Detailed Description

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

Simple n-dimensional ray segment data structure.

Along with the ray origin and direction, this data structure additionally stores a ray segment mint, maxt, as well as the componentwise reciprocals of the ray direction. That is just done for convenience, as these values are frequently required.

Remarks

Important: be careful when changing the ray direction. You must call update() to compute the componentwise reciprocals as well, or Nori's ray-triangle intersection code will go haywire.
