Detailed Description

OpenGL implementation of volume rendering through ray-casting.

Multiple Inputs

When multiple inputs are rendered simultaneously, it is possible to composite overlapping areas correctly. Inputs are connected directly to the mapper and their parameters (transfer functions, transformations, etc.) are specified through standard vtkVolume instances. These vtkVolume instances are to be registered in a special vtkProp3D, vtkMultiVolume.

Structures related to a particular active input are stored in a helper class (vtkVolumeInputHelper) and helper structures are kept in a port-referenced map (VolumeInputMap). The order of the inputs in the map is important as it defines the order in which parameters are bound to uniform variables (transformation matrices, bias, scale and every other required rendering parameter).

A separate code path is used when rendering multiple-inputs in order to facilitate the co-existance of these two modes (single/multiple), due to current feature incompatibilities with multiple inputs (e.g. texture-streaming, cropping, etc.).

Note: A limited set of the mapper features are currently supported for multiple inputs:

Blending
- Composite (front-to-back)
Transfer functions (defined separately for per input)
- 1D color
- 1D scalar opacity
- 1D gradient magnitude opacity
- 2D scalar-gradient magnitude
Point and cell data
- With the limitation that all of the inputs are assumed to share the same name/id.

◆ IsA()

virtual vtkTypeBool vtkOpenGLGPUVolumeRayCastMapper::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkGPUVolumeRayCastMapper.

◆ PrintSelf()

void vtkOpenGLGPUVolumeRayCastMapper::PrintSelf	(	ostream &	os,

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

◆ GetDepthImage()

void vtkOpenGLGPUVolumeRayCastMapper::GetDepthImage ( vtkImageData * )

overridevirtual

Low level API to export the depth texture as vtkImageData in RenderToImage mode.

Should be implemented by the graphics API specific mapper (GL or other).

Reimplemented from vtkGPUVolumeRayCastMapper.

◆ GetColorImage()

overridevirtual

Low level API to export the color texture as vtkImageData in RenderToImage mode.

Should be implemented by the graphics API specific mapper (GL or other).

◆ SetSharedDepthTexture()

◆ SetPartitions()

void vtkOpenGLGPUVolumeRayCastMapper::SetPartitions	(	unsigned short	x,
		unsigned short	y,
		unsigned short	z
	)

Set a fixed number of partitions in which to split the volume during rendring.

This will force by-block rendering without trying to compute an optimum number of partitions.

◆ PreLoadData()

bool vtkOpenGLGPUVolumeRayCastMapper::PreLoadData	(	vtkRenderer *	ren,
		vtkVolume *	vol
	)

Load the volume texture into GPU memory.

Actual loading occurs in vtkVolumeTexture::LoadVolume. The mapper by default loads data lazily (at render time), so it is most commonly not necessary to call this function. This method is only exposed in order to support on-site loading which is useful in cases where the user needs to know a-priori whether loading will succeed or not.

◆ ReleaseGraphicsResources()

void vtkOpenGLGPUVolumeRayCastMapper::ReleaseGraphicsResources ( vtkWindow * )

overridevirtual

Release any graphics resources that are being consumed by this mapper.

The parameter window could be used to determine which graphic resources to release.
