The vertex count would be stored twice (once in GpuMesh.vertex_count field, once in GpuMesh.buffer_info.Indexed.count) With this solution.
Why not define vertex_count() as a method on GpuMesh? This way you inspect the content of buffer_info and return the value of either NonIndex.vertex_count or Indexed.count.

The count stored there is the size of the index buffer, not the amount of vertices in the mesh

The same thing confused me at first. Imo, we should rename Indexed.count to Indexed.index_count or something.

size would be appropriate then

Oh hey, I also needed this for my path tracing stuff. I have basically the same change in my fork lol. Thanks for the PR! |
Objective
Compute the
vertex_countfor indexed meshes as well as non-indexed meshes.I will need this in a future PR based on #8427 that adds a gizmo component that draws the normals of a mesh when attached to an entity (branch).

Solution
Move
vertex_countfield fromGpuBufferInfo::NonIndexedtoGpuMeshMigration Guide
vertex_countis now stored directly onGpuMeshinstead ofGpuBufferInfo::NonIndexed.
