-
updateMeshNormals(
engine: EngineContext,
mesh: Mesh,
normals: Float32Array,
vertexOffset?: number,
vertexCount?: number,
sourceVertexOffset?: number,
): voidParameters
- engine: EngineContext
- mesh: Mesh
- normals: Float32Array
- vertexOffset: number = 0
OptionalvertexCount: number- sourceVertexOffset: number = 0
Returns void
Re-upload (part of) a mesh's NORMAL buffer — the twin of
updateMeshPositionsfor dynamically re-generated geometry whose per-vertex normals change (e.g. a swept tube re-fitted each rebuild). No-op if the mesh was created without normals. Zero-allocation GPU upload only.
