Abstract

The University of Central Florida invention is a novel way of generating optical properties within and at the surface of a voxel data structure. The structure is derived from mesh-based 3D models, controlled by standard UV texture mapping, and a combination of texture types for use in additive manufacturing. The purpose of the invention is to alter the makeup of a 3D-printed model to make it more optically accurate to the originally designed photo-realistic 3D model. There are currently no other processes that allow a designer to specify the underlying properties of a voxel system to achieve realistic transfers and bounces of light in a 3D-printed object. This method uses existing production art to characterize voxels for polyjet printed objects; generate complex three-dimensional voxels structures from 2D textures; and generate/create microsurface gloss effects for polyjet printed objects.
