Methods of generating energy transmission properties in voxel data structures using texture maps

Abstract

A procedural approach toward optical characterization of subsurface scattering of light to generate a mixture of optically opaque materials and optically transparent materials, with a scattering map projected from the surface toward the center of mass of a model. The resulting voxel slices communicate with an additive manufacturing printer, with the resulting model using a typical CMYK and white mixture, with the addition of transparency keyed to the alpha channel of the voxel slice texture maps, to create an accurate model. The resulting stack of textures have color values for the voxels at the surface that are extrapolated downward to the center of the mass from the surface normal, thereby creating a color and texture spectrum from the surface normal to the center of mass, to more accurately represent color and texture on a printed object.
