Variants

IndexBuffer

Fields

buffer: BufferAnySlice<'a>

The buffer.

data_type: IndexType

Type of indices in the buffer.

primitives: PrimitiveType

Type of primitives contained in the vertex source.

A buffer uploaded in video memory.

MultidrawArray

Fields

buffer: BufferAnySlice<'a>

The buffer.

primitives: PrimitiveType

Type of primitives contained in the vertex source.

Use a multidraw indirect buffer without indices.

MultidrawElement

Fields

commands: BufferAnySlice<'a>

The buffer of the commands.

indices: BufferAnySlice<'a>

The buffer of the indices.

data_type: IndexType

Type of indices in the buffer.

primitives: PrimitiveType

Type of primitives contained in the vertex source.

Use a multidraw indirect buffer with indices.

NoIndices

Fields

primitives: PrimitiveType

Type of primitives contained in the vertex source.

Don’t use indices. Assemble primitives by using the order in which the vertices are in the vertices source.
