Member Function Documentation

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

Find the intersection of two planes. which in the general case is a line. The line is provided as a ray (origin and direction).

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

Compute Ray-Plane intersection.

Origin,DirectionThe position and direction that define the ray.
fDistanceThe distance along the ray to the intersection point.
IntersectionThe intersection point.
fEpsilonSmall value to test for numeric equivalenccy.
The intersection result (PARALLEL, FACING_AWAY, or INTERSECTING)
