66 II Rendering
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-
output-bound due to the use of RGBA half16.
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.
1.4 Conclusion and Future Work
We have presented a good alternative to real-time 2D reflections applied to planar
objects to simulate specular and/or glossy materials. Our approach is fast and
practical ...
