dc.description.abstractThe performance of hardware-based interactive rendering systems is often constrained by polygon fill rates and texture map capacity, rather than polygon count alone. We present a new software texture caching algorithm that optimizes the use of texture memory in current graphics hardware by dynamically allocating more memory to the textures that have the greatest visual importance in the scene. The algorithm employs a resource allocation scheme that decides which resolution to use for each texture in board memory. The allocation scheme estimates the visual importance of textures using a perceptually-based metric that takes into account view point and vertex illumination as well as texture contrast and frequency content. This approach provides high frame rates while maximizing image quality.en_US
