Function meshopt::optimize::optimize_overdraw_in_place_decoder

pub fn optimize_overdraw_in_place_decoder<T: DecodePosition>(
    indices: &mut [u32], 
    vertices: &[T], 
    threshold: f32
)

Reorders indices to reduce the number of GPU vertex shader invocations and the pixel overdraw.

indices must contain index data that is the result of optimize_vertex_cache (not the original mesh indices!)

threshold indicates how much the overdraw optimizer can degrade vertex cache efficiency (1.05 = up to 5%) to reduce overdraw more efficiently.
