Detailed Description A plane in 3d space. (C) 2004 RadonLabs GmbH Definition at line 16 of file plane.h. Public Member Functions   plane ()   default constructor   plane (float A, float B, float C, float D)   constructor 1   plane (const plane &p)   constructor 2   plane (const vector3 &v0, const vector3 &v1, const vector3 &v2)   constructor 3 void  set (float A, float B, float C, float D)   set contents void  set (const vector3 &v0, const vector3 &v1, const vector3 &v2)   construct plane from 3 vectors float  distance (const vector3 &v) const   compute distance of point to plane vector3  normal () const   get plane normal bool  intersect (const line3 &l, float &t) const   get intersecting t of line with one sided plane bool  intersect (const plane &p, line3 &l) const   get plane/plane intersection Public Attributes float  a float  b float  c float  d Constructor & Destructor Documentation plane::plane (   )  [inline]   default constructor Definition at line 47 of file plane.h. plane::plane (  float  A, float  B, float  C, float  D )  [inline]   constructor 1 Definition at line 60 of file plane.h. plane::plane (  const plane &  p  )  [inline]   constructor 2 Definition at line 73 of file plane.h. plane::plane (  const vector3 &  v0, const vector3 &  v1, const vector3 &  v2 )  [inline]   constructor 3 Definition at line 115 of file plane.h.

Definition at line 101 of file plane.h. float plane::distance (  const vector3 &  v  )  const [inline]   compute distance of point to plane Computes the distance of a point to the plane. Return 0.0 if the point is on the plane. Definition at line 127 of file plane.h. vector3 plane::normal (   )  const [inline]   get plane normal Returns the plane normal. Definition at line 138 of file plane.h. bool plane::intersect (  const line3 &  l, float &  t )  const [inline]   get intersecting t of line with one sided plane Get intersecting t of line with one-sided plane. Returns false if the line is parallel to the plane. If the given line intersects with the plane, plugging the value t into the line equation produces the point of intersection. The following code snippet shows the way to get the intersection point between a line and a plane: if (p.intersect(l, t)) { vector3 intersection = l.b + t*l.m; } Definition at line 162 of file plane.h. bool plane::intersect (  const plane &  p, line3 &  l )  const [inline]   get plane/plane intersection Get plane/plane intersection. Return false if planes are parallel. Definition at line 183 of file plane.h.
