Member Function Documentation

void GRE::SCREENPLANE::Clear (   )  [inline]

Clear plane parameters. Definition at line 219 of file 3dutils.h.

bool GRE::SCREENPLANE::GetCellExtents (  const INT32  line, const INT32  column, DPOINT3DH  hpoints[4] )

Get extents on screen plane that projected to screen at screen pixel with coordinates (column, line). Returns: true if extents exist

bool GRE::SCREENPLANE::GetPoint (  const INT32  line, const INT32  column, DPOINT3DH &  point )

Get point on screen plane that projected to screen at center of screen pixel with coordinates (column, line). Returns: true if point exists

bool GRE::SCREENPLANE::IsSet (   )  const [inline]

Is plane set. Returns: true if plane is set Definition at line 225 of file 3dutils.h.

void GRE::SCREENPLANE::Set (  const DPOINT3DH &  pt1, const DPOINT3DH &  pt2, const DPOINT3DH &  pt3 )

Set plane by three points in homogenius coordinates. Parameters: pt1  Constructor Destructor
