## Member Function Documentation

const Vector3& Ogre::Ray::getDirection | ( | void |  | ) | const

Gets the direction of the ray.

Definition at line 64 of file OgreRay.h.

const Vector3& Ogre::Ray::getOrigin | ( | void |  | ) | const

Gets the origin of the ray.

Definition at line 59 of file OgreRay.h.

Vector3 Ogre::Ray::getPoint | ( | Real | t | ) | const

Gets the position of a point t units along the ray.

Definition at line 67 of file OgreRay.h.

std::pair<bool, Real> Ogre::Ray::intersects | ( | const Sphere & | s | ) | const

Tests whether this ray intersects the given sphere.

Returns:
  A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint().

Definition at line 102 of file OgreRay.h.

References Ogre::Math::intersects().

std::pair<bool, Real> Ogre::Ray::intersects | ( | const PlaneBoundedVolume & | p | ) | const

Tests whether this ray intersects the given plane bounded volume.

Returns:
  A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint().

std::pair<bool, Real> Ogre::Ray::intersects | ( | const AxisAlignedBox & | box | ) | const

Tests whether this ray intersects the given box.

Returns:
  A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint().

std::pair<bool, Real> Ogre::Ray::intersects | ( | const Plane & | p | ) | const

Tests whether this ray intersects the given plane.

Returns:

Vector3 Ogre::Ray::operator* | ( | Real | t | ) | const

Gets the position of a point t units along the ray.

Definition at line 72 of file OgreRay.h.

void Ogre::Ray::setDirection | ( | const Vector3 & | dir | ) |

Sets the direction of the ray.

Definition at line 62 of file OgreRay.h.

void Ogre::Ray::setOrigin | ( | const Vector3 & | origin | ) |

Sets the origin of the ray.
