texture modelling

BTF Roller [file]

This paper describes a simple method for seamless enlargement
of natural bidirectional texture functions (BTF)
that realistically represent appearance of given material
surfaces. The novel texture synthesis method, which we call
the BTF roller, 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 realtime
rendering of any type of static textures.
