Detailed Description

Adaptive volume mapper.

vtkSmartVolumeMapper is a volume mapper that will delegate to a specific volume mapper based on rendering parameters and available hardware. Use the SetRequestedRenderMode() method to control the behavior of the selection. The following options are available:

vtkSmartVolumeMapper::DefaultRenderMode:: Allow the vtkSmartVolumeMapper to select the best mapper based on rendering parameters and hardware support. If GPU ray casting is supported, this mapper will be used for all rendering. If not, then the vtkFixedPointRayCastMapper will be used exclusively. This is the default requested render mode, and is generally the best option. When you use this option, your volume will always be rendered, but the method used to render it may vary based on parameters and platform.

vtkSmartVolumeMapper::RayCastRenderMode:: Use the vtkFixedPointVolumeRayCastMapper for both interactive and still rendering. When you use this option your volume will always be rendered with the vtkFixedPointVolumeRayCastMapper.

vtkSmartVolumeMapper::GPURenderMode:: Use the vtkGPUVolumeRayCastMapper, if supported, for both interactive and still rendering. If the GPU ray caster is not supported (due to hardware limitations or rendering parameters) then no image will be rendered. Use this option only if you have already checked for supported based on the current hardware, number of scalar components, and rendering parameters in the vtkVolumeProperty.

vtkSmartVolumeMapper::GPURenderMode:

You can adjust the contrast and brightness in the rendered image using the FinalColorWindow and FinalColorLevel ivars. By default the FinalColorWindow is set to 1.0, and the FinalColorLevel is set to 0.5, which applies no correction to the computed image. To apply the window / level operation to the computer image color, first a Scale and Bias value are computed:

 scale = 1.0 / this->FinalColorWindow
 bias  = 0.5 - this->FinalColorLevel / this->FinalColorWindow

To compute a new color (R', G', B', A') from an existing color (R,G,B,A) for a pixel, the following equation is used:

 R' = R*scale + bias*A
 G' = G*scale + bias*A
 B' = B*scale + bias*A
 A' = A

Note that bias is multiplied by the alpha component before adding because the red, green, and blue component of the color are already pre-multiplied by alpha. Also note that the window / level operation leaves the alpha component unchanged - it only adjusts the RGB values.

◆ VectorModeType

enum vtkSmartVolumeMapper::VectorModeType

VectorMode is a special rendering mode for 3-component vectors which makes use of GPURayCastMapper's independent-component capabilities.

In this mode, a single component in the vector can be selected for rendering. In addition, the mapper can compute a scalar field representing the magnitude of this vector using a vtkImageMagnitude object (MAGNITUDE mode).

If the InteractiveAdjustSampleDistances flag is enabled, vtkSmartVolumeMapper interactively sets and resets the AutoAdjustSampleDistances flag on the internal volume mapper.

This flag along with InteractiveUpdateRate is useful to adjust volume mapper sample distance based on whether the render is interactive or still. By default, InteractiveAdjustSampleDistances is enabled.

◆ SetAutoAdjustSampleDistances()

virtual void vtkSmartVolumeMapper::SetAutoAdjustSampleDistances ( vtkTypeBool )

virtual

If AutoAdjustSampleDistances is on, the ImageSampleDistance will be varied to achieve the allocated render time of this prop (controlled by the desired update rate and any culling in use).

Note that, this flag is ignored when InteractiveAdjustSampleDistances is enabled. To explicitly set and use this flag, one must disable InteractiveAdjustSampleDistances.

◆ GetAutoAdjustSampleDistances()

virtual vtkTypeBool vtkSmartVolumeMapper::GetAutoAdjustSampleDistances ( )

virtual

If AutoAdjustSampleDistances is on, the ImageSampleDistance will be varied to achieve the allocated render time of this prop (controlled by the desired update rate and any culling in use).

Note that, this flag is ignored when InteractiveAdjustSampleDistances is enabled. To explicitly set and use this flag, one must disable InteractiveAdjustSampleDistances.

◆ AutoAdjustSampleDistancesOn()

virtual void vtkSmartVolumeMapper::AutoAdjustSampleDistancesOn ( )

virtual

If AutoAdjustSampleDistances is on, the ImageSampleDistance will be varied to achieve the allocated render time of this prop (controlled by the desired update rate and any culling in use).

Note that, this flag is ignored when InteractiveAdjustSampleDistances is enabled. To explicitly set and use this flag, one must disable InteractiveAdjustSampleDistances.

◆ AutoAdjustSampleDistancesOff()

virtual void vtkSmartVolumeMapper::AutoAdjustSampleDistancesOff ( )

virtual

If AutoAdjustSampleDistances is on, the ImageSampleDistance will be varied to achieve the allocated render time of this prop (controlled by the desired update rate and any culling in use).

Note that, this flag is ignored when InteractiveAdjustSampleDistances is enabled. To explicitly set and use this flag, one must disable InteractiveAdjustSampleDistances.

◆ SetSampleDistance()

virtual void vtkSmartVolumeMapper::SetSampleDistance ( float )

virtual

Set/Get the distance between samples used for rendering when AutoAdjustSampleDistances is off, or when this mapper has more than 1 second allocated to it for rendering.

If SampleDistance is negative, it will be computed based on the dataset spacing. Initial value is -1.0.
