Geometry

Until now we created an index and vertex buffer and called the appropriet methods on a pass instance to configure and issue a draw command. This can be grouped in a Geometry instance to offload the geometry related pass composition to that class.

So instead of doing

pass.setIndexBuffer(iBuf)
pass.setVertexBuffer(vBuf)
pass.setPrimitiveType(primitiveType)
pass.drawIndexed(indexCount, instanceCount, indexOffset, baseVertex, instanceOffset)

we can just call

pass.render(geometry)

and can do it repeatedly
