt>#AI_CONFIG_PP_RRM_EXCLUDE_LIST<tt> setting.
#
aiProcess_RemoveRedundantMaterials = 0x1000
## <hr>This step tries to determine which meshes have normal vectors
# that are facing inwards and inverts them.
#
# The algorithm is simple but effective:
# the bounding box of all vertices + their normals is compared against
# the volume of the bounding box of all vertices without their normals.
# This works well for most objects, problems might occur with planar
# surfaces. However, the step tries to filter such cases.
# The step inverts all in-facing normals. Generally it is recommended
# to enable this step, although the result is not always correct.
#
aiProcess_FixInfacingNormals = 0x2000
## <hr>This step splits meshes with more than one primitive type in
# homogeneous sub-meshes.
#
# The step is executed after the triangulation step. After the step
# returns, just one bit is set in aiMesh::mPrimitiveTypes. This is
# especially useful for real-time rendering where point and line
# primitives are often ignored or rendered separately.
# You can use the <tt>#AI_CONFIG_PP_SBP_REMOVE<tt> option to specify which
# primitive types you need. This can be used to easily exclude
# lines and points, which are rarely used, from the import.
#
aiProcess_SortByPType = 0x8000
## <hr>This step searches all meshes for degenerate primitives and
# converts them to proper lines or points.
#
# A face is 'degenerate' if one or more of its points are identical.
# To have the degenerate stuff not only detected and collapsed but
# removed, try one of the following procedures:
# <br><b>1.<b> (if you support lines and points for rendering but don't
# want the degenerates)<br>
# <ul>
# <li>Specify the #aiProcess_FindDegenerates flag.
# <li>
# <li>Set the <tt>AI_CONFIG_PP_FD_REMOVE<tt> option to 1. This will
# cause the step to remove degenerate triangles from the import
# as soon as they're detected. They won't pass any further
# pipeline steps.
# <li>
# <ul>
# <br><b>2.<b>(if you don't support lines and points at all)<br>
# <ul>
# <li>Specify the #aiProcess_FindDegenerates flag.
# <li>
# <li>Specify the #aiProcess_SortByPType flag. This moves line and
# point primitives to separate meshes.
# <li>
# <li>Set the <tt>AI_CONFIG_PP_SBP_REMOVE<tt> option to
# @code aiPrimitiveType_POINTS | aiPrimitiveType_LINES
# @endcode to cause SortByPType to reject point
# and line meshes from the scene.
# <li>
# <ul>
# @note Degenerate polygons are not necessarily evil and that's why
# they're not removed by default. There are several file formats which
# don't support lines or points, and some exporters bypass the
# format specification and write them as degenerate triangles instead.
#
aiProcess_FindDegenerates = 0x10000
## <hr>This step searches all meshes for invalid data, such as zeroed
# normal vectors or invalid UV coords and removesfixes them. This is
# intended to get rid of some common exporter errors.
#
# This is especially useful for normals. If they are invalid, and
# the step recognizes this, they will be removed and can later
# be recomputed, i.e. by the #aiProcess_GenSmoothNormals flag.<br>
# The step will also remove meshes that are infinitely small and reduce
# animation tracks consisting of hundreds if redundant keys to a single
# key. The <tt>AI_CONFIG_PP_FID_ANIM_ACCURACY<tt> config property decides
# the accuracy of the check for duplicate animation tracks.
#
aiProcess_FindInvalidData = 0x20000
## <hr>This step converts non-UV mappings (such as spherical or
# cylindrical mapping) to proper texture coordinate channels.
#
# Most applications will support UV mapping only, so you will
# probably want to specify this step in every case. Note that Assimp is not
# always able to match the original mapping implementation of the
# 3D app which produced a model perfectly. It's always better to let the
# modelling app compute the UV channels - 3ds max, Maya, Blender,
# LightWave, and Modo do this for example.
#
# @note If this step is not requested, you'll need to process the
# <tt>#AI_MATKEY_MAPPING<tt> material property in order to display all assets
# properly.
#
aiProcess_GenUVCoords = 0x40000
## <hr>This step applies per-texture UV transformations and bakes
# them into stand-alone vtexture coordinate channels.
#
# UV transformations are specified per-texture - see the
# <tt>#AI_MATKEY_UVTRANSFORM<tt> material key for more information.
# This step processes all textures with
# transformed input UV coordinates and generates a new (pre-transformed) UV channel
# which replaces the old channel. Most applications won't support UV
# transformations, so you will probably want to specify this step.
#
# @note UV transformations are usually implemented in real-time apps by
# transforming texture coordinates at vertex shader stage with a 3x3
# (homogenous) transformation matrix.
#
aiProcess_TransformUVCoords = 0x80000
## <hr>This step searches for duplicate meshes and replaces them
# with references to the first mesh.
#
# This step takes a while, so don't use it if speed is a concern.
# Its main purpose is to workaround the fact that many export
# file formats don't support instanced meshes, so exporters need to
# duplicate meshes. This step removes the duplicates again. Please
# note that Assimp does not currently support per-node material
# assignment to meshes, which means that identical meshes with
# different materials are currently #not# joined, although this is
# planned for future versions.
#
aiProcess_FindInstances = 0x100000
## <hr>A postprocessing step to reduce the number of meshes.
#
# This will, in fact, reduce the number of draw calls.
#
# This is a very effective optimization and is recommended to be used
# together with #aiProcess_OptimizeGraph, if possible. The flag is fully
# compatible with both #aiProcess_SplitLargeMeshes and #aiProcess_SortByPType.
#
aiProcess_OptimizeMeshes = 0x200000
## <hr>A postprocessing step to optimize the scene hierarchy.
#
# Nodes without animations, bones, lights or cameras assigned are
# collapsed and joined.
#
# Node names can be lost during this step. If you use special 'tag nodes'
# to pass additional information through your content pipeline, use the
# <tt>#AI_CONFIG_PP_OG_EXCLUDE_LIST<tt> setting to specify a list of node
# names you want to be kept. Nodes matching one of the names in this list won't
# be touched or modified.
#
# Use this flag with caution. Most simple files will be collapsed to a
# single node, so complex hierarchies are usually completely lost. This is not
# useful for editor environments, but probably a very effective
# optimization if you just want to get the model data, convert it to your
# own format, and render it as fast as possible.
#
# This flag is designed to be used with #aiProcess_OptimizeMeshes for best
# results.
#
# @note 'Crappy' scenes with thousands of extremely small meshes packed
# in deeply nested nodes exist for almost all file formats.
# #aiProcess_OptimizeMeshes in combination with #aiProcess_OptimizeGraph
# usually fixes them all and makes them renderable.
#
aiProcess_OptimizeGraph = 0x400000
## <hr>This step flips all UV coordinates along the y-axis and adjusts
# material settings and bitangents accordingly.
#
# <b>Output UV coordinate system:<b>
# @code
# 0y|0y ---------- 1x|0y
# | |
# | |
# | |
# 0x|1y ---------- 1x|1y

# You'll probably want to consider this flag if you use Direct3D for

# setting and bundles all conversions typically required for D3D-based
# applications.
#
aiProcess_FlipUVs = 0x800000
## <hr>This step adjusts the output face winding order to be CW.

## <hr>This step splits meshes with many bones into sub-meshes so that each
# su-bmesh has fewer or as many bones as a given limit.
#
aiProcess_SplitByBoneCount = 0x2000000
## <hr>This step removes bones losslessly or according to some threshold.
#
# In some cases (i.e. formats that require it) exporters are forced to
# assign dummy bone weights to otherwise static meshes assigned to
# animated meshes. Full, weight-based skinning is expensive while
# animating nodes is extremely cheap, so this step is offered to clean up
# the data in that regard.
#
# Use <tt>#AI_CONFIG_PP_DB_THRESHOLD<tt> to control this.

D bindings for the Assimp library (http://assimp.sf.net).
---
These bindings provide access to Assimp's C API. They were directly created
from the C header files.
You should be able to create sufficient DDoc documentation for the bindings
using your favourite build tool (such as Rebuild). Please refer to the main
(Doxygen-generated) documentation for general topics.
Please note that the bindings have only been tested on 32 bit systems, they have
yet to be adapted for the different size of the integer types in 64 bit builds
of Assimp.

* Helper structure to describe a virtual camera.
*
* Cameras have a representation in the node graph and can be animated.
* An important aspect is that the camera itself is also part of the
* scenegraph. This means, any values such as the look-at vector are not
* absolute, they're <em>relative</em> to the coordinate system defined
* by the node which corresponds to the camera. This allows for camera
* animations. Static cameras parameters like the look-at or up vectors are
* usually specified directly in the class members, but beware, they could
* also be encoded in the node transformation. The following (pseudo)code
* sample shows how to do it.
*
* Examples:
* ---
* // Get the camera matrix for a camera at a specific time
* // if the node hierarchy for the camera does not contain
* // at least one animated node this is a static computation
* get-camera-matrix (node sceneRoot, camera cam) : matrix
* {
* node cnd = find-node-for-camera(cam)
* matrix cmt = identity()
*
* // as usual - get the absolute camera transformation for this frame
* for each node nd in hierarchy from sceneRoot to cnd
* matrix cur
* if (is-animated(nd))
* cur = eval-animation(nd)
* else cur = nd->mTransformation;
* cmt = mult-matrices( cmt, cur )
* end for
*
* // now multiply with the camera's own local transform
* cam = mult-matrices (cam, get-camera-matrix(cmt) )
* }
* ---
*
* Note: Some file formats (such as 3DS, ASE) export a "target point" – the
* point the camera is looking at (it can even be animated). Assimp
* writes the target point as a subnode of the camera's main node, called
* "<camName>.Target". However, this is just additional information; the
* transformation applied to the main camera node already makes the

# assimp for iOS
(deployment target 6.0+, 32/64bit)
Builds assimp libraries for several iOS CPU architectures at once, and outputs a fat binary from the result.
Run the **build.sh** script from the ```./port/iOS/``` directory. See **./build.sh --help** for information about command line options.
```bash
shadeds-Mac:iOS arul$ ./build.sh --help
[!] ./build.sh - assimp iOS build script
- don't build fat library (--no-fat)
- supported architectures(--archs): armv7, armv7s, arm64, i386, x86_64
- supported C++ STD libs.(--stdlib): libc++, libstdc++
```
Example:
```bash
cd ./port/iOS/
./build.sh --stdlib=libc++ --archs="armv7 arm64 i386"
```
Supported architectures/devices:
### Simulator
- i386
- x86_64
### Device
- ~~ARMv6 (dropped after iOS 6.0)~~
- ARMv7
- ARMv7-s
- ARM64
### Building with older iOS SDK versions
The script should work out of the box for the iOS 8.x SDKs and probably newer releases as well.
If you are using SDK version 7.x or older, you need to specify the exact SDK version inside **build.sh**, for example:
```
IOS_SDK_VERSION=7.1
```
### Optimization
By default, no compiler optimizations are specified inside the build script. For an optimized build, add the corresponding flags to the CFLAGS definition inside **build.sh**.

jassimp
-------
Java binding for assimp.
The class model used by jassimp is not a one-to-one mapping of assimps class/
structure model (due to performance considerations). Please read the javadoc
descriptions of AiMesh and AiWrapperProvider.
The jassimp.lwjgl package contains a LWJGL specific wrapper provider and some
application examples using this wrapper
How To Build
------------
I) native library, for example by issuing this command in jassimp-native/src:
$ gcc jassimp.cpp -I/usr/lib/jvm/default/include/ \
-I/usr/lib/jvm/default/include/linux -lassimp -shared -fPIC -o libjassimp.so
libjassimp.so is required at runtime and must be located in java.library.path.
II) Java binding
The java library is built using ant. Executing "ant" in the port/jassimp
directory should be sufficient to build the library including docs. You
still need to build the native library separately, see above
The java build is configured to create java 1.6 classes
Limitations
-----------
Not all data imports have been tested yet, especially the countless texture
parameters. If you find bugs please report them.
jassimp supports most of assimps features. Current limitations are
* only importing scenes is supported. There are some methods that allow a
modification of the returned objects, but these should be considered as
work in progress. Full blown export support is planned for a future release
* no support for mesh animations
* no support for embedded textures
* no support for importer configurations
* some texture related material properties are not exposed via the API but only
accessible by traversing the list of properties. However this limitation is
also present in the c-API ...
License
-------
The license for jassimp is the same as the main Assimp license.

/**
* Helper structure to describe a virtual camera.<p>
*
* Cameras have a representation in the node graph and can be animated.
* An important aspect is that the camera itself is also part of the
* scenegraph. This means, any values such as the look-at vector are not
* *absolute*, they're <b>relative</b> to the coordinate system defined
* by the node which corresponds to the camera. This allows for camera
* animations. For static cameras parameters like the 'look-at' or 'up' vectors
* are usually specified directly in aiCamera, but beware, they could also
* be encoded in the node transformation. The following (pseudo)code sample
* shows how to do it: <p>
* <code><pre>
* // Get the camera matrix for a camera at a specific time
* // if the node hierarchy for the camera does not contain
* // at least one animated node this is a static computation
* get-camera-matrix (node sceneRoot, camera cam) : matrix
* {
* node cnd = find-node-for-camera(cam)
* matrix cmt = identity()
*
* // as usual - get the absolute camera transformation for this frame
* for each node nd in hierarchy from sceneRoot to cnd
* matrix cur
* if (is-animated(nd))
* cur = eval-animation(nd)
* else cur = nd->mTransformation;
* cmt = mult-matrices( cmt, cur )
* end for
*
* // now multiply with the camera's own local transform
* cam = mult-matrices (cam, get-camera-matrix(cmt) )
* }
* </pre></code>
*
* <b>Note:</b> some file formats (such as 3DS, ASE) export a "target point" -
* the point the camera is looking at (it can even be animated). Assimp
* writes the target point as a subnode of the camera's main node,
* called "<camName>.Target". However this is just additional information
* then the transformation tracks of the camera main node make the
* camera already look in the right direction.
