Member Function Documentation

const FPlane::IntersectionType FPlane::Intersection (  const FPlane &  Plane, FPoint3 &  Origin, FPoint3 &  Direction, float  fEpsilon = 0.0 )  const

Intersection of two planes. Find the intersection of two planes. which in the general case is a line. The line is provided as a ray (origin and direction). Returns: status, which is either INTERSECTING, COPLANAR, or PARALLEL. In the case of INTERSECTING, then the Origin and Direction parameters describe the line of intersection.

const FPlane::IntersectionType FPlane::RayIntersection (  const FPoint3 &  Origin, const FPoint3 &  Direction, float &  fDistance, FPoint3 &  Intersection, float  fEpsilon = 0.0 )  const

Intersection of ray with plane. Compute Ray-Plane intersection. Parameters: Origin,Direction  The position and direction that define the ray. fDistance  The distance along the ray to the intersection point. Intersection  The intersection point. fEpsilon  Small value to test for numeric equivalenccy. Returns: The intersection result (PARALLEL, FACING_AWAY, or INTERSECTING)
