Modeling Textured Translucent Materials with Lazy Solid Texture Synthesis

TL;DR: A new parallel, spatially deterministic solid texture synthesis algorithm which generates high resolution solid textures on surfaces within seconds, and can interactively synthesize new textures for surfaces that appear when breaking or cutting objects.

Abstract: An algorithm is introduced for rapidly synthesizing solid textures from a set of 2D example images. In contrast to previous techniques, this method restricts synthesis to a subset of the voxels, while enforcing spatial determinism. A major difficulty lies in reducing the dependency chain of neighborhood matching, so that each voxel only depends on a small number of other voxels. The key idea is to synthesize a volume from a set of 3D candidates, each being a triple of interleaved 2D neighborhoods. An efficient algorithm is presented to carefully select in a pre-process only those candidates forming consistent triples. This significantly reduces the search space during subsequent synthesis. The result is a new parallel, spatially deterministic solid texture synthesis algorithm which generates high resolution solid textures on surfaces within seconds. With a GPU implementation, this method can interactively synthesize new textures for surfaces that appear when breaking or cutting objects.
