This application demonstrates a client-server web application which uses STK Components on the server to perform analysis, and Cesium Analytics SDK on the client (in a web browser) to visualize the results of that analysis using CZML. It also includes demonstrations of each of the specialized graphical features available in Cesium Analytics SDK.
To simplify the application and minimize dependencies, this application uses [Jetty][https://www.eclipse.org/jetty/] and [Spark][https://sparkjava.com/] to create a simple web service. Please note that use of STK Components, and the capabilities being demonstrated, are not specific to these frameworks. STK Components can be integrated with Cesium Analytics SDK using any web application framework.
The application also contains a small custom user interface to make it easier to explore the visualizations. This user interface is built using Knockout.js because it is already included in Cesium. As above, note that the capabilities being demonstrated can be used in any front-end framework.
This example demonstrates visualizing various types of Components objects and analysis, and the advanced graphical capabilities of Cesium Analytics SDK, including:
- A satellite propagated from a TLE
- Access between a satellite and a ground station
- Using a link to target a satellite from a ground station
- An aircraft propagated from waypoints
- Azimuth-elevation mask visualization
- Access between an aircraft and a ground location constrained using a azimuth-elevation mask
- glTF 3D models for the satellite, facility, and aircraft
- Satellite orbit paths and aircraft flight paths
- Vectors showing the body axes of the satellite and the Sun vector
- Sensor volumes on a ground station and an aircraft, a sensor dome, and a rotating sensor
- Dynamically changing a glTF model based on analysis, to rotate the solar panels of the 3D satellite model to point at the sun
This example requires Cesium Analytics SDK, which is included with an STK Components license, and can be downloaded from AGI's download site.
Unpack the contents of the Build\Cesium directory from the Cesium Analytics SDK package into the CesiumDemo\web\public\Cesium directory before building and running the example.
Then, to compile this sample application with Ant:
- Copy your AGI.Foundation.lic file into the src directory.
- Run "ant package".
The application will be compiled, packaged into a jar, and placed in the dist directory. You can then double-click the CesiumDemo.jar file to run the application, or, simply run "ant run".
Then, connect to http://localhost:4567 in your browser to run the application.
