Class CUDAVolume3D

java.lang.Object

edu.stanford.rsl.conrad.volume3d.Volume3D

edu.stanford.rsl.conrad.cuda.CUDAVolume3D

public class CUDAVolume3D
extends Volume3D

CUDAVolume3D models a Volume3D in the CUDA memory. All functions of Volume3D are also available for this class, but directly implemented in CUDA. If an algorithm is implemented and tested using Volume3D, it can easily ported to CUDA by setting the VolumeOperator to CUDAVolumeOperator. The AnisotropicFilterFunction is a nice example on how to use this interface.
