Fields§

§schema_version: u32

schema 版本。

§source_vertex_count: usize

源顶点数。

§source_triangle_count: usize

§meshlet_count: usize

簇数。

§max_vertices: u32

本次构建采用的簇顶点上限。

§max_triangles: u32

§descriptors: Vec<u32>

簇描述符 [vertexOffset, vertexCount, triangleOffset, triangleCount] × n。

§vertex_remap: Vec<u32>
