Detailed Description

The SoClipPlaneElement class is used to manage the clip plane stack.

Constructor & Destructor Documentation

SoClipPlaneElement::~SoClipPlaneElement () [protected, virtual]The destructor.

Member Function Documentation

void SoClipPlaneElement::initClass (void) [static]Initialize relevant common data for all instances, like the type system.

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLClipPlaneElement.

void SoClipPlaneElement::add (SoState *const state, SoNode *const node, const SbPlane & plane) [static]Adds plane as an active plane. Calls addToElt() to do the job.

const SoClipPlaneElement * SoClipPlaneElement::getInstance (SoState *const state) [static]Returns the current (top-of-stack) element.

int SoClipPlaneElement::getNum (void) constReturns the current number of active clipping planes.

const SbPlane & SoClipPlaneElement::get (const int index, const SbBool inworldspace = 1) constReturns the 'th plane.

void SoClipPlaneElement::addToElt (const SbPlane & plane, const SbMatrix & modelMatrix) [protected, virtual]This method adds the clipping plane, plane, to an instance. modelmatrix is the current model matrix.

Reimplemented in SoGLClipPlaneElement.

Member Data Documentation

SoClipPlaneElement::planes [protected]List of currently active planes.

SoClipPlaneElement::startIndex [protected]Index of first clip plane in this element. Used to disable clip planes in SoGLClipPlaneElement::pop().
