Function meshopt::ffi::meshopt_spatialSortTriangles

pub unsafe extern "C" fn meshopt_spatialSortTriangles(
    destination: *mut c_uint, 
    indices: *const c_uint, 
    index_count: usize, 
    vertex_positions: *const f32, 
    vertex_count: usize, 
    vertex_positions_stride: usize
)

Experimental: Spatial sorter Reorders triangles for spatial locality, and generates a new index buffer. The resulting index buffer can be used with other functions like optimizeVertexCache.

destination must contain enough space for the resulting index buffer (index_count elements) indices must contain index data that is the result of meshopt_optimizeVertexCache (not the original mesh indices!) vertex_positions should have float3 position in the first 12 bytes of each vertex - similar to glVertexPointer
