Methods

equal

equal(b: Ray): boolean

- Defined in @types/Gjs/Graphene-1.0.d.ts:1976
Checks whether the two given #graphene_ray_t are equal.

Parameters
- b: Ray
  
  a #graphene_ray_t
Returns boolean

free

free(): void

- Defined in @types/Gjs/Graphene-1.0.d.ts:1980
Frees the resources allocated by graphene_ray_alloc().

Returns void

get_closest_point_to_point

get_closest_point_to_point(p: Point3D): Point3D

- Defined in @types/Gjs/Graphene-1.0.d.ts:1986
Computes the point on the given #graphene_ray_t that is closest to the given point p.

Parameters
- p: Point3D
  
  a #graphene_point3d_t
Returns Point3D

get_direction

get_direction(): Graphene.Vec3

- Defined in @types/Gjs/Graphene-1.0.d.ts:1990
Retrieves the direction of the given #graphene_ray_t.

Returns Graphene.Vec3

get_distance_to_plane

get_distance_to_plane(p: Plane): number

- Defined in @types/Gjs/Graphene-1.0.d.ts:1998
Computes the distance of the origin of the given #graphene_ray_t from the given plane.

If the ray does not intersect the plane, this function returns INFINITY.

Parameters
- p: Plane
  
  a #graphene_plane_t
Returns number

get_distance_to_point

get_distance_to_point(p: Point3D): number

- Defined in @types/Gjs/Graphene-1.0.d.ts:2008
Computes the distance of the closest approach between the given #graphene_ray_t r and the point p.

The closest approach to a ray from a point is the distance between the point and the projection of the point on the ray itself.

Parameters
- p: Point3D
  
  a #graphene_point3d_t
Returns number

get_origin

get_origin(): Point3D

- Defined in @types/Gjs/Graphene-1.0.d.ts:2012
Retrieves the origin of the given #graphene_ray_t.

Returns Point3D

get_position_at

get_position_at(t: number): Point3D

- Defined in @types/Gjs/Graphene-1.0.d.ts:2018
Retrieves the coordinates of a point at the distance t along the given #graphene_ray_t.

Parameters
- t: number
  
  the distance along the ray
Returns Point3D
