Abstract
Textures composed of individual discrete elements are found in everything from human-made glass-tilings to forests and tropical coral. Previous work in discrete element texture synthesis has been limited to synthesizing scenes composed of one discrete element texture. We propose an interactive sketch-based system for synthesizing scenes composed of many discrete element textures. Our main idea is an example-palette, where a user can use our sketch-based tools to create and combine discrete element textures before painting them into a scene. Our interactive sketch-based tools use a new and fast region-growing algorithm that iteratively synthesizes new elements derived from the example-palette. We demonstrate the application of our system for building virtual worlds (such as for video games) and sketch-based modeling. We achieve results that are not possible with state-of-the-art techniques.
