void vtkGPUVolumeRayCastMapper::SetMaskInput ( vtkImageData * mask )

Optionally, set a mask input.

This mask may be a binary mask or a label map. This must be specified via SetMaskType.

If the mask is a binary mask, the volume rendering is confined to regions within the binary mask. The binary mask is assumed to have a datatype of UCHAR and values of 255 (inside) and 0 (outside).

The mask may also be a label map. The label map is allowed to contain only 3 labels (values of 0, 1 and 2) and must have a datatype of UCHAR. In voxels with label value of 0, the color transfer function supplied by component 0 is used. In voxels with label value of 1, the color transfer function supplied by component 1 is used and blended with the transfer function supplied by component 0, with the blending weight being determined by MaskBlendFactor. In voxels with a label value of 2, the color transfer function supplied by component 2 is used and blended with the transfer function supplied by component 0, with the blending weight being determined by MaskBlendFactor.

virtual vtkImageData* vtkGPUVolumeRayCastMapper::GetMaskInput ( )

virtual

Optionally, set a mask input.

This mask may be a binary mask or a label map. This must be specified via SetMaskType.

If the mask is a binary mask, the volume rendering is confined to regions within the binary mask. The binary mask is assumed to have a datatype of UCHAR and values of 255 (inside) and 0 (outside).

The mask may also be a label map. The label map is allowed to contain only 3 labels (values of 0, 1 and 2) and must have a datatype of UCHAR. In voxels with label value of 0, the color transfer function supplied by component 0 is used. In voxels with label value of 1, the color transfer function supplied by component 1 is used and blended with the transfer function supplied by component 0, with the blending weight being determined by MaskBlendFactor. In voxels with a label value of 2, the color transfer function supplied by component 2 is used and blended with the transfer function supplied by component 0, with the blending weight being determined by MaskBlendFactor.

virtual void vtkGPUVolumeRayCastMapper::SetMaskType ( int )

virtual

Set the mask type, if mask is to be used.

See documentation for SetMaskInput(). The default is a LabelMapMaskType.

virtual int vtkGPUVolumeRayCastMapper::GetMaskType ( )

virtual

Set the mask type, if mask is to be used.

See documentation for SetMaskInput(). The default is a LabelMapMaskType.

void vtkGPUVolumeRayCastMapper::SetMaskTypeToBinary ( )

Set the mask type, if mask is to be used.

See documentation for SetMaskInput(). The default is a LabelMapMaskType.

void vtkGPUVolumeRayCastMapper::SetMaskTypeToLabelMap ( )

Set the mask type, if mask is to be used.

See documentation for SetMaskInput(). The default is a LabelMapMaskType.

virtual void vtkGPUVolumeRayCastMapper::SetMaskBlendFactor ( float )

virtual

Tells how much mask color transfer function is used compared to the standard color transfer function when the mask is true.

This is relevant only for the label map mask. 0.0 means only standard color transfer function. 1.0 means only mask color transfer function. The default value is 1.0.

virtual float vtkGPUVolumeRayCastMapper::GetMaskBlendFactor ( )

virtual

Tells how much mask color transfer function is used compared to the standard color transfer function when the mask is true.

This is relevant only for the label map mask. 0.0 means only standard color transfer function. 1.0 means only mask color transfer function. The default value is 1.0.

virtual void vtkGPUVolumeRayCastMapper::SetRenderToImage ( int )

virtual

Enable or disable setting output of volume rendering to be color and depth textures.

By default this is set to 0 (off). It should be noted that it is possible that underlying API specific mapper may not supoport RenderToImage mode.

Warning

This method ignores any other volumes / props in the scene.
This method does not respect the general attributes of the scene i.e. background color, etc. It always produces a color image that has a transparent white background outside the bounds of the volume.
