Figure 3.2. Accumulation results (test scene, AA and DoF) for 1024 frames using

various texture formats. From left to right, the quality is (obviously) increasing.

3.3 Multi-frame Rendering Techniques

One motivation for multi-frame sampling is to have better control of the adjust-

ment of the rendering quality, while implementing against older, limited APIs

and conserving as many GPU resources as possible. Even though the techniques

discussed in this section do not always reflect state-of-the-art techniques, they

have been picked to express the required (re)thinking when creating multi-frame

rendering ...
