ParametricPlane

public ParametricPlane(Point p,
                       Vector normal)

Construct a parametric plane with the specified point and normal. It is not specified how the orthogonal basis is constructed except that the third basis-vector will be the normal vector.

Method Detail

projectPoint

public double[] projectPoint(Point v)

Projects the point v onto this plane and returns the parameters of the projected point (scaling of v1, of v2 and finally the distance or scaling along n). 9HOps

intersectionParameter

public double intersectionParameter(Line l)

Returns a parameter setting for the line describing the intersection with this plane. Assumes there's a point intersection.
