SimpleKeplerOrbits

Description

Unity3d project for simulating simple orbits using 2-body solution model.

Importing

This repository contains the entire Unity Project for basic demo setup. There are several ways to import the project:

• Manually copy all files from Asset directory to your unity project directory;
• Import asset store package;
• Import of the 'src' branch as embedded package.

Usage

This plugin has the ability to customize orbits using the editor inspector and scripts. Some scripting 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();
