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