Detailed Description

Ray can be mathematically defined as a point (the origin of the ray in space) and a direction.

Kanzi uses rays for resolving the input to find where in 3D space the user clicked.

Constructor & Destructor Documentation

Ray() [1/2]

kanzi::Ray::Ray ( )

inlineexplicit

Default constructor.

Initializes the ray components to identity, origin=(0,0,0) and direction=(0,0,0).

Ray() [2/2]

kanzi::Ray::Ray ( const Vector3 origin, const Vector3 direction )

inlineexplicit

Constructor.

Constructs a ray from point and a direction vector. Normalizes the direction vector.

Parameters

origin	The origin of the ray in 3D space.
direction	The direction of the ray. The method normalizes the value before storing the value.
