# Building on Linux
You will need to install Qt and LLVM/libclang beforehand. All other packages will automatically be obtained through CPM.
For pre-requisite packages, check [deps.txt](./deps.txt)
ccache is highly recommended.
If your distribution does not provide ReactPhysics3D, you will have to build (and install) it yourself prior to this step
Use the following to generate the build files:
cmake -Bbuild .
> [!NOTE]
> Add -DCMAKE_BUILD_TYPE=Release to produce a release build
Then build the project using:
cmake --build build
The compiled binaries should then be located in `./build/bin/` and should be ready for redistribution without any further work.
If any of the compilation steps fail, or the binaries fail to execute, please create an issue so that this can be corrected.

sphere.obj was made by subdividing a cube, unwrapping it using cube projection, and then using the "To-sphere" tool in Blender to fully smoothen it out.
Make sure you select "shade smooth" before exporting!
Other settings:
Up axis: Y
Forward axis: -Z
The winding order in .obj files is always counter-clockwise, so my script (genmesh.py) uses reversed() to reverse this and homogenous the winding order
across meshes
