Detailed Description

Ray casting performed on the GPU.

vtkGPUVolumeRayCastMapper is a volume mapper that performs ray casting on the GPU using fragment programs.

This mapper supports connections in multiple ports of input 0 (port 0 being the only required connection). It is up to the concrete implementation whether additional inputs will be used during rendering. This class maintains a list of the currently active input ports (Ports) as well as a list of the ports that have been disconnected (RemovedPorts). RemovedPorts is used the the concrete implementation to clean up internal structures.

Set/Get the transfer 2D Y axis array.

FillInputPortInformation()

int vtkGPUVolumeRayCastMapper::FillInputPortInformation ( int  port, vtkInformation *  info  )

overrideprotectedvirtual

Handle inputs.

This mapper provides an interface to support multiple inputs but it is up to the OpenGL implementation use them during rendering. Currently, only VolumeOpenGL2/vtkOpenGLGPUVolumeRayCastMapper makes use of these inputs.

vtkOpenGLGPUVolumeRayCastMapper vtkMultiVolume

Reimplemented from vtkAbstractVolumeMapper.

TransformInput()

void vtkGPUVolumeRayCastMapper::TransformInput ( int  port )

protected

A transformation is applied (translation) to the input.

The resulting data is stored in TransformedInputs. Takes as an argument the port of an input connection.

///TODO Elaborate on why this is an issue, texture coords (?)

Todo:

This is the workaround to deal with GPUVolumeRayCastMapper not able to handle extents starting from non zero values. There is not a easy fix in the GPU volume ray cast mapper hence this fix has been introduced.

ValidateRender()

int vtkGPUVolumeRayCastMapper::ValidateRender ( vtkRenderer *  , vtkVolume *    )

protected

This method is used by the Render() method to validate everything before attempting to render.

This method returns 0 if something is not right - such as missing input, a null renderer or a null volume, no scalars, etc. In some cases it will produce a vtkErrorMacro message, and in others (for example, in the case of cropping planes that define a region with a volume or 0 or less) it will fail silently. If everything is OK, it will return with a value of 1.

ClipCroppingRegionPlanes()

virtual void vtkGPUVolumeRayCastMapper::ClipCroppingRegionPlanes ( )

protectedvirtual

Compute the cropping planes clipped by the bounds of the volume.

The result is put into this->ClippedCroppingRegionPlanes. NOTE: IT WILL BE MOVED UP TO vtkVolumeMapper after bullet proof usage in this mapper. Other subclasses will use the ClippedCroppingRegionsPlanes members instead of CroppingRegionPlanes.
