Detailed Description

template<typename DT_>
struct FEAT::Geometry::IntersectionData< DT_ >

Contains information about a ray-primitive intersection.

Template Parameters

DT_

Data type

Contains the distance along the ray of the point(s) where a ray enters and exists some primitive shape.

Entry and exit points can differ. For example in case of a coplanar ray-triagle pair. In that case the part of the ray that overlaps the triangle is counted as an intersection and t_entry gives the first point of overlap and t_exit gives the last point of overlap.

In case of a clean intersection, for example between a ray and a non coplanar triangle, t_entry and t_exit will be identical.

The exit point t_exit is guaranteed to be identical to t_entry or further along the ray.
