Member Function Documentation

static bool GRE::CLIPPING3D::ClipPoint

(

DPOINT3DH &

point

)

[static]

Clip point.

Returns:

true if point inside unit cube

static bool GRE::CLIPPING3D::ClipPolygon	(	const DOUBLE_ARRAY< DPOINT3DH > &	input,
		DOUBLE_ARRAY< DPOINT3DH > &	output
	)			[static]

Clip plane polygon input.

If polygon intersects unit cube than output contains polygon of intersection in return.

Returns:

true if polygon intersects unit cube

static bool GRE::CLIPPING3D::ClipSegment	(	DPOINT3DH &	point1,
		DPOINT3DH &	point2
	)			[static]

Clip segment with endpoints point1 and point2.

If segment intersects unit cube than point1 and point2 contains endpoints of intersection in return.

Returns:

true if segment intersects unit cube
