Types

type Ray

type Ray interface {
	Origin() *vec3.Vec3Impl
	Direction() *vec3.Vec3Impl
	PointAtParameter(t float64) *vec3.Vec3Impl
	Time() float64
}

Ray defines the methods used to work with rays.

type RayImpl

type RayImpl struct {
	// contains filtered or unexported fields
}

RayImpl implements the Ray interface.

func New

func New(origin *vec3.Vec3Impl, direction *vec3.Vec3Impl, time float64) *RayImpl

New returns a new ray with the supplied origin and direction vectors and time.

func (*RayImpl) Direction

func (r *RayImpl) Direction() *vec3.Vec3Impl

Direction returns the direction vector of this ray.

func (*RayImpl) Origin

func (r *RayImpl) Origin() *vec3.Vec3Impl

Origin returns the origin vector of this ray.

func (*RayImpl) PointAtParameter

func (r *RayImpl) PointAtParameter(t float64) *vec3.Vec3Impl

PointAtParameter is used to traverse the ray.

func (*RayImpl) Time

func (r *RayImpl) Time() float64

Time returns the time associated with this ray.
