Enum gfx::IndexBuffer

    Index32(Buffer<R, u32>),
}

[−] Expand description

Type of index-buffer used in a Slice.

The Auto variant represents a hypothetical index-buffer from 0 to infinity. In other words, all vertices get processed in order. Do note that the Slice' start and end restrictions still apply for this variant. To render every vertex in the VertexBuffer, you would set start to 0, and end to the VertexBuffer's length.

The Index* variants represent an actual Buffer with a list of vertex-indices. The numeric suffix specifies the amount of bits to use per index. Each of these also contains a base-vertex. This is the index of the first vertex in the VertexBuffer. This value will be added to every index in the index-buffer, effectively moving the start of the VertexBuffer to this base-vertex.

Construction & Handling

A IndexBuffer can be constructed using the IntoIndexBuffer trait, from either a slice or a Buffer of integers, using a factory.

An IndexBuffer is exclusively used to create Slices.
