Detailed Description

An isosurface ray caster for volumes.

vtkVolumeRayCastIsosurfaceFunction is a volume ray cast function that intersects a ray with an analytic isosurface in a scalar field. The color and shading parameters are defined in the vtkVolumeProperty of the vtkVolume, as well as the interpolation type to use when locating the surface (either a nearest neighbor approach or a tri-linear interpolation approach)

virtual const char* vtkVolumeRayCastIsosurfaceFunction::GetClassName (  )  [virtual]

Reimplemented from vtkVolumeRayCastFunction.

static int vtkVolumeRayCastIsosurfaceFunction::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkVolumeRayCastFunction.

virtual int vtkVolumeRayCastIsosurfaceFunction::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkVolumeRayCastFunction.

static vtkVolumeRayCastIsosurfaceFunction* vtkVolumeRayCastIsosurfaceFunction::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkVolumeRayCastFunction.

void vtkVolumeRayCastIsosurfaceFunction::PrintSelf ( ostream &  os,
vtkIndent  indent 
) [virtual]

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.

Reimplemented from vtkVolumeRayCastFunction.

static vtkVolumeRayCastIsosurfaceFunction* vtkVolumeRayCastIsosurfaceFunction::New (  )  [static]

Construct a new vtkVolumeRayCastIsosurfaceFunction

Reimplemented from vtkObject.

float vtkVolumeRayCastIsosurfaceFunction::GetZeroOpacityThreshold ( vtkVolume vol  )  [virtual]

Get the scalar value below which all scalar values have 0 opacity

Implements vtkVolumeRayCastFunction.

virtual void vtkVolumeRayCastIsosurfaceFunction::SetIsoValue ( double   )  [virtual]

Set/Get the value of IsoValue.

virtual double vtkVolumeRayCastIsosurfaceFunction::GetIsoValue (  )  [virtual]

Set/Get the value of IsoValue.

void vtkVolumeRayCastIsosurfaceFunction::CastRay ( vtkVolumeRayCastDynamicInfo dynamicInfo,
vtkVolumeRayCastStaticInfo staticInfo 
) [virtual]

void vtkVolumeRayCastIsosurfaceFunction::SpecificFunctionInitialize ( vtkRenderer ren,
vtkVolume vol,
vtkVolumeRayCastStaticInfo staticInfo,
vtkVolumeRayCastMapper mapper 
) [protected, virtual]

This method gives the subclass a chance to do any special initialization that it may need to do BTX

Implements vtkVolumeRayCastFunction.
