3D View

The 3D view Viewpoint type allows users to configure an output window displaying the desired objects in a three dimensional view focused on the desired object. A View command can be used to generate a 3D view, or a ViewWindow object with a 3D view Viewpoint can be used. The following is a list of the configurable options for a 3D view Viewpoint.

•Reference Frame

•Source

•Target

•Tail Reference

•Right Ascension

•Declination

•Radius

•Field of View

To create a 2D or 3D Mission View centered on a central body other than the Earth, including custom Celestial Objects, create a ViewWindow and edit the Viewpoint Source and Target properties. The positions of the built-in CelestialObjects (planets, sun, and moon) are determined by the planetary ephemeris defined in your User Preferences.

The script example below shows how to create a 3D View Viewpoint focused on a Spacecraft with the Earth as the tail reference, and add it to a ViewWindow.

// Create 3D Viewpoint

Viewpoint ThreeDViewpoint;

ThreeDViewpoint.ViewpointType = "view";

ThreeDViewpoint.ViewpointName = "Spacecraft View";

ThreeDViewpoint.ThreeDView.ReferenceFrame = "inertial";

ThreeDViewpoint.ThreeDView.Source = Spacecraft1.ObjectId;

ThreeDViewpoint.ThreeDView.Target = Spacecraft1.ObjectId;

ThreeDViewpoint.ThreeDView.TailReference = Earth.ObjectId;

ThreeDViewpoint.ThreeDView.RightAscension = 45;

ThreeDViewpoint.ThreeDView.Declination = -10;

ThreeDViewpoint.ThreeDView.Radius = 10000;

ThreeDViewpoint.ThreeDView.FieldOfView = 45;

// Add Viewpoint to a ViewWindow and activate it

ViewWindow ViewWindow1({Spacecraft1});

ViewWindow1.AddViewpoint(ThreeDViewpoint);

ViewWindow1.ActivateViewpoint(ThreeDViewpoint.ViewpointName);

Update ViewWindow1;
