SimpleKeplerOrbits

Description

Unity3d project for simplest orbits simulation, using 2-body solution model.

Importing

This repository contains whole Unity Project for basic demonstration setup. There are multiple ways of importing project:

Manual copying of all files from Asset directory to your unity project directory;
Importing asset store package;
Importing 'src' branch as submodule, which contains only Assets folder content.

Usage

This plugin has the ability to customize orbits using the editor inspector and scripts. Scripting is fully optional. Some usage examples:

Initializing orbit from orbit elements (JPL database supported)

	var body = GetComponent<KeplerOrbitMover>();
	body.AttractorSettings.AttractorObject = attractorTransform;
	body.AttractorSettings.AttractorMass = attractorMass;
	body.AttractorSettings.GravityConstant = GConstant;
	body.OrbitData = new KeplerOrbitData(
		eccentricity: eValue,
		semiMajorAxis: aValue,
		meanAnomalyDeg: mValue,
		inclinationDeg: inValue,
		argOfPerifocus: wValue,
		ascendingNodeDeg: omValue,
		attractorMass: attractorMass,
		gConst: GConstant);
	body.ForceUpdateViewFromInternalState();

Initializing orbit from orbit vectors

	var body = GetComponent<KeplerOrbitMover>();
	body.AttractorSettings.AttractorObject = attractorTransform;
	body.AttractorSettings.AttractorMass = attractorMass;
	body.AttractorSettings.GravityConstant = GConstant;
	body.OrbitData = new KeplerOrbitData(
		position: bodyPosition, 
		velocity: bodyVelocity, 
		attractorMass: attractorMass, 
		gConst: GConstant);
	body.ForceUpdateViewFromInternalState();
