%description
When a GPU renders triangle meshes, various stages of the GPU pipeline have
to process vertex and index data. The efficiency of these stages depends on
the data you feed to them; this library provides algorithms to help optimize
meshes for these stages, as well as algorithms to reduce the mesh complexity
and storage overhead.
