摘要： Shading attributes for scene geometry are predetermined and cached in one or more alternate scene representations. Lighting, shading, geometric, and/or other attributes of the scene may be precalculated and stored for at least one of the scene representations at an appropriate level of detail. Rendering performance is improved generally and for a variety of visual effects by selecting between alternate scene representations during rendering. A renderer selects one or more of the alternate scene representations for each of the samples based on the size of its filter area relative to the feature sizes or other attributes of the alternate scene representations. If two or more alternate scene representations are selected, the sampled values from these scene representations may be blended. The selection of scene representations may vary on a per-sample basis and thus different scene representations may be used for different samples within the same image.
