This element stores a logical viewport region subset.
Returns the current portion from the state.
static int SoModifyLogicalViewportElement::getClassStackIndex | ( | ) | [static] |
Returns the stack id for this element.
Reimplemented from SoElement.
static SoType SoModifyLogicalViewportElement::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoElement.
static SbVec4f SoModifyLogicalViewportElement::getDefault | ( | ) | [inline, static] |
Returns the default viewport region.
static SoModifyLogicalViewportElement* SoModifyLogicalViewportElement::getInstance | ( | const SoState * | state, | |
SbBool & | elemIsSet | |||
) | [static] |
Returns the top (current) instance of the element in the state.
Note it does NOT cause cache dependency! It also casts away the const.
virtual void SoModifyLogicalViewportElement::print | ( | FILE * | fp | ) | const [virtual] |
Prints element (for debugging).
Reimplemented from SoElement.
static void SoModifyLogicalViewportElement::set | ( | SoState * | state, | |
const SbVec4f & | portion | |||
) | [static] |
Sets the portion of the viewport.
