using Ray3D = Ray<ActsScalar, 3>¶
Functions
-
template<typename value_t, size_t DIM>
class Ray - #include <Acts/Utilities/Ray.hpp>
Class which models a ray.
It is defined by a starting point and a direction.
- Template Parameters
value_t – The floating point type to use
DIM – The number of dimensions in which this ray is defined (2 or 3)
Public Types
-
using value_type = value_t
Re expose the value type.
Public Functions
-
Ray(const VertexType &origin, const VertexType &dir)
Constructor from an origin point and a direction.
- Parameters
origin – The origin of the ray
dir – The direction of the ray
-
inline const VertexType &dir() const
Getter for the direction.
- Returns
The direction
-
template<size_t D = DIM, std::enable_if_t<D == 3, int> = 0>
void draw(IVisualization3D &helper, value_type far_distance = 10) const Helper to draw this ray using a given visualization helper.
- Parameters
helper – The visualization helper
far_distance – The “length” of the drawn line representing the ray
-
inline const vertex_array_type &idir() const
Getter for the element wise inverse of the direction.
- Returns
The element wise inverse.
-
inline const VertexType &origin() const
Getter for the origin.
- Returns
The origin
-
std::ostream &toStream(std::ostream &os) const
Write information on this instance to an outstream.
- Parameters
os – The out stream
- Returns
The out stream given as an argument
-
Ray<value_t, DIM> transformed(const transform_type &trf) const
Transforms this ray using a given transform and returns a new instance.
- Parameters
trf – The transform to apply
- Returns
Copy of this ray with the transform applied
