Detailed Description

Representation of a ray in space, i.e.

a line with an origin and direction.

Member Function Documentation

getDirection()

const Vector3& ParaEngine::Ray::getDirection ( void  ) const

inline

Gets the direction of the ray.

getOrigin()

const Vector3& ParaEngine::Ray::getOrigin ( void  ) const

inline

Gets the origin of the ray.

getPoint()

Vector3 ParaEngine::Ray::getPoint ( float  t ) const

inline

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

intersects() [1/4]

std::pair<bool, float> ParaEngine::Ray::intersects ( const Plane &  p ) const

inline

Tests whether this ray intersects the given plane.

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().

intersects() [2/4]

std::pair<bool, float> ParaEngine::Ray::intersects ( const PlaneBoundedVolume &  p ) const

inline

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().

intersects() [3/4]

std::pair<bool, float> ParaEngine::Ray::intersects ( const Sphere &  s ) const

inline

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().

intersects() [4/4]

std::pair<bool, float> ParaEngine::Ray::intersects ( const AxisAlignedBox &  box ) const

inline

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().

operator*()

Vector3 ParaEngine::Ray::operator* ( float  t ) const

inline

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

setDirection()

void ParaEngine::Ray::setDirection ( const Vector3 &  dir )

inline

Sets the direction of the ray.

setOrigin()

void ParaEngine::Ray::setOrigin ( const Vector3 &  origin )

inline

Sets the origin of the ray.
