Volume rendering color mapping on polygonal objects for 3-D printing

摘要

Processes and systems for computer enabled volume data rendering, and more particularly for mapping of volume rendering colors upon polygonal model objects applied to computer enabled volume rendering are described. In one example, the mapping or encoding of the color of volume rendering data upon polygonal model objects located inside volumetric data is achieved by assigning the rendering result of voxels near the surface of the polygonal object.

1. A computer enabled method of depicting an image, comprising:
at a device having one or more processors and memory:
providing a volumetric data-set generated from a scan of a 3 dimensional object, wherein the data-set includes a plurality of elements;applying a transfer function to the volumetric data set to generate a color for each of the elements;accumulating the color of the elements using volume rendering in a local region of each vertex of a polygonal object;mapping a color output of the volume rendering to each vertex of the polygonal object interfacing with elements of the volumetric data-set;displaying the mapped color of the polygonal object; andoutputting the mapped color to a 3D printer.
