SPAbase Global Function coordinate_transf

SPAtransf coordinate_transf(	SPAposition const&	`new_origin`,
	SPAunit_vector const&	`new_x_axis`,
	SPAunit_vector const&	`new_y_axis`)

Constructs a coordinate transformation.

Role: Creates a transformation that carries the origin to the given position, and the x-axis and y-axis to the given unit vectors. If the second unit vector is not orthogonal to the first, this method uses an orthogonal unit vector in the plane of the two given vectors to direct the y-axis.

Effect: System routine

Parameters:

new_origin: position to which the origin is to be translated.
new_x_axis: vector with which the x-axis is to be aligned.
new_y_axis: vector with which the y-axis is to be aligned.
