DESCRIPTION
Represents an oriented plane in 3D. This is a lightweight class/datatype
that is used for arguments to some Inventor objects. Note that there are
no Create or Delete functions available for this class. SbPlane's should
be declared and/or malloc'd as standard C structs:
/* This is defined in Inventor_c/SbLinear.h: */
struct SbPlane {
struct SbVec3f normalVec;
float distance;
};
typedef SbPlane SbPln;
/* This is what your code should look like: */
SbPlane p;
SbV3fSetX_Y_Z( p.normalVec, 1.0, 0.0, 0.0 );
p.distance = 3.0;
FUNCTIONS
void SbPlnOffset(SbPln *this, float d)
Offset a plane by a given distance.

SbBool SbPlnIntersect(const SbPln *this, const SbLine *l,
SbVec3f *intersection)
Intersect line and plane, returning TRUE if there is an
intersection, FALSE if line is parallel to plane.
void SbPlnTransform(SbPln *this, const SbMatrix *matrix)
Transforms the plane by the given matrix.
SbBool SbPlnIsInHalfSpace(const SbPln *this, const SbVec3f
*point)
Returns TRUE if the given point is within the half-space defined by
the plane.
int SbPlnIsEq(SbPln *this, const SbPlane *p1, const
SbPlane *p2)
int SbPlnIsNEq(SbPln *this, const SbPlane *p1, const
SbPlane *p2)
Equality/inequality comparison operators.
