Types

type Model

type Model struct {
	Camera  world.Camera
	Root    *mechtree.Node
	Inbuilt SolarSystemModel // An inbuilt model that works without the internet.
	Scale
}

Model of the Solar System.

func NewModel

func NewModel(t celestial.JD, in solsys.Interval) Model

NewModel constructs a new Solar System animation Model.

type Scale

type Scale uint

The Scale may change to that which is better for showing either the inner or outer planets.

type SolarSystemModel

type SolarSystemModel struct {
	PlanetOrbits   []mech.Depictioner
	PlanetOutlines []mech.Depictioner
	SunOutline     mech.Depictioner
}

SolarSystemModel is a model of the Solar System including the orbits and outlines of the nine planets.

func NewSolarSystemModel

func NewSolarSystemModel(t celestial.JD, in solsys.Interval) *SolarSystemModel

NewSolarSystemModel constructs a new SolarSystemModel.

func (*SolarSystemModel) Update

func (mdl *SolarSystemModel) Update(t celestial.JD, in solsys.Interval)

Update the Solar System model.
