Constructor & Destructor Documentation G3D::Plane::Plane (  )  [inline] G3D::Plane::Plane ( const Vector3 &  point0, const Vector3 &  point1, const Vector3 &  point2   ) Constructs a plane from three points. G3D::Plane::Plane ( Vector4  point0, Vector4  point1, Vector4  point2   ) Constructs a plane from three points, where at most two are at infinity (w = 0, not xyz = inf). G3D::Plane::Plane ( const Vector3 &  __normal, const Vector3 &  point   ) The normal will be unitized. G3D::Plane::Plane ( class BinaryInput &  b  )  virtual G3D::Plane::~Plane (  )  [inline, virtual] Member Function Documentation Vector3 G3D::Plane::center (  )  const [inline] Returns normal * distance from origin. Vector3 G3D::Plane::closestPoint ( const Vector3 &  x  )  const [inline] void G3D::Plane::deserialize ( class BinaryInput &  b  )  float G3D::Plane::distance ( const Vector3 &  x  )  const [inline] Returns distance from point to plane. Distance is negative if point is behind (not in plane in direction opposite normal) the plane. void G3D::Plane::flip (  )  Inverts the facing direction of the plane so the new normal is the inverse of the old normal. static Plane G3D::Plane::fromEquation ( float  a, float  b, float  c, float  d   ) [static] bool G3D::Plane::fuzzyContains ( const Vector3 &  point  )  const [inline] Returns true if the point is nearly in the plane. void G3D::Plane::getEquation ( float &  a, float &  b, float &  c, float &  d   ) const void G3D::Plane::getEquation ( double &  a, double &  b, double &  c, double &  d   ) const ax + by + cz + d = 0 void G3D::Plane::getEquation ( Vector3 &  normal, float &  d   ) const void G3D::Plane::getEquation ( Vector3 &  normal, double &  d   ) const Returns the equation in the form:. normal.Dot(Vector3(x, y, z)) + d = 0 bool G3D::Plane::halfSpaceContains ( const Vector4 &  point  )  const [inline] Returns true if point is on the side the normal points to or is in the plane. bool G3D::Plane::halfSpaceContains ( Vector3  point  )  const [inline] Returns true if point is on the side the normal points to or is in the plane. bool G3D::Plane::halfSpaceContainsFinite ( const Vector3 &  point  )  const [inline] Returns true if point is on the side the normal points to or is in the plane. Only call on finite points. Faster than halfSpaceContains. const Vector3& G3D::Plane::normal (  )  const [inline] void G3D::Plane::serialize ( class BinaryOutput &  b  )  const std::string G3D::Plane::toString (  )  const The documentation for this class was generated from the following file: Plane.h Hosted by
