On the PlayStation 3, we generate the reflection texture in the RGBA half16
format. The texture generation costs between 0.10 ms and 0.33 ms, with an
average of 0.17 ms. The mipmap generation costs 0.16 ms. The process is render-

On the Xbox 360 we use the 10-bit float 7e3 format. The texture generation
costs between 0.06 ms and 0.24 ms with an average of 0.1 ms. The mipmap
generation costs 0.09 ms.

objects to simulate specular and/or glossy materials. Our approach is fast and
