Volume rendering has been widely used in different fields where several rendering algorithms have been developed, such as shear-warp, ray casting or splatting. But independently of the rendering method, transfer functions are usually used for mapping values and other properties of the volume into colors. As an improvement of transfer functions, style transfer functions are being used, where sphere maps extracted from artwork are used instead of plain colors. In this paper, we propose an interactive designer that would allow the user to create styles in an easy way, and shade them with just a color or a texture. In addition, it guarantees a coherent illumination, making it possible to easily use style transfer functions to achieve realistic rendering.
