Detailed Description

represents a frame transformation in 3D space (rotation + translation)

if V2 = Frame*V1 (V2 expressed in frame A, V1 expressed in frame B) then V2 = Frame.M*V1+Frame.p

Frame.M contains columns that represent the axes of frame B wrt frame A Frame.p contains the origin of frame B expressed in frame A.

bool Equal	(	const Frame &	a,
		const Frame &	b,
		double	eps = `epsilon`
	)			`[friend]`

do not use operator == because the definition of Equal(.,.) is slightly different. It compares whether the 2 arguments are equal in an eps-interval

bool operator!=	(	const Frame &	a,
		const Frame &	b
	)			`[friend]`

The literal inequality operator!=().
