#57936 (Mesh modeling performance regressions). Notes: Optimizing modifiers is out of the scope. Improve geometry buffer configuration (data layout used by the draw manager). Multi-thread edit-mesh to GPU data uploading. Milestone 3 - opensubdiv Fast mesh OpenSubdiv viewport implementation. Undo optimization: skip mesh conversion for meshes which aren't modified. I'd suggest only to support this if it doesn't add a lot of code-complexity. Note: we may run into diminishing returns with UV layer partial updates for custom-data layers, since only updating a single layer will already give us significant benefits. Support partial updates for custom data layers. UV-tangents (note: need to investigate feasibility). Custom Normals (note: need to investigate feasibility). Support updating only modified geometry when transforming vertex coordinates. For the full bmesh to mesh coversion (uses more complex logic).īenchmark production files, and investigate if the current code has room for improvement, making necessary optimizations. For evaluation mesh (uses simplified logic). Limit updates to: selection data, active element. Draw manager support deformed edit-meshes, so an edit-mesh conversion isn't required when drawing an edit-meshes deformed cage (similar to 2.7x support).Ĭreate API functions for tagging edit-mesh changes. Evaluate production scenes (yet to be defined) to ensure that conversion isn't required for common editing operations. Replace lazy initialization with code that uses the edit-mesh, where practical. Lazily initialize by disabling edit-mesh to mesh conversion in the modifier stack, calling lazy initialization where needed.
