Detailed Description

Bound a ray according to polydata.

Date:

2000/12/10 20:08:48

Revision:

1.14

Thanks:

Thanks to Lisa Sobierajski Avila who developed this class.

The vtkProjectedPolyDataRayBounder can be used to clip viewing rays against the polygons in a vtkPolyData. This is done by projecting the vtkPolyData twice - first capturing a near Z buffer, then capturing a far Z buffer. The values from the Z buffers are decoded according to the current viewing transformation, and the decoded pairs of values (near,far) are returned as distance from the view point for perspective viewing, or distance from the view plane for parallel viewing.

Member Function Documentation

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

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

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

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

void vtkProjectedPolyDataRayBounder::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 vtkObject. Reimplemented in vtkMesaProjectedPolyDataRayBounder, and vtkOpenGLProjectedPolyDataRayBounder.

vtkProjectedPolyDataRayBounder* vtkProjectedPolyDataRayBounder::New (    )  [static]

New method for the class which will return the correct type of ProjectPolyDataRayBounder Reimplemented from vtkObject. Reimplemented in vtkMesaProjectedPolyDataRayBounder, and vtkOpenGLProjectedPolyDataRayBounder.

float* vtkProjectedPolyDataRayBounder::GetRayBounds (  vtkRenderer *    ren )  [virtual]

Get the ray bounds given a renderer. The ray bounds are a two dimensional array of (near,far) values, with the width and height of the array being equal to the width and height of the current viewport in pixel. Reimplemented from vtkRayBounder.

virtual void vtkProjectedPolyDataRayBounder::SetPolyData (  vtkPolyData *    )  [virtual]

Set/Get the PolyData that will be projected for clipping

virtual vtkPolyData* vtkProjectedPolyDataRayBounder::GetPolyData (    )  [virtual]

void vtkProjectedPolyDataRayBounder::SetMatrixSource (  vtkActor *    actor )

Set a matrix source as either an actor or a volume. If a matrix source is set, then the PolyData will first be transformed according to the matrix of the given actor or volume.

void vtkProjectedPolyDataRayBounder::SetMatrixSource (  vtkVolume *    volume )

unsigned long vtkProjectedPolyDataRayBounder::GetMTime (    )  [virtual]

Return the MTime also considering the ivars' MTimes. Reimplemented from vtkObject.

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

Definition at line 105 of file vtkProjectedPolyDataRayBounder.h.

virtual void vtkProjectedPolyDataRayBounder::Build (  vtkPolyData *    pdata )  [protected, virtual]

Create a display list from the poly data. Reimplemented in vtkMesaProjectedPolyDataRayBounder, and vtkOpenGLProjectedPolyDataRayBounder.

virtual float* vtkProjectedPolyDataRayBounder::Draw (  vtkRenderer *    ren, vtkMatrix4x4 *    matrix )  [protected, virtual]

Render the display list and create the near and far buffers Reimplemented in vtkMesaProjectedPolyDataRayBounder, and vtkOpenGLProjectedPolyDataRayBounder.
