meshletutils: Add experimental meshopt_extractMeshletIndices#1021
Conversation
Given a cluster index buffer (with global vertex references, but limited to 256 unique values), this function produces meshlet indices (unique global vertex references and a micro-index buffer). This is somewhat similar to meshopt_buildMeshletsScan, but more restrictive and much faster on large vertex counts. This was previously implemented in demo/clusterlod.h, but it can be useful in other code and the implementation fits the core library better.
We still need clodLocalIndices so that clusterlod.h header is self-contained, but this function is now simply a meshopt wrapper.
For now we don't plan to use this function anywhere in demo/main.cpp but we do need testing coverage.
Add meshopt_extractMeshletIndices to experimental list.
