This paper presents a method to synthesize solid textures from heterogeneous translucent materials that have a complex pattern and subsurface scattering effect.
A solid texture provides consistent texture throughout the volume, so that it can be used to model the texture on an arbitrary geometry. However, the solid texture synthesis requires a huge amount of time to generate the volume. Moreover, a synthesized solid texture acquires only the color information from an input exemplar. Therefore, it has been difficult to render the appearance of a translucent object realistically without additional appearance data. This paper introduces a new search method to accelerate synthesizing of solid textures. This method decomposes the candidates in an exemplar into several subgroups and searches for the best similar neighborhood in each decomposed subgroup. The proposed method can reduce the total computational time to less than a half, due to the use of a small number of candidates in the subgroup. This paper also applies subsurface scattering effects using the measured scattering data and the shell-based rendering method for realistic rendering of a synthesized solid texture. This rendering method is available due to densely measured data and full volume information.
Experimental results show that this rendering method can produce realistic rendering results for various heterogeneous translucent objects. It can also represent cross-sections of an object realistically without reconstructing the texture and surface geometry.
