VOLUME RENDERING OF IMAGES WITH MULTIPLE CLASSIFICATIONS

摘要

Processes and systems for computer enabled volume data rendering, and more particularly for volume rendering of multiple classificated volume datasets using an Interpolation-Classification (IC) order are provided. Further, an octree min/max can be used for volume rendering with the multiple classifications and at the same time applying the IC order to visualize the multiple classifications volume rendering.

主权项

1. A computer enabled method of depicting an image, comprising the acts of:
providing a data-set representing an image in three dimensions, wherein the data-set includes a plurality of elements; and applying a plurality of transfer functions to the data set, each defining a correspondence of scalar field value and a correspondent color and opacity, wherein:
each of multiple transfer functions is associated with subset of elements of data for controlling the color and opacity for a corresponding group of pixels,each of the plurality of transfer functions is associated with a correspondent group of pixels via an extended octree structure comprising a bit-field extension with min/max values for each node of the extended octree structure, andeach bit in the bit-field extension represents a presence or absence of at least one pixel of data in correspondent sub-volume associated to the correspondent transfer function.
