SoGLUpdateAreaElement::~SoGLUpdateAreaElement | ( | ) | [protected, virtual] |
The destructor.
SoType SoGLUpdateAreaElement::getClassTypeId | ( | void | ) | [static] |
This static method returns the class type.
Reimplemented from SoElement.
int SoGLUpdateAreaElement::getClassStackIndex | ( | void | ) | [static] |
This static method returns the state stack index for the class.
Reimplemented from SoElement.
void * SoGLUpdateAreaElement::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.
void SoGLUpdateAreaElement::initClass | ( | void | ) | [static] |
This static method initializes static data for the SoGLUpdateAreaElement class.
Reimplemented from SoElement.
SoElement * SoGLUpdateAreaElement::copyMatchInfo | ( | void | ) | const [virtual] |
This function creates a copy of the element that contains enough information to enable the matches() function to work.
Used to help with scenegraph traversal caching operations.
Implements SoElement.
void SoGLUpdateAreaElement::set | ( | SoState *const | state, | |
const SbVec2f & | origin, | |||
const SbVec2f & | size | |||
) | [static] |
Sets the update area. This can, for instance, be used when rendering in the front buffer, to only render parts of the scene during a window expose event. origin and size is in normalized window coordinates.
SbVec2f SoGLUpdateAreaElement::getDefaultOrigin | ( | void | ) | [static] |
Returns the default update area origin, (0,0).
SbVec2f SoGLUpdateAreaElement::getDefaultSize | ( | void | ) | [static] |
Returns the default update area size, (1,1).
