------------------------------
A regularly-updated copy is available at
http://assimp.sourceforge.net/lib_html/index.html
A CHM file is included in the SVN repos: ./doc/AssimpDoc_Html/AssimpDoc.chm.
To build the doxygen documentation on your own, follow these steps:
a) download & install latest doxygen
b) make sure doxygen is in the executable search path
c) navigate to ./doc
d) and run 'doxygen'
Open the generated HTML (AssimpDoc_Html/index.html) in the browser of your choice.
Windows only: To generate the CHM doc, install 'Microsoft HTML Workshop'
and configure the path to it in the DOXYFILE first.
https://assimp-docs.readthedocs.io/en/latest/
------------------------------
Building Assimp
------------------------------
More detailed build instructions can be found in the documentation,
this section is just for the inpatient among you.
CMake is the preferred build system for Assimp. The minimum required version
is 2.6. If you don't have it yet, downloads for CMake can be found on
http://www.cmake.org/.
For Unix:
1. mkdir build && cd build
2. cmake .. -G 'Unix Makefiles'
3. make -j4
For Windows:
1. Open a command prompt
2. mkdir build
3. cd build
4. cmake ..
5. cmake --build .
For iOS:
Just check the following project, which deploys a compiler toolchain for different iOS-versions: https://github.com/assimp/assimp/tree/master/port/iOS
Just check the build-instaructions which you can find here: https://github.com/assimp/assimp/blob/master/Build.md
