Detailed Description

An abstract class for bounding rays.

Date:

2000/12/10 20:08:49

Revision:

1.13

vtkRayBounder is an abstract class for bounding view rays during ray casting. Each concrete subclass must have a GetRayBounds method which, given a renderer, produces a floating point array that is w*h*2 (w = width of viewport, h = height of viewport). For each pixel, this array contains the near and far clipping values for the corresponding ray. A value of -1 means no clipping should be performed on that ray.

Member Function Documentation

virtual const char* vtkRayBounder::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 vtkObject. Reimplemented in vtkMesaProjectedPolyDataRayBounder, vtkOpenGLProjectedPolyDataRayBounder, and vtkProjectedPolyDataRayBounder.

int vtkRayBounder::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 vtkObject. Reimplemented in vtkMesaProjectedPolyDataRayBounder, vtkOpenGLProjectedPolyDataRayBounder, and vtkProjectedPolyDataRayBounder.

virtual int vtkRayBounder::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 vtkObject. Reimplemented in vtkMesaProjectedPolyDataRayBounder, vtkOpenGLProjectedPolyDataRayBounder, and vtkProjectedPolyDataRayBounder.

vtkRayBounder* vtkRayBounder::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 vtkObject. Reimplemented in vtkMesaProjectedPolyDataRayBounder, vtkOpenGLProjectedPolyDataRayBounder, and vtkProjectedPolyDataRayBounder.

virtual float* vtkRayBounder::GetRayBounds (  vtkRenderer *    ren )  [pure virtual]

Get the ray bounds - a floating point array with two values for every pixel in the viewport. These values indicate near and far clipping distances, or -1 for no clipping. Reimplemented in vtkProjectedPolyDataRayBounder.

virtual void vtkRayBounder::ReleaseGraphicsResources (  vtkWindow *    )  [inline, virtual]

Release any graphics resources that are being consumed by this ray bounder. The parameter window could be used to determine which graphic resources to release. Reimplemented in vtkMesaProjectedPolyDataRayBounder, and vtkOpenGLProjectedPolyDataRayBounder. Definition at line 79 of file vtkRayBounder.h.

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

Definition at line 86 of file vtkRayBounder.h.
