In computer graphics, realistic solid models require texturing which is implemented by generating spatially filtered three-dimensional (3D) noise. In the technique disclosed, one-dimensional (1D) noise tables are first formed. Then plane waves in three space based on these tables are generated. The wave fronts are perturbed using further 1D tables, and the perturbed waves are added to confuse directionality. The use of different 1D tables in the generator of 3D noise prevents visual symmetries in the textures produced.
