Function meshopt::ffi::meshopt_analyzeOverdraw

pub unsafe extern "C" fn meshopt_analyzeOverdraw(
    indices: *const c_uint, 
    index_count: usize, 
    vertex_positions: *const f32, 
    vertex_count: usize, 
    vertex_positions_stride: usize
) -> meshopt_OverdrawStatistics

Overdraw analyzer Returns overdraw statistics using a software rasterizer Results may not match actual GPU performance

vertex_positions should have float3 position in the first 12 bytes of each vertex - similar to glVertexPointer
