Detailed Description

The result of a collistion between a Geometry and an euclidian.

A hit is generated when an collision occurs between a Geometry and an euclidian through the Geometry::hits method. The hit class can also be used to describe a "no hit" when no collision occurs by setting the hit date to infinity or simply by using default constructor.

A hit is attached to a surface element, the exact surface location where the hit occurs.

You can also attach a material to the surface element through hit::setMaterial. Typicaly, the material match the surface material, and is set by the Object::hit method.

An order relation is defined for the hits according to there occurrence date. A hit precede an other if its occurence date is prior.

hit()

rt::hit::hit

(

)

This constructor is used to make a "no hit", when no collision occurs.

Member Function Documentation

date()

double rt::hit::date ( ) const

inline

Date of the hit.

May be infinity if no hit occurs.
