Detailed Description

Stores the current projection matrix.

This element stores the current projection matrix - the projective part of the matrix set up by the camera. Because most operations on this matrix are atomic, it is considered a non-accumulating element.

Member Function Documentation

static const SbMatrix& SoProjectionMatrixElement::get ( SoState state  )  [static]

Returns current matrix from the state.

static int SoProjectionMatrixElement::getClassStackIndex (  )  [static]

Returns the stack id for this element.

Reimplemented from SoReplacedElement.

Reimplemented in SoGLProjectionMatrixElement.

static SoType SoProjectionMatrixElement::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoReplacedElement.

Reimplemented in SoGLProjectionMatrixElement.

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

Prints element (for debugging).

Reimplemented from SoReplacedElement.

static void SoProjectionMatrixElement::set ( SoState state,
SoNode node,
const SbMatrix matrix,
SbBool  sendToGL = TRUE 
) [static]

Sets the projection matrix to the given matrix.

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