Sketch guided solid texturing

Abstract

Compared to 2D textures, solid textures can represent not only the bounding surfaces, but also their interiors. Existing solid texture synthesis methods pay little attention to the generation of conforming textures that capture geometric structures or reflect the artists’ design intentions. In this paper, we propose a novel approach to synthesizing solid textures using 2D exemplars. The generated textures locally agree with a tensor field derived from user sketching curves. We use a deterministic approach and only a small portion of the voxels needs to be synthesized on demand. Correction is fundamental in deterministic texture synthesis. We propose a history windows representation, which is general enough to unifiedly represent various previous correction schemes, and a dual grid scheme based on it to significantly reduce the dependent voxels while still producing high quality results. Experiments demonstrate that our method produces significantly improved solid textures with a small amount of user interaction.
