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
’s 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 Slice
s.
