Detailed Description

template<class T>
struct EBGeometry::RayT< T >

A ray: the points origin + t * direction.

The queries take the direction to be of unit length, so that t is a distance along the ray. This is checked only with assertions on (EBGEOMETRY_EXPECT): with another length, a marched query steps the wrong distance and can step over the surface.

Template Parameters

T	Floating-point precision.

The point at a distance along the ray.

Parameters

[in]

a_t

Distance along the ray.

Returns

origin + a_t * direction.
