folders (./test/models and ./test/models-nonbsd).
FIXES:
- Many Collada bugfixes, improve fault tolerance
- Fix possible crashes in the Obj loader
- Improve the Ogre XML loader
- OpenGL-sample now works with MinGW
- Fix Importer::FindLoader failing on uppercase file extensions
- Fix flawed path handling when locating external files
- Limit the maximum number of vertices, faces, face indices and
weights that Assimp is able to handle. This is to avoid
crashes due to overflowing counters.
- Updated XCode project files
- Further CMAKE build improvements
API CHANGES:
- Add data structures for vertex-based animations (These are not
currently used, however ...)
- Some Assimp::Importer methods are const now.
1.1 (2010-04-17)
This is the list of relevant changes from the 1.0 (r412) release to 1.1 (r700).
FEATURES:
- Vastly improved Collada support
- Add MS3D (Milkshape 3D) support
- Add support for Ogre XML static meshes
- Add experimental COB (TrueSpace) support
- Automatic test suite to quickly locate regressions
- D bindings (`dAssimp`)
- Python 2.n bindings (`PyAssimp`)
- Add basic support for Unicode input files (utf8, utf16 and utf32)
- Add further utilities to the `assimp` tool (xml/binary dumps, quick file stats)
- Switch to a CMAKE-based build system including an install target for unix'es
- Automatic evaluation of subdivision surfaces for some formats.
- Add `Importer::ReadFileFromMemory` and the corresponding C-API `aiReadFileFromMemory`
- Expose further math utilities via the C-API (i.e. `aiMultiplyMatrix4`)
- Move noboost files away from the public include directory
- Many, many bugfixes and improvements in existing loaders and postprocessing steps
- Documentation improved and clarified in many places.
- Add a sample on using Assimp in conjunction with OpenGL
- Distribution/packaging: comfortable SDK installer for Windows
- Distribution/packaging: improved release packages for other architectures
CRITICAL FIXES:
- Resolve problems with clashing heap managers, STL ABIs and runtime libraries (win32)
- Fix automatic detection of file type if no file extension is given
- Improved exception safety and robustness, prevent leaking of exceptions through the C interface
- Fix possible heap corruption due to material properties pulled in incorrectly
- Avoid leaking in certain error scenarios
- Fix 64 bit compatibility problems in some loaders (i.e. MDL)
BREAKING API CHANGES:
- None -
MINOR API BEHAVIOUR CHANGES:
- Change quaternion orientation to suit to the more common convention (-w).
- aiString is utf8 now. Not yet consistent, however.

# How to contribute
If you want to contribute, follow these steps:
- First, create your own clone of assimp.
- When you want to fix a bug or add a new feature, create a branch on your own fork following [these instructions](https://help.github.com/articles/creating-a-pull-request-from-a-fork/).
- Push it to your fork of the repository and open a pull request.
- A pull request will start our continuous integration service, which checks if the build works for Linux and Windows.
It will check for memory leaks, compiler warnings and memory alignment issues. If any of these tests fail, fix it and the tests will be restarted automatically.
- At the end, we will perform a code review and merge your branch to the master branch.

All credit goes to Assimp. This is simply a stripped down version of their original source code
with some minor patches to make it compile properly. The changes are listed below:
* `code/CMakeLists.txt` line 1053, `RT` is intentionally not found because now Archlinux doesn't seem to be shipping it properly?
* `ZipArchiveIOSystem.cpp` is patched thanks to brechtsander's patch. This issue is tracked at [#4334](https://github.com/assimp/assimp/issues/4334).

# This is intended to be run by a custom target in a CMake project like this.
# 0. Compile program with coverage support.
# 1. Clear coverage data. (Recursively delete *.gcda in build dir)
# 2. Run the unit tests.
# 3. Run this script specifying which source files the coverage should be performed on.
#
# This script will then use gcov to generate .gcov files in the directory specified
# via the COV_PATH var. This should probably be the same as your cmake build dir.
#
# It then parses the .gcov files to convert them into the Coveralls JSON format:
# https://coveralls.io/docs/api
#
# Example for running as standalone CMake script from the command line:
# (Note it is important the -P is at the end...)
# $ cmake -DCOV_PATH=$(pwd)
# -DCOVERAGE_SRCS="catcierge_rfid.c;catcierge_timer.c"

# Features:
#
# - Automatically generates symbols and run-time dependencies from the build dependencies
# - Custom copy of source directory via CPACK_DEBIAN_PACKAGE_SOURCE_COPY
# - Simultaneous output of multiple debian source packages for each distribution
# - Can specificy distribution-specific dependencies by suffixing DEPENDS with _${DISTRO_NAME}, for example: CPACK_DEBIAN_PACKAGE_DEPENDS_LUCID, CPACK_COMPONENT_MYCOMP0_DEPENDS_LUCID

# This module locates the developer's image library.

#
# This module sets:
#
# ::
#
# IL_LIBRARIES - the name of the IL library. These include the full path to
# the core DevIL library. This one has to be linked into the
# application.
# ILU_LIBRARIES - the name of the ILU library. Again, the full path. This
# library is for filters and effects, not actual loading. It
# doesn't have to be linked if the functionality it provides
# is not used.
# ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
# library interfaces with OpenGL. It is not strictly needed
# in applications.
# IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
# IL_FOUND - this is set to TRUE if all the above variables were set.
# This will be set to false if ILU or ILUT are not found,
# even if they are not needed. In most systems, if one
# library is found all the others are as well. That's the
# way the DevIL developers release it.
# TODO: Add version support.
# Tested under Linux and Windows (MSVC)

/// Implementing features.
///
/// Limitations.
///
/// 1. When for texture mapping used set of source textures (r, g, b, a) not only one then attribute "tiled" for all set will be true if it true in any of
/// source textures.
/// Example. Triangle use for texture mapping three textures. Two of them has "tiled" set to false and one - set to true. In scene all three textures
/// will be tiled.
///
/// Unsupported features:
/// 1. Node <composite>, formulas in <composite> and <color>. For implementing this feature can be used expression parser "muParser" like in project
/// "amf_tools".
/// 2. Attribute "profile" in node <color>.
/// 3. Curved geometry: <edge>, <normal> and children nodes of them.
/// 4. Attributes: "unit" and "version" in <amf> read but do nothing.
/// 5. <metadata> stored only for root node <amf>.
/// 6. Color averaging of vertices for which <triangle>'s set different colors.
///
/// Supported nodes:
/// General:
/// <amf>; <constellation>; <instance> and children <deltax>, <deltay>, <deltaz>, <rx>, <ry>, <rz>; <metadata>;
///
/// Geometry:
/// <object>; <mesh>; <vertices>; <vertex>; <coordinates> and children <x>, <y>, <z>; <volume>; <triangle> and children <v1>, <v2>, <v3>;
///
/// Material:
/// <color> and children <r>, <g>, <b>, <a>; <texture>; <material>;
/// two variants of texture coordinates:
/// new - <texmap> and children <utex1>, <utex2>, <utex3>, <vtex1>, <vtex2>, <vtex3>

// Minor parts of this file are extracts from blender data structures,
// declared in the ./source/blender/makesdna directory.
// Stuff that is not used by Assimp is commented.
// NOTE
// this file serves as input data to the `./scripts/genblenddna.py`
// script. This script generates the actual binding code to read a
// blender file with a possibly different DNA into our structures.
// Only `struct` declarations are considered and the following
// rules must be obeyed in order for the script to work properly:
//
// * C++ style comments only
//
// * Structures may include the primitive types char, int, short,
// float, double. Signed specifiers are not allowed on
// integers. Enum types are allowed, but they must have been
// defined in this header.
//
// * Structures may aggregate other structures, unless not defined
// in this header.
//
// * Pointers to other structures or primitive types are allowed.
// No references or double pointers or arrays of pointers.
// A pointer to a T is normally written as std::shared_ptr, while a
// pointer to an array of elements is written as boost::
// shared_array. To avoid cyclic pointers, use raw pointers in
// one direction.
//
// * Arrays can have maximally two-dimensions. Any non-pointer
// type can form them.
//
// * Multiple fields can be declare in a single line (i.e `int a,b;`)
// provided they are neither pointers nor arrays.
//
// * One of WARN, FAIL can be appended to the declaration (
// prior to the semicolon to specify the error handling policy if
// this field is missing in the input DNA). If none of those
// is specified the default policy is to substitute a default
// value for the field.
//
// warn if field is missing, substitute default value
