impl PrimitiveDescriptor

Source

pub fn get_vertex_info( &self, vertex_index: u32, geometry_slab: &[u32], ) -> VertexInfo

Returns the vertex at the given index and its related values.

These values are often used in shaders, so they are grouped together.

This takes into consideration all skinning matrices.

Source

pub fn get_vertex(&self, vertex_index: u32, slab: &[u32]) -> Vertex
