README

To update assimp use the following steps:

• Download or checkout Assimp's source code assimp.org or from GitHub
• In the Assimp directory, create an out/ directory and from there run cmake .. -DCMAKE_BUILD_TYPE=Release, then make -j
• From out/ copy revision.h to the root of the assimp source tree
• From out/ copy include/assimp/config.h to include/assimp/config.h in the root of the assimp source tree
• Open tnt/CMakeLists.txt and update the lists of public headers, private headers and source files. All files present on disk can be listed but to speed up build times you should remove source files related to importers/exporters we do not use
• Make sure to update the list of definitions that start with -DASSIMP_BUILD_NO_ to skip all the importers we do not want to use
• Make sure the definition -DASSIMP_BUILD_NO_EXPORTER is still there to remove all exporters

In addition we recommend to remove the following directories:

• samples/
• test/
• tools/

We do not use these directories and they take up unnecessary space on disk.
