Parameters

Return Value
Type:
BooleanRemarks Returns false if not found.
If the realValue parameter is true, VolumeViz will return the actual voxel value from the full resolution data. Note that this may require a read from disk if full resolution data is not currently in memory. If false, VolumeViz will return the voxel value from the (possibly subsampled) data currently in memory.

---|
To use GPU picking, you must specify realValue = false. |
