Draw indexed, instanced primitives.
void DrawIndexedInstanced( UINT IndexCountPerInstance, UINT InstanceCount, UINT StartIndexLocation, INT BaseVertexLocation, UINT StartInstanceLocation );
Number of indices read from the index buffer for each instance.
Number of instances to draw.
The location of the first index read by the GPU from the index buffer.
A value added to each index before reading a vertex from the vertex buffer.
A value added to each index before reading per-instance data from a vertex buffer.
A draw API submits work to the rendering pipeline.
Instancing may extend performance by reusing the same geometry to draw multiple objects in a scene. One example of instancing could be to draw the same object with different positions and colors. Instancing requires multiple vertex buffers: at least one for per-vertex data and a second buffer for per-instance data.
