DESCRIPTION

33       Represents   an   oriented   plane   in   3D.  This  is  a  lightweight
34       class/datatype that is used for arguments to some Inventor objects.

METHODS

37                         SbPlane()
38                         SbPlane(const SbVec3f &p0, const SbVec3f  &p1,  const
39                              SbVec3f &p2)
40                         SbPlane(const SbVec3f &normal, float distance)
41                         SbPlane(const SbVec3f &normal, const SbVec3f &point)
42          Constructors.  p0,  p1,  and p2 represent three points in the plane.
43          normal is a normal vector, distance is distance from origin to plane
44          along  normal  vector, and point is a point in 3-space for the plane
45          to pass through.
46
47     void                offset(float d)
48          Offset a plane by a given distance.
49
50     SbBool              intersect(const  SbLine  &l,  SbVec3f  &intersection)
51                              const
52          Intersect  line  and  plane, returning TRUE if there is an intersec‐
53          tion, FALSE if line is parallel to plane.
54
55     void                transform(const SbMatrix &matrix)
56          Transforms the plane by the given matrix.
57
58     SbBool              isInHalfSpace(const SbVec3f &point) const
59          Returns TRUE if the given point is within the half-space defined  by
60          the plane.
61
62     const SbVec3f &     getNormal() const
63          Returns normal vector to plane.
64
65     float               getDistanceFromOrigin() const
66          Returns distance from origin to plane.
67
68     int                 operator ==(const SbPlane &p1, const SbPlane &p2)
69     int                 operator !=(const SbPlane &p1, const SbPlane &p2)
70          Equality/inequality comparison operators.
