Abstract
A method generates a histogram of a volume data set in a rendering pipeline. The volume data set includes a plurality of samples stored in a memory. Each sample is partitioned in parallel into a plurality of field according to a plurality of format registers, there is one format register for each field. Entries of a plurality of tables are indexed in parallel with the plurality of fields, there is one entry indexed in each table by each field. The indexed entries are incremented to accumulate a histogram of the fields of the samples of the volume data set.

A method for generating a histogram of a volume data set in a rendering pipeline, the volume data set including a plurality of samples stored in a memory, comprising the steps of:
- partitioning, in parallel, each sample into a plurality of fields according to a plurality of format registers, there is one format register for each field;
- indexing, in parallel, entries of a plurality of tables with the plurality of fields, there is one entry indexed in each table by each field;
- and
- incrementing the indexed entries to accumulate a histogram of the fields of the samples of the volume data set.
