Hardware Instancing in XNA on the XBOX 360

Adam Miles has created a Hardware Instancing sample for the XBOX 360 in XNA. This sample demonstrates how to render one object many times using only a single draw call. Since the XBOX 360 does not support the XNA functions for object instancing, the code has been created using HLSL shaders and some fancy tricks. Typically support for Hardware Instancing is shotty on different machines, however with the XBOX you are guaranteed the code to work on all XBOX systems identically making Hardware Instancing a very viable option. Note that this code is XBOX 360 specific and will not run properly on windows. Just as the Windows Hardware Instancing code does not work on the XBOX 360. However having both available lets you use Hardware Instancing on both systems :)
