# Blender Script that takes a folder of GLB files and processes them into PLY files
# strips textures and vertex colors leaving only vertex pos, vertex norm, index buffer
# 1. merges model into one contiguous mesh
# 2. scales the model to a unit sphere
# 3. centers the origin
# 4. centers the model
