Member Function Documentation

void GRE::SCREENPLANE::Clear

(

)

[inline]

Clear plane parameters.

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

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

Set plane by three points in homogenius coordinates.
