Struct CpuMesh 

pub struct CpuMesh {
    pub vertices: Vec<CpuVertex>,
    pub indices_u32: Vec<u32>,
    pub joints0: Option<Vec<[u16; 4]>>,
    pub weights0: Option<Vec<[f32; 4]>>,
    pub primitive_topology: PrimitiveTopology,
    pub index_format: IndexFormat,
}

CPU-side mesh data.

Contract:

• vertices + indices fully define geometry.
• primitive_topology is how indices are interpreted.
• Upload step will pack vertices as tightly as possible into a GPU vertex buffer, and indices into a GPU index buffer.

Fields

vertices: Vec<CpuVertex>

indices_u32: Vec<u32>

joints0: Option<Vec<[u16; 4]>>

Optional skinning data (glTF: JOINTS_0 / WEIGHTS_0).

Contract (when present):

• len == vertices.len()
• joints0[i] corresponds to weights0[i]

weights0: Option<Vec<[f32; 4]>>

primitive_topology: PrimitiveTopology

index_format: IndexFormat
