Voxel Surfaces with Materials

Atomontage Engine features a powerful representation of composites and the pipeline required for manipulating composite geometry. The video shows five clips of tone-mapped ray-traced scene renders and additional clips showing reflection (top left), material composition (top right), material ratios of materials present in voxels (bottom left) and pixel rendering cost (bottom right; logarithmic scale is represented with different colors). Any voxel may contain arbitrary amounts of different materials, so the presence of a given material doesn’t have to be a binary information. This is equivalent to a combination of physical materials in the real world. Different materials can be densely packed in a volume element (a thin sand layer on a rocky surface) or the visual properties of a material can be altered by some physical effect (pigmented material or rust on the surface). The engine provides means to define both surface and volumetric effects based on such material composition. Surface
