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

get()

static const SbViewportRegion & SoViewportRegionElement::get ( SoState *  state )

static

Returns current viewport region from the state.

getClassStackIndex()

static int SoViewportRegionElement::getClassStackIndex ( )

static

Returns the stack id for this element.

getClassTypeId()

static SoType SoViewportRegionElement::getClassTypeId ( )

static

Returns the type identifier for this class.

print()

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

virtual

Prints element (for debugging).

Reimplemented from SoElement.

set()

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.
