Digitize points using OpenGL

Purpose
This sample demonstrates how to draw on the globe using the OpenGL plug-in. It shows how to implement display feedback (drawn as a response to mouse events), as well as information that gets stored in a user-defined data structure. This sample focuses on listening to globe events; creating OpenGL display lists and textures; and translating, scaling, and bill boarding items.

How to use

See How to use ArcGIS samples for help on running the sample.

  1. Run the sample.
  2. Click the Digitize Points tool on the toolbar.
  3. Click and drag points on the globe surface. When you release the mouse button, a billboard icon is added at the mouse position.

If you installed the samples feature, you will find the files associated with this sample in <Your Developer Kit install location>\DeveloperKit10.4\Java\Samples\ArcObjects.

globe/DigitizeGlobeApplication.java
(view code)
 Class that creates the graphical user interface (GUI) for the sample.
globe/DigitizeTool.java
(view code)
 Class that represents a tool that attaches a globe display event listener that draws on the surface of the globe using the Java OpenGL (JOGL) application programming interface (API). The event listener uses the AfterDraw events to draw billboards at digitized locations. The event listener also provides feedback by drawing a circle when the mouse button is pressed.
globe/ImageTexturizer.java
(view code)
 Class that reads the compass.gif image file and returns a byte representation that can be used with the JOGL API to draw the image on the map.



Additional Requirements
  • When importing this project into Eclipse, you must also import the jogl_libraries project under $ARCGISHOME/java/samples/engine/lib, which provides the necessary JOGL Java Archive files (JARs).
  • When running the sample, you must provide the Djava.library.path=<path_to_jogl_bin_folder> VM argument. The value of this argument depends on the operating system you are using. For Windows, it will be similar to <ARCGISHOME>/java/samples/engine/lib/jogl-libraries/jogl-1.1.0-windows-i586/bin.
