Member Function Documentation

void ActiveCoordinateFrame::AlignWith	(	const Point3f	primary,
		const Point3f	secondary,
		const char	axis_1,
		const char	axis_2
	)			`[virtual]`

Align the coordinate frame to one or two directions.

If the primary direction of alignment is null this function does nothing, otherwise two rotations are performed: the first rotation aligns the axis named axis_1 to the primary direction of alignment, the second rotation never moves axis_1 away from the primary direction.

If the secondary direction of alignment is not null and is not parallel to the primary direction the axis named axis_2 is rotated as much as possible to be aligned to secondary direction.

If the secondary direction of alignment is null the axis named axis_2 is rotated as much as possible to be realigned to its old direction, if this is impossible the remaining axis is used.

Parameters:

	primary	the primary direction of alignment.
	secondary	the secondary direction of alignment.
	axis_1	the name of the axis to align to the primary direction, must be a char choosen from 'X', 'Y' and 'Z'
	axis_2	the name of the axis to align to the secondary direction, must be different from axis_1 and must be a char choosen from 'X', 'Y', 'Z' and ' '; if the char is ' ' the axis is choosen automatically.
