Efficient texture synthesis using strict Wang Tiles
2008
Graphical Models
Preserved Fulltext
Because they are precomputed, Wang Tiles are a very efficient way to generate textures on the fly. But matching problems occur within tiles and at the corners of adjacent tiles. ...
Wang Tiles are constructed from four texture samples, arranged so they can always match a choice of other tiles at two edges. ...

Geometry mesh introduces user control into texture synthesis and editing, and brings more variations in the synthesized results. But still two problems related remain in need of better solutions. ...
Compare to Barla's method, our texture mesh synthesis is more efficient due to patch tiling (Ours only takes 3ms). ...
