Calculate Distance 3D

Demonstrates how to calculate the distance, in meters, between two Graphics in 3D space.

How it works

To calculate the distance between two Graphics in 3D space:

  1. Create a GraphicsOverlay and attach it to the SceneView.
  2. Create the two graphics and add to graphics overlay.

    • supply each graphic with a Point, starting location, and SimpleMarkerSymbol

  3. Convert each graphic's point to the Cartesian coordinate system
  4. Create a JavaFX Point3D from the Cartesian x,y, and z value.
  5. Then get the distance between each of the JavaFX Point3Ds, Point3D.distance(Point3D).
