## Detailed Description

Mapper to render volumes defined as vtkMultiBlockDataSet.

vtkMultiBlockVolumeMapper renders vtkMultiBlockDataSet instances containing vtkImageData blocks (all of the blocks are expected to be vtkImageData). Bounds containing the full set of blocks are computed so that vtkRenderer can adjust the clipping planes appropriately.

This mapper creates an instance of vtkSmartVolumeMapper per block to which it defers the actual rendering. At render time, blocks (mappers) are sorted back-to-front and each block is rendered independently. It attempts to load all of the blocks at the same time but tries to catch allocation errors in which case it falls back to using a single mapper instance and reloading data for each block.

Jittering is used to alleviate seam artifacts at the block edges due to the discontinuous resolution between blocks. Jittering is enabled by default. Jittering is only supported in GPURenderMode.

## ◆ SetGlobalIlluminationReach()

void vtkMultiBlockVolumeMapper::SetGlobalIlluminationReach | ( | float | val | ) |

This parameter acts as a balance between localness and globalness of shadows.

A value of 0.0 will be faster, but we'll only capture local shadows. A value of 1.0 will be slower, but we'll capture all shadows. The default value is 0.0.

This parameter is only used when the underlying mapper is a vtkGPUVolumeRayCastMapper.

## ◆ SetVolumetricScatteringBlending()

void vtkMultiBlockVolumeMapper::SetVolumetricScatteringBlending | ( | float | val | ) |

This parameter controls the blending between surfacic approximation and volumetric multi-scattering.

It is only considered when Shade is enabled. A value of 0.0 means that no scattered rays will be cast, no volumetric shadows A value of 1.0 means that the shader will smartly blend between the two models A value of 2.0 means that the shader only uses the volumetric scattering model. The blending is not uniform, and is done in the following way: a value in [0, 1] biases the shader to choose between the two models, and a value in [1, 2] forces the shader to use more the volumetric model.

This parameter is only used when the underlying mapper is a vtkGPUVolumeRayCastMapper.
