Ray2D Struct Reference

Represents a 2D ray defined by an origin point and a translation vector. More...

#include <PhysicsWorld2D.h>

Public Member Functions
Vec2	endPoint () const
	Returns the end point of the ray.

Static Public Member Functions
static Ray2D	fromPoints (const Vec2 &start, const Vec2 &end)
	Construct a ray from two points.

Public Attributes
Vec2	origin
	The starting point of the ray.
Vec2	translation
	The displacement vector from origin to destination.

Detailed Description

Represents a 2D ray defined by an origin point and a translation vector.

Note

Use fromPoints() to conveniently construct a ray from two points. The translation is computed as (end - start).

Member Function Documentation

endPoint()

Vec2 endPoint ( ) const

inline

Returns the end point of the ray.

Returns

The computed point (origin + translation)

fromPoints()

Ray2D fromPoints ( const Vec2 & start, const Vec2 & end )

inlinestatic

Construct a ray from two points.

Parameters

start	The origin of the ray
end	A point used to compute the translation (end - start)

Returns

A Ray2D instance with origin and translation
