cxResourceVisualization_EXPORT vtkSmartPointer<vtkAppendPolyData> GenerateOverlappingBunchOfSpheres ( int  theta,
int  phi 
)

Generate a bunch of overlapping spheres within one poly data set: one big sphere evenly surrounded by four small spheres that intersect the centered sphere.

Parameters
thetasphere sampling resolution (THETA)
phisphere sampling resolution (PHI)
Returns
the set of spheres within one logical poly data set

cxResourceVisualization_EXPORT bool IsDepthPeelingSupported ( vtkSmartPointer< vtkRenderWindow >  renderWindow,
vtkSmartPointer< vtkRenderer >  renderer,
bool  doItOffScreen 
)

Find out whether this box supports depth peeling. Depth peeling requires a variety of openGL extensions and appropriate drivers.

Parameters
renderWindowa valid openGL-supporting render window
renderera valid renderer instance
doItOffScreendo the test off screen which means that nothing is rendered to screen (this requires the box to support off screen rendering)
Returns
TRUE if depth peeling is supported, FALSE otherwise (which means that another strategy must be used for correct rendering of translucent geometry, e.g. CPU-based depth sorting)

cxResourceVisualization_EXPORT bool SetupEnvironmentForDepthPeeling ( vtkSmartPointer< vtkRenderWindow >  renderWindow,
vtkSmartPointer< vtkRenderer >  renderer,
int  maxNoOfPeels,
double  occlusionRatio 
)

Setup the rendering environment for depth peeling (general depth peeling support is requested).

See also
IsDepthPeelingSupported()
Parameters
renderWindowa valid openGL-supporting render window
renderera valid renderer instance
maxNoOfPeelsmaximum number of depth peels (multi-pass rendering)
occlusionRatiothe occlusion ration (0.0 means a perfect image, >0.0 means a non-perfect image which in general results in faster rendering)
Returns
TRUE if depth peeling could be set up

cxResourceVisualization_EXPORT bool TurnOffDepthPeeling ( vtkSmartPointer< vtkRenderWindow >  renderWindow,
vtkSmartPointer< vtkRenderer >  renderer 
)

Turn off depth peeling.
