This paper describes a generalization of our previously published simple roller method for seamless enlargement of colour textures such as natural bidirectional texture functions (BTF) that realistically represent appearance of given material surfaces. The generalized roller allows automatic detection of major texture periodicity directions which do not need to be aligned with coordinate axes. The roller texture synthesis method is based on the overlapping tiling and subsequent minimum error boundary cut. One or several optimal double toroidal BTF patches are seamlessly repeated during the synthesis step. While the method allows only moderate texture compression it is extremely fast due to complete separation of the analytical step of the algorithm from the texture synthesis part. The method is universal and easily implementable in a graphical hardware for purpose of real-time rendering of any type of static or dynamic textures.

Near-periodic texture synthesis
 Hatka, Martin
This paper describes two methods for seamless enlargement of difficult colour textures containing both regular periodic and stochastic components. Such textures cannot be modelled using neither simple tiling nor using purely stochastic models. The first novel method automatically recognizes and separates periodic and random texture components. Each of this components is subsequently modelled using the coresponding optimal method. Both independently enlarged texture components are combined in the resulting synthetic near regular texture. The second method detects two main direction of periodicity in regular periodic component and generates several double-toroidal tiles of the same general shape, which can seamlesly enlarge given near-periodic texture without visible regularity.

Váleček - rychlá metoda syntézy textur založená na vzorkování
 Haindl, Michal ; Hatka, M.
This paper describes a method for synthesizing natural textures that realistically matches given colour texture appearance. The novel texture synthesis method, which we call the roller, is based on the overlapping tiling and subsequent minimum error boundary cut. An optimal double toroidal patch is seamlessly repeated during the synthesis step. While the method allows only moderate texture compression it is extremely fast and easily implementable in a graphical hardware for purpose of real-time rendering.
