Abstract
Processes and systems in computer enabled imaging for the mapping of volume rendering colors upon polygonal model objects applied to computer enabled volume rendering by means of mapping or encoding the color of volume rendering data upon polygonal model objects located inside volumetric data. Exemplary processes and systems including assigning the rendering result of voxels at or near the surface of the polygonal object.
Claims13
A computer enabled method of depicting an image, comprising:
- receiving from a computer readable memory a volumetric data-set generated from a scan of a 3 dimensional object, wherein the data-set includes a plurality of elements;
- receiving from a second computer readable memory a transfer function which defines 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, by a processor, red-green-blue color (RGB) result to each vertex of the polygonal object interfacing with the elements of the volumetric data-set;
- displaying the mapped result of the color mapped polygonal object;
- displaying a depiction of the transfer function including a plurality of control points;
- and
- receiving input from a user at each control point to select a value of a parameter for a portion of a projection associated with that control point.

Apparatus for depicting an image, comprising:
- a first computer readable storage which stores a volumetric data-set generated from a scan of a 3 dimensional object, wherein the data-set includes a plurality of elements;
- a second computer readable storage which stores a transfer function which defines a color for each of the elements;
- a processor coupled to the first and second storages and which accumulates the color of the elements using volume rendering in a local region of each vertex of a polygonal object, maps the color of the elements to the vertices of a polygonal object interfacing with the elements of the volumetric data-set, and causes the display of the mapped result of the color mapped polygonal object;
- and
- a graphical user interface for displaying a depiction of the transfer function including a plurality of user manipulatable control points.
