The SoClipPlaneElement class is used to manage the clip plane stack.
SoClipPlaneElement::~SoClipPlaneElement | ( | ) | [protected, virtual] |
The destructor.
SoType SoClipPlaneElement::getClassTypeId | ( | void | ) | [static] |
This static method returns the class type.
Reimplemented from SoAccumulatedElement.
Reimplemented in SoGLClipPlaneElement.
int SoClipPlaneElement::getClassStackIndex | ( | void | ) | [static] |
This static method returns the state stack index for the class.
Reimplemented from SoAccumulatedElement.
Reimplemented in SoGLClipPlaneElement.
void * SoClipPlaneElement::createInstance | ( | void | ) | [static] |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Reimplemented in SoGLClipPlaneElement.
void SoClipPlaneElement::initClass | ( | void | ) | [static] |
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoAccumulatedElement.
Reimplemented in SoGLClipPlaneElement.
void SoClipPlaneElement::init | ( | SoState * | state | ) | [virtual] |
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.
Reimplemented from SoAccumulatedElement.
Reimplemented in SoGLClipPlaneElement.
void SoClipPlaneElement::push | ( | SoState * | state | ) | [virtual] |
This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.
Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().
Reimplemented from SoAccumulatedElement.
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 | ) | const |
Returns the current number of active clipping planes.
const SbPlane & SoClipPlaneElement::get | ( | const int | index, |
const SbBool | inworldspace = TRUE |
||
) | const |
Returns 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.
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().
