Detailed Description

Stores the current viewport region.

This element stores the current viewport region, which indicates which part of the window is being rendered into. This information is also needed during picking and bounding box computation to determine sizes/locations of screen-space objects.

Member Function Documentation

static const SbViewportRegion& SoViewportRegionElement::get ( SoState state  )  [static]

Returns current viewport region from the state.

static int SoViewportRegionElement::getClassStackIndex (  )  [static]

Returns the stack id for this element.

Reimplemented from SoElement.

static SoType SoViewportRegionElement::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoElement.

virtual void SoViewportRegionElement::print ( FILE *  fp  )  const [virtual]

Prints element (for debugging).

Reimplemented from SoElement.

static void SoViewportRegionElement::set ( SoState state,
const SbViewportRegion vpReg,
SbBool  sendToGL = TRUE 
) [static]

Sets the viewport region.

This method will (indirectly) call glViewport with the new values unless the 'sendToGL' parameter is explicitly FALSE.
