DESCRIPTION

64       This node creates texture coordinates for points on an object's surface
65       by projecting them onto a plane. The directionS and  directionT  fields
66       define the plane. The S coordinate is computed as the distance from the
67       object-space origin along the vector specified in the directionS field.
68       The T coordinate is computed similarly, using the directionT field.
69
70       The  length  of  the  direction  vector is also taken into account. For
71       example, assume directionS is (0.5, 0, 0) and directionT is (0, 1,  0).
72       The square defined by the (x, y, z) vertices:
73
74          (-1, -1, 0) (1, -1, 0) (1, 1, 0) (-1, 1, 0)
75
76     will be assigned the (s, t) texture coordinates:
77
78          (-2, -1) (2, -1) (2, 1) (-2, 1)
