Detailed Description

A 3D array over an axis-aligned 3D volume, containing one or more channels.

Basically, this contains a set of VolumeGrids all of which are similar (equal shape and size).

See the VolumeGrid class for more information about the basic subroutines.

Member Function Documentation

void MultiVolumeGrid::GetValue ( const IntTriple &  index,
Vector &  values 
) const

Gets all values at the given cell for all channels.

TODO: make this a little faster by precomputing array offset?

void MultiVolumeGrid::TrilinearInterpolate ( const Vector3 &  pt,
Vector &  values 
) const

Gets all values at the given point.

TODO: make this a little faster by precomputing interpolation parameters?
