Public Methods

static bool	Plane ( const csVector3& u, const csVector3& v, const csPlane& p, csVector3& isect, float& dist) Intersect a 3D segment with a plane
static void	Plane ( const csVector3& u, const csVector3& v, const csVector3& normal, const csVector3& a, csVector3& isect) Intersect a 3D segment with a plane
static bool	Plane ( const csVector3& u, const csVector3& v, float A, float B, float C, float D, csVector3& isect, float& dist) Intersect a 3D segment with a plane
static float	XFrustrum ( float A, const csVector3& u, const csVector3& v, csVector3& isect) Intersect a 3D segment with the frustrum plane Ax + z = 0
static float	YFrustrum ( float B, const csVector3& u, const csVector3& v, csVector3& isect) Intersect a 3D segment with the frustrum plane By + z = 0
static float	Z0Plane ( const csVector3& u, const csVector3& v, csVector3& isect) Intersect a 3D segment with the z = 0 plane
static float	ZPlane (float zval, const csVector3& u, const csVector3& v, csVector3& isect) Intersect a 3D segment with the plane z = zval

static void Plane( const csVector3& u, const csVector3& v, const csVector3& normal, const csVector3& a, csVector3& isect)

Intersect a 3D segment with a plane. Returns true if there is an intersection, with the intersection point returned in isect.

static bool Plane( const csVector3& u, const csVector3& v, float A, float B, float C, float D, csVector3& isect, float& dist)

Intersect a 3D segment with a plane. Returns true if there is an intersection, with the intersection point returned in isect. The distance from u to the intersection point is returned in dist. The distance that is returned is a normalized distance with respect to the given input vector. i.e. a distance of 0.5 means that the intersection point is halfway u and v.

static bool Plane( const csVector3& u, const csVector3& v, const csPlane& p, csVector3& isect, float& dist)

Intersect a 3D segment with a plane. Returns true if there is an intersection, with the intersection point returned in isect. The distance from u to the intersection point is returned in dist. The distance that is returned is a normalized distance with respect to the given input vector. i.e. a distance of 0.5 means that the intersection point is halfway u and v.

static float Z0Plane( const csVector3& u, const csVector3& v, csVector3& isect)

Intersect a 3D segment with the z = 0 plane. Assumes that there is an intersection (fails if the segment is parallel to the plane), and returns the distance from u to the intersection point. The intersection point is returned in isect.

static float ZPlane(float zval, const csVector3& u, const csVector3& v, csVector3& isect)

Intersect a 3D segment with the plane z = zval. Assumes that there is an intersection (fails if the segment is parallel to the plane), and returns the distance from u to the intersection point. The intersection point is returned in isect.

static float XFrustrum( float A, const csVector3& u, const csVector3& v, csVector3& isect)

Intersect a 3D segment with the frustrum plane Ax + z = 0. Assumes an intersection, and returns the intersection point in isect.

static float YFrustrum( float B, const csVector3& u, const csVector3& v, csVector3& isect)

Intersect a 3D segment with the frustrum plane By + z = 0. Assumes an intersection, and returns the intersection point in isect.
