Volume body renderer
First Claim
1. A method for voxel-encoding a volume dataset comprising a multiplicity of cells, comprising the steps of:
- defining a multiplicity of polyhedral voxels, each polyhedral voxel corresponding to one cell;
storing a representation of each polyhedral voxel, the representation including a face string having a plurality of bits, and a position string having a plurality of bits, each bit of the face string corresponding to one face of the polyhedral voxel and having a value indicating whether the face is to be displayed, the position string having a value indicating a three-dimensional spatial position of the polyhedral voxel; and
rendering the representation of each polyhedral voxel.

Abstract
Irregular volumes within one or more three-dimensional volume datasets are identified and extracted in response to criteria. The processing involves automatically finding a seed voxel or seed cell that meets the criteria and thus belongs to an irregular volume of interest, and then identifying cells related to the seed cell by one or more predetermined relationships that are therefore also to be grouped into that irregular volume. Information, which can be of any suitable type, identifying each such cell as being related to other cells and belonging to an irregular volume is stored in a suitable data structure. The location or similar neighborhood information and other data describing properties or attributes of the identified cell are also stored. Because the irregular volumes are extracted and pre-processed in this manner, operations including rendering them on a display and performing Boolean and arithmetic operations on them can readily be performed.
