Abstract
This document contains additional material for the submission Procedural Isotropic Stochastic Textures by Example.
Additional Results
Figure 1 and figure 2 are extended versions of the corre-sponding figures in the paper. These figures also contain con-text photographs and additional results.
Comparison with the Method of Heeger and Bergen
In the paper we state that the method of Heeger and Bergenand our method achieve a similar synthesis quality. This is il-lustrated in figure 3.
Integration into Production Rendering Software
In the paper we state that our procedural textures can eas-ily be integrated into production rendering software. Thisisillustrated in figure 4, which shows a screenshot of our methodintegrated intoAutodesk Maya.
Implementation as a GPU Shader
In the paper we state that our procedural textures can easilybe implemented as a GPU shader. This is illustrated in figure 5,which shows a screenshot of a procedural texture implementedas a GPU shader.
Histogram Fitting
Figure 6 shows a clearer version of the histogram and thefitted histogram (the splines) of the corresponding figure inthepaper.

Figure 3: A comparison of our method to the method of Heeger and Bergen. Each example shows a photograph of a texture, an image texture synthesized from thephotograph using the method of Heeger and Bergen, and a procedural texture automatically generated from the photograph using our method. The results of bothmethods are similar, but the method of Heeger and Bergen cannot be formulated as a procedural texture.
