Open Asset Import Library (assimp)
==================================
A library to import and export various 3d-model-formats including scene-post-processing to generate missing render data.

<br>
APIs are provided for C and C++. There are various bindings to other languages (C#, Java, Python, Delphi, D). Assimp also runs on Android and iOS.
Additionally, assimp features various __mesh post processing tools__: normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials and many more.
### Latest Doc's ###
Please check the latest documents at [Asset-Importer-Lib-Doc](https://assimp-docs.readthedocs.io/en/latest/).
### Get involved ###
This is the development repo containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from [Github Assimp Releases](https://github.com/assimp/assimp/releases).
<br>
You find a bug in the docs? Use [Doc-Repo](https://github.com/assimp/assimp-docs).
<br>
Please check our Wiki as well: https://github.com/assimp/assimp/wiki
If you want to check our Model-Database, use the following repo: https://github.com/assimp/assimp-mdb
#### Supported file formats ####
You can find the complete list of supported file-formats [here](https://github.com/assimp/assimp/blob/master/doc/Fileformats.md)
### Building ###
Take a look into the https://github.com/assimp/assimp/blob/master/Build.md file. We are available in vcpkg, and our build system is CMake; if you used CMake before there is a good chance you know what to do.
### Ports ###
* [Android](port/AndroidJNI/README.md)
* [Python](port/PyAssimp/README.md)
* [.NET](https://bitbucket.org/Starnick/assimpnet/src/master/)

* [Rust](https://github.com/jkvargas/russimp)
### Other tools ###
[open3mod](https://github.com/acgessler/open3mod) is a powerful 3D model viewer based on Assimp's import and export abilities.
#### Repository structure ####
Open Asset Import Library is implemented in C++. The directory structure looks like:
/code Source code
/contrib Third-party libraries
/doc Documentation (doxysource and pre-compiled docs)
/include Public header C and C++ header files
/scripts Scripts used to generate the loading code for some formats
/port Ports to other languages and scripts to maintain those.
/test Unit- and regression tests, test suite of models
/tools Tools (old assimp viewer, command line `assimp`)
/samples A small number of samples to illustrate possible
use cases for Assimp
The source code is organized in the following way:
code/Common The base implementation for importers and the infrastructure
code/PostProcessing The post-processing steps
code/AssetLib/<FormatName> Implementation for import and export for the format
### Where to get help ###
For more information, visit [our website](http://assimp.org/). Or check out the `./doc`- folder, which contains the official documentation in HTML format.
(CHMs for Windows are included in some release packages and should be located right here in the root folder).
If the docs don't solve your problem, ask on [StackOverflow with the assimp-tag](http://stackoverflow.com/questions/tagged/assimp?sort=newest). If you think you found a bug, please open an issue on Github.
Open Asset Import Library is a library to load various 3d file formats into a shared, in-memory format. It supports more than __40 file formats__ for import and a growing selection of file formats for export.
And we also have a Gitter-channel:Gitter [![Join the chat at https://gitter.im/assimp/assimp](https://badges.gitter.im/assimp/assimp.svg)](https://gitter.im/assimp/assimp?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)<br>

///
/// 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>;

/// 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.

/// <amf>; <constellation>; <instance> and children <deltax>, <deltay>, <deltaz>, <rx>, <ry>, <rz>; <metadata>;
