Detailed Description

An isosurface ray caster for volumes.

Date:

2000/12/10 20:08:59

Revision:

1.18

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)

Member Function Documentation

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkVolumeRayCastFunction.

int vtkVolumeRayCastIsosurfaceFunction::IsTypeOf (  const char *    type )  [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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkVolumeRayCastFunction.

virtual int vtkVolumeRayCastIsosurfaceFunction::IsA (  const char *    type )  [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 vtkVolumeRayCastFunction.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkVolumeRayCastFunction.

void vtkVolumeRayCastIsosurfaceFunction::PrintSelf (  ostream &    os, vtkIndent    index )  [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 vtkObject.

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 Reimplemented from vtkVolumeRayCastFunction.

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

Set/Get the value of IsoValue.

virtual float vtkVolumeRayCastIsosurfaceFunction::GetIsoValue (    )  [virtual]

void vtkVolumeRayCastIsosurfaceFunction::CastRay (  VTKRayCastRayInfo *    rayInfo, VTKRayCastVolumeInfo *    volumeInfo )  [virtual]

Reimplemented from vtkVolumeRayCastFunction.

void vtkVolumeRayCastIsosurfaceFunction::operator= (  const vtkVolumeRayCastIsosurfaceFunction &    )  [inline, protected]

Definition at line 99 of file vtkVolumeRayCastIsosurfaceFunction.h.

void vtkVolumeRayCastIsosurfaceFunction::SpecificFunctionInitialize (  vtkRenderer *    ren, vtkVolume *    vol, VTKRayCastVolumeInfo *    volumeInfo, vtkVolumeRayCastMapper *    mapper )  [protected, virtual]

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