1 Wang Tiles for Image and Texture Generation Workshop in Computer Graphics Semester A, 2003/4

2 The goal of the project Implement an interactive application for texture design and synthesis Use the paper Wang Tiles for Image and Texture Generation [Cohen et al. 03] as the basis

3 What is texture? Texture is an image with certain properties: Locality: small parts look alike Stochastic: they never look exactly the same

4 Texture synthesis We often need large texture images Want to create them from small samples Just tiling the samples is not good enough:

5 Wang Tiles We want non-periodic tiling Use Wang Tiles!

6 Wang Tiles Tile the plane with Want Tiles Adjacent edges have matching colors

7 Wang Tiles properties If the set of tiles is rich enough theres no periodicity We can fill inside the tiles anything we want Texture Geometric primitives Points to create Poisson distribution

8 Automatic texture synthesis Input texture sampleAutomatically generated set of Wang tiles Synthesized textures using Wang tiling

9 Interactive texture design The user fills in the Wang tiles on her own The system displays the result of the tiling interactively
