In: Second Eurographics Workshop on Rendering. Proceedings, [Conference or Workshop Item]

Abstract

Texturing methods developed in the past years are well-suited for "solid objects", which possess a well-defined and sharp surface. Therefore, such methods are unadequate for texturing "foggy" volume objects. Here we propose an approach for generating density distribution defining volume objects of any arbitrary shape. Our approach is a modified spectral synthesis method operating on the spectral representations of texture and main body, and generating discrete voxel fields of the desired body shape. For that purpose, the amplitude and/or phase spectra of body and texture are first filtered adequately and then "merged" together. The resulting spectrum is back-transformed to the (Euclidean) voxel space by means of Fourier transform. By this approach one is able to generate continuous and smooth transitions of an amorphous cloud to any desired shape.
