VertexBuffer::PreScaleMatrix

Syntax

float3x4 VertexBuffer::PreScaleMatrix() const;

Returns the position prescale matrix that is used in conjunction with the geometry in this vertex buffer.

A position prescale matrix is used to unpack the vertex buffer position stream from a compressed vertex format (e.g. U8) back to the correct scale. Packed position data is used to compress the size of a vertex buffer for more efficient rendering.
