Member Data Documentation

FirstInstanceLocation

Uint32 Diligent::DrawAttribs::FirstInstanceLocation = 0

LOCATION (or INDEX, but NOT the byte offset) in the vertex buffer to start reading instance data from.

NumInstances

Uint32 Diligent::DrawAttribs::NumInstances = 1

The number of instances to draw.

If more than one instance is specified, instanced draw call will be performed.

StartVertexLocation

Uint32 Diligent::DrawAttribs::StartVertexLocation = 0

LOCATION (or INDEX, but NOT the byte offset) of the first vertex in the vertex buffer to start reading vertices from.
