# Objective - Using bincode to deserialize binary into a MeshletMesh is expensive (~77ms for a 5mb file). ## Solution - Write a custom deserializer using bytemuck's Pod types and slice casting. - Total asset load time has gone from ~102ms to ~12ms. - Change some types I never meant to be public to private and other misc cleanup. ## Testing - Ran the meshlet example and added timing spans to the asset loader. --- ## Changelog - Improved `MeshletMesh` loading speed - The `MeshletMesh` disk format has changed, and `MESHLET_MESH_ASSET_VERSION` has been bumped - `MeshletMesh` fields are now private - Renamed `MeshletMeshSaverLoad` to `MeshletMeshSaverLoader` - The `Meshlet`, `MeshletBoundingSpheres`, and `MeshletBoundingSphere` types are now private - Removed `MeshletMeshSaveOrLoadError::SerializationOrDeserialization` - Added `MeshletMeshSaveOrLoadError::WrongFileType` ## Migration Guide - Regenerate your `MeshletMesh` assets, as the disk format has changed, and `MESHLET_MESH_ASSET_VERSION` has been bumped - `MeshletMesh` fields are now private - `MeshletMeshSaverLoad` is now named `MeshletMeshSaverLoader` - The `Meshlet`, `MeshletBoundingSpheres`, and `MeshletBoundingSphere` types are now private - `MeshletMeshSaveOrLoadError::SerializationOrDeserialization` has been removed - Added `MeshletMeshSaveOrLoadError::WrongFileType`, match on this variant if you match on `MeshletMeshSaveOrLoadError` |
