Detailed Description

template<typename _PointType, typename _VectorType>
struct mitsuba::TRay< _PointType, _VectorType >

Simple n-dimensional ray data structure with minimum / maximum extent information.

The somewhat peculiar ordering of the attributes is due to alignment purposes and should not be changed.

Constructor & Destructor Documentation

template<typename _PointType , typename _VectorType >

mitsuba::TRay< _PointType, _VectorType >::TRay ( )

inline

Construct a new ray.

template<typename _PointType , typename _VectorType >

mitsuba::TRay< _PointType, _VectorType >::TRay ( const TRay< _PointType, _VectorType > &  ray )

inline

Copy constructor (1)

template<typename _PointType , typename _VectorType >

mitsuba::TRay< _PointType, _VectorType >::TRay ( const TRay< _PointType, _VectorType > &  ray, Scalar  mint, Scalar  maxt  )

inline

Copy constructor (2)

template<typename _PointType , typename _VectorType >

mitsuba::TRay< _PointType, _VectorType >::TRay ( const PointType &  o, Scalar  time  )

inline

Construct a new ray, while not specifying a direction yet.

template<typename _PointType , typename _VectorType >

mitsuba::TRay< _PointType, _VectorType >::TRay ( const PointType &  o, const VectorType &  d, Scalar  time  )

inline

Construct a new ray.

template<typename _PointType , typename _VectorType >

mitsuba::TRay< _PointType, _VectorType >::TRay ( const PointType &  o, const VectorType &  d, Scalar  mint, Scalar  maxt, Scalar  time  )

inline

Construct a new ray.

Member Function Documentation

template<typename _PointType , typename _VectorType >

PointType mitsuba::TRay< _PointType, _VectorType >::operator() ( Scalar  t ) const

inline

Return the position of a point along the ray.

Remarks

In the Python bindings, this operator is exposed as a function named eval – i.e. position lookups should be written as ray.eval(t)

template<typename _PointType , typename _VectorType >

void mitsuba::TRay< _PointType, _VectorType >::setDirection ( const VectorType &  dir )

inline

Set the direction and update the reciprocal.

template<typename _PointType , typename _VectorType >

void mitsuba::TRay< _PointType, _VectorType >::setOrigin ( const PointType &  pos )

inline

Set the origin.

template<typename _PointType , typename _VectorType >

void mitsuba::TRay< _PointType, _VectorType >::setTime ( Scalar  tval )

inline

Set the time.

template<typename _PointType , typename _VectorType >

std::string mitsuba::TRay< _PointType, _VectorType >::toString ( ) const

inline

Return a string representation of this ray.

Member Data Documentation

template<typename _PointType , typename _VectorType >

VectorType mitsuba::TRay< _PointType, _VectorType >::d

Ray direction.

template<typename _PointType , typename _VectorType >

VectorType mitsuba::TRay< _PointType, _VectorType >::dRcp

template<typename _PointType , typename _VectorType >

Scalar mitsuba::TRay< _PointType, _VectorType >::maxt

Maximum range for intersection tests.

template<typename _PointType , typename _VectorType >

Scalar mitsuba::TRay< _PointType, _VectorType >::mint

Minimum range for intersection tests.

template<typename _PointType , typename _VectorType >

PointType mitsuba::TRay< _PointType, _VectorType >::o

Ray origin.

template<typename _PointType , typename _VectorType >

Float mitsuba::TRay< _PointType, _VectorType >::time

Time value associated with this ray.
