# Objective - Another step towards #15558 ## Solution - Instead of allocating a Vec and then having wgpu copy it into a staging buffer, write directly into the staging buffer. - gets rid of another hidden copy, in `pad_to_alignment`. future work: - why is there a gcd implementation in here (and its subpar, use binary_gcd. its in the hot path, run twice for every mesh, every frame i think?) make it better and put it in bevy_math - zero-copy custom mesh api to avoid having to write out a Mesh from a custom rep ## Testing - lighting and many_cubes run fine (and slightly faster. havent benchmarked though) --- ## Showcase - look ma... no copies at least when RenderAssetUsage is GPU only :3 --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: Kristoffer Søholm <k.soeholm@gmail.com> |
