Exploration and extensions of detail maps

摘要

In this thesis, we explore "detail maps", a technique that is a combination of texture compression and texture synthesis. We decompose a given input texture into its high and low frequency components and, at runtime, recombine these components to generate a visually acceptable reconstruction of the original texture. Detail maps use less memory than the original texture, and they can be implemented in either software or graphics hardware. Our specific contributions are: the elimination of seam artifacts; showing how detail maps can be used for texture transfer and volume textures; and demonstrating how to texture very large spatial areas without visible tile repetition, loss of resolution, or large texture memory overhead. Finally, we present preliminary investigations into the quantitative determination of the textures and the corresponding input parameters that are ideal for this technique.
