Abstract
A structure that can be used to efficiently represent a virtual texture is disclosed. In one embodiment, a machine-readable medium has such a structure stored thereon, and includes a predetermined sample texture, and a predetermined global structure upon which the predetermined sample texture is to be overlaid in a predetermined manner. For example, a specific global structure is disclosed that includes a tiling encoding that describes a structure of a tiling, and a random block sequence that describes a predetermined number of random blocks within the sample texture that are to be pasted over the tiling to actualize the virtual texture. In such an instance, the sequence also describes locations where the blocks are to be pasted over the tiling. Also disclosed is that the structure can in some embodiments be utilized in texturing, such as procedural texturing.
