Variants

Vertex

Render vertex data directly from the Mesh's buffer.

Index8(Buffer<R, u8>, VertexCount)

The Index* buffer contains a list of indices into the Mesh data, so every vertex attribute does not need to be duplicated, only its position in the Mesh. The base index is added to this index before fetching the vertex from the buffer. For example, when drawing a square, two triangles are needed. Using only Vertex, one would need 6 separate vertices, 3 for each triangle. However, two of the vertices will be identical, wasting space for the duplicated attributes. Instead, the Mesh can store 4 vertices and an Index8 can be used instead.

Index16(Buffer<R, u16>, VertexCount)

As Index8 but with u16 indices

Index32(Buffer<R, u32>, VertexCount)

As Index8 but with u32 indices
