public class OpenCLAlgorithmVolumeNormals
extends OpenCLAlgorithmBase

OpenCL Algorithm implementation calculate the volume normals of a 3D image. Two methods for the normal calculation are provided. One reads the ModelImage data and creates OpenCL Buffers for the data. The other method reads the volume data from a shared OpenGL Texture

OpenGL Texture ID containing the volume data.

Constructor Detail

OpenCLAlgorithmVolumeNormals

public OpenCLAlgorithmVolumeNormals(ModelImage srcImg,
                                    ModelImage destImg,
                                    long type)

Create an OpenCL Algorithm for calculating the volume normals. Does not use OpenGL Shared texture.

Parameters:

srcImg - source image

type - OpenCL Platform type, may be CL.CL_DEVICE_TYPE_GPU to specify the GPU or CL.CL_DEVICE_TYPE_CPU to specify the CPU.

Method Detail

finalize

public void finalize()

Prepare this class for destruction.

Overrides:

finalize in class OpenCLAlgorithmBase

runAlgorithm

public void runAlgorithm()

Starts the program.

Specified by:

runAlgorithm in class AlgorithmBase

calcNormals

private void calcNormals()

Calculates the volume normals from the input source ModelImage. Creates the kernels, command queue, and OpenCL buffers. Execute the kernels on the command queue and saves the result into a new ModelImage.
