Open Asset Import Library (assimp)
|
|
========
|
|
|
|
Open Asset Import Library is a Open Source library designed to load various __3d file formats and convert them into a shared, in-memory format__. It supports more than __30 file formats__ for import and a growing selection of file formats for export. Additionally, assimp features various __post processing tools__ to refine the imported data: _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.
|
|
|
|
This is the development trunk of assimp containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from [assimp.sf.net](http://assimp.sf.net) or from *nix package repositories. According to [Travis-CI] (https://travis-ci.org/), the current build status of the trunk is [](https://travis-ci.org/assimp/assimp)
|
|
|
|
[open3mod](https://github.com/acgessler/open3mod) is an Open Source 3D model viewer based off Assimp's import and export abilities.

#### Repository structure ####
|
|
|
|
|
|
Open Asset Import Library is implemented in C++ (but provides both a C and a
|
|
C++ish interface). The directory structure is:
|
|
|
|
/bin Folder for binaries, only used on Windows
|
|
/code Source code
|
|
/contrib Third-party libraries
|
|
/doc Documentation (doxysource and pre-compiled docs)
|
|
/include Public header C and C++ header files
|
|
/lib Static library location for Windows
|
|
/obj Object file location for Windows
|
|
/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
|
|
/workspaces Build enviroments for vc,xcode,... (deprecated,
|
|
CMake has superseeded all legacy build options!)
|
|
|
|
|
|
|
|
### Building ###
|
|
|
|
|
|
Take a look into the `INSTALL` file. Our build system is CMake, if you already used CMake before there is a good chance you know what to do.
|
|
|
|
|
|
### Where to get help ###
|
|
|
|
|
|
For more information, visit [our website](http://assimp.sourceforge.net/). 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 documentation doesn't solve your problems,
|
|
[try our forums at SF.net](http://sourceforge.net/p/assimp/discussion/817654) or ask on
|
|
[StackOverflow](http://stackoverflow.com/questions/tagged/assimp?sort=newest).
|
|
|
|
For development discussions, there is also a mailing list, _assimp-discussions_
|

|
### Contributing ###
|
