Intersection() [1/3]

std::pair< Bool_t, TGLLine3 > Intersection	(	const TGLPlane &	p1,
		const TGLPlane &	p2
	)

Find 3D line interestion of this plane with 'other'.

Returns a std::pair

first (Bool_t) second (TGLLine3) kTRUE - planes intersect intersection line between planes kFALSE - no intersect (parallel) undefined

Intersection() [2/3]

std::pair< Bool_t, TGLVertex3 > Intersection	(	const TGLPlane &	p1,

Intersection() [3/3]

std::pair< Bool_t, TGLVertex3 > Intersection	(	const TGLPlane &	plane,
		const TGLLine3 &	line,
		Bool_t	extend
	)

Find intersection of 3D space 'line' with this plane.

If 'extend' is kTRUE then line extents can be extended (infinite length) to find intersection. If 'extend' is kFALSE the fixed extents of line is respected.

The return a std::pair

• first (Bool_t) second (TGLVertex3)
• kTRUE - line/plane intersect intersection vertex on plane
• kFALSE - no line/plane intersect undefined

If intersection is not found (first == kFALSE) & 'extend' was kTRUE (infinite line) this implies line and plane are parallel. If 'extend' was kFALSE, then either line parallel or insufficient length.
