Detailed Description

represents the common properties for rendering a volume.

vtkVolumeProperty is used to represent common properties associated with volume rendering. This includes properties for determining the type of interpolation to use when sampling a volume, the color of a volume, the scalar opacity of a volume, the gradient opacity of a volume, and the shading parameters of a volume.

When the scalar opacity or the gradient opacity of a volume is not set, then the function is defined to be a constant value of 1.0. When a scalar and gradient opacity are both set simultaneously, then the opacity is defined to be the product of the scalar opacity and gradient opacity transfer functions.

Most properties can be set per "component" for volume mappers that support multiple independent components. If you are using 2 component data as LV or 4 component data as RGBV (as specified in the mapper) only the first scalar opacity and gradient opacity transfer functions will be used (and all color functions will be ignored). Omitting the index parameter on the Set/Get methods will access index = 0.

virtual void vtkVolumeProperty::SetIndependentComponents ( int )

virtual

Does the data have independent components, or do some define color only? If IndependentComponents is On (the default) then each component will be independently passed through a lookup table to determine RGBA, shaded.

Some volume Mappers can handle 1 to 4 component unsigned char or unsigned short data (see each mapper header file to determine functionality). If IndependentComponents is Off, then you must have either 2 or 4 component data. For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first scalar opacity (and gradient opacity) transfer function. Normals will be generated off of the second component. When using gradient based opacity modulation, the gradients are computed off of the second component. For 4 component data, the first three will directly represent RGB (no lookup table). The fourth component will be passed through the first scalar opacity transfer function for opacity and first gradient opacity transfer function for gradient based opacity modulation. Normals will be generated from the fourth component. When using gradient based opacity modulation, the gradients are computed off of the fourth component.
