Constructor & Destructor Documentation G3D::Ray::Ray (  )  [inline] G3D::Ray::Ray ( class BinaryInput &  b  )  Member Function Documentation Vector3 G3D::Ray::closestPoint ( const Vector3 &  point  )  const [inline] Returns the closest point on the Ray to point. void G3D::Ray::deserialize ( class BinaryInput &  b  )  float G3D::Ray::distance ( const Vector3 &  point  )  const [inline] Returns the closest distance between point and the Ray. static Ray G3D::Ray::fromOriginAndDirection ( const Vector3 &  point, const Vector3 &  direction   ) [inline, static] Creates a Ray from a origin and a (nonzero) direction. Vector3 G3D::Ray::intersection ( const class Plane &  plane  )  const Returns the point where the Ray and plane intersect. If there is no intersection, returns a point at infinity. Planes are considered one-sided, so the ray will not intersect a plane where the normal faces in the traveling direction. float G3D::Ray::intersectionTime ( const Triangle &  triangle, double &  w0, double &  w1, double &  w2   ) const [inline] float G3D::Ray::intersectionTime ( const Triangle &  triangle  )  const [inline] float G3D::Ray::intersectionTime ( const Vector3 &  vert0, const Vector3 &  vert1, const Vector3 &  vert2, double &  w0, double &  w1, double &  w2   ) const [inline] float G3D::Ray::intersectionTime ( const Vector3 &  vert0, const Vector3 &  vert1, const Vector3 &  vert2   ) const [inline] float G3D::Ray::intersectionTime ( const Vector3 &  vert0, const Vector3 &  vert1, const Vector3 &  vert2, const Vector3 &  edge01, const Vector3 &  edge02   ) const [inline] Ray-triangle intersection for a 1-sided triangle.

Referenced Code: http://www.acm.org/jgt/papers/MollerTrumbore97/ http://www.graphics.cornell.edu/pubs/1997/MT97.html float G3D::Ray::intersectionTime ( const Vector3 &  v0, const Vector3 &  v1, const Vector3 &  v2, const Vector3 &  edge01, const Vector3 &  edge02, double &  w0, double &  w1, double &  w2   ) const [inline] The three extra arguments are the weights of vertices 0, 1, and 2 at the intersection point; they are useful for texture mapping and interpolated normals. float G3D::Ray::intersectionTime ( const class AABox &  box  )  const float G3D::Ray::intersectionTime ( const class Box &  box  )  const float G3D::Ray::intersectionTime ( const class Plane &  plane  )  const float G3D::Ray::intersectionTime ( const class Sphere &  sphere  )  const Returns the distance until intersection with the (solid) sphere. Will be 0 if inside the sphere, inf if there is no intersection. The ray direction is not normalized. If the ray direction has unit length, the distance from the origin to intersection is equal to the time. If the direction does not have unit length, the distance = time * direction.length(). See also the G3D::CollisionDetection "movingPoint" methods, which give more information about the intersection. Ray G3D::Ray::reflect ( const Vector3 &  newOrigin, const Vector3 &  normal   ) const Reflects about the normal using G3D::Vector3::reflectionDirection and bumps the ray slightly from the newOrigin. Ray G3D::Ray::refract ( const Vector3 &  newOrigin, const Vector3 &  normal, float  iInside, float  iOutside   ) const Refracts about the normal using G3D::Vector3::refractionDirection and bumps the ray slightly from the newOrigin. void G3D::Ray::serialize ( class BinaryOutput &  b  )  const Ray G3D::Ray::unit (  )  const [inline] Member Data Documentation Vector3 G3D::Ray::direction Not unit length.
