Prerequisites

Steps

Create a new Java project with Gradle

1. Open IntelliJ IDEA.

2. From the Welcome to IntelliJ IDEA screen, click the New Project button. (If you're already inside a project, click File > New > Project in the menu bar.)

3. In the New Project window, do the following:

   • Enter a name for your new project and choose a location to save it. Your app name can contain only Latin characters, digits, _ , - and :.

   • Deselect Create Git repository, if necessary

   • Select Java as your programming language, if necessary

   • Select Gradle as your build system

   • Select a supported JDK

   • Select Groovy as your Gradle build language (i.e. DSL), if necessary

   • Check the Add sample code box, if necessary

   • Click Advanced Settings to expand the drop-down. Set the Gradle distribution to Wrapper and check the Auto-select box for the Gradle version. Optionally, you can enable or disable the ability to use these settings for future projects. For GroupId enter com.example.app. You can leave the default for ArtifactId.

   • Click Create to build your new project.

4. In the Project tool window, replace the contents of the build.gradle file with the following script to configure your app and reference the API. Make sure that you load the gradle changes after modifying build.gradle.

   More info

   To load the Gradle changes, in the Gradle window, click the Reload All Gradle Projects icon in the upper left corner.

   wrapper {
       gradleVersion = '8.10.2'
   }

5. Click View > Tool Windows > Gradle to open the Gradle view, then in Tasks > build, double-click copyNatives. This unpacks the native library dependencies to $USER_HOME/.arcgis.

   More info

   You can also run Gradle tasks via the command line. Consult Gradle's documentation to learn how this is done.

6. In the Project tool window, under your package com.example.app, right-click Main and click Refactor > Rename....

7. Rename the Java class to App and click Refactor.

Add import statements

1. In App.java, add import statements to reference the ArcGIS and JavaFX classes.

Add a UI for the scene view

A scene viewA scene view is a user interface that displays scene layers and graphics in 3D. It uses a camera to control the visible area of the scene and supports user interactions such as pan, zoom, tilt, and rotate.Learn more is a UI component that displays a sceneA scene is a collection of layers that are displayed in 3D. It is typically composed of a basemap layer, data layers, and 3D data.Learn more. It also handles user interactions with the scene. Use JavaFX to add a scene view to the UI.

1. In App.java, define a class named App that extends the JavaFX Application class.

   • Add a private member variable for a SceneView.

     More info

     The sceneView member variable allows you to easily reference your SceneView from other parts of the application.

   • Inside the main() method, replace the print statement with a call to Application.launch(args).

     More info

     This code calls the static method launch() of the JavaFX class Application, which creates an instance of your App class on the JavaFX Application Thread and then calls the start() method. For a description of the JavaFX life-cycle, see Application.

   • Override the start() method, in which you configure the JavaFX Stage with a title and dimensions, and then show it.

     More info

     Note that the start() method is abstract in the JavaFX Application class and must be overridden in your application code. The start() method takes a single parameter of the JavaFX type Stage.

   • Create a JavaFX StackPane, and use it to create a JavaFX Scene. Then set the scene on the stage.

3. Create a new Surface and add a new ArcGISTiledElevationSource to it to define the base surface for the scene. Next, set the setElevationExaggeration property on the surface to 2.5f to increase the 3D effect of the elevation. Finally, set the surface as the base surface of the scene.

   More info

   An elevation source can define a surface with 3D terrain in a scene. Without an elevation source, the default globe surface is used to display the scene.

4. Set the initial viewpoint of the sceneView using a Point and a Camera.

   More info

   The position you view the scene from is defined by a Camera. The following properties of the camera are used to define an observation point in the scene:

   • 3D location: Latitude, longitude, and altitude
   • Heading: Azimuth of the camera's direction
   • Pitch: Up and down angle
   • Roll: Side-to-side angle

Get an access token

You need an access tokenAn access token is an authorization string that provides access to secure ArcGIS content, data, and services. Its capabilities are determined by the privileges it supports. It is obtained by implementing API key authentication, User authentication, or App authentication.Learn more to use the location servicesArcGIS Location Services, also referred to as Location Services, are services hosted by Esri that provide geospatial functionality for developing mapping applications. They include the ArcGIS Basemap Styles service, ArcGIS Static Basemap Tiles service, ArcGIS Places service, ArcGIS Geocoding service, ArcGIS Routing service, ArcGIS GeoEnrichment service, and ArcGIS Elevation service. An ArcGIS Location Platform or ArcGIS Online account is required to use the services.Learn more used in this tutorial.

Modularize the app

A Java module adds a higher level of aggregation above packages. A module must provide a module descriptor that specifies the dependencies, the packages the module makes available to other modules, and more.

You will create the module descriptor for this project in a file named module-info.java.

1. In the Project tool window, under src/main, right-click the java folder, and click New > module-info.java.

2. Inside module-info.java replace the module name (i.e. highlighted text) with com.example.app.

3. In the body of the module descriptor, define the three required packages this application depends on: com.esri.arcgisruntime, javafx.graphics, and org.slf4j.nop.

4. Export this project's module package to make it accessible to code in all other modules.

Run the app. Ensure to run the app as a Gradle task and not as an application in your IDE. In the Gradle tool window, under Tasks > application, double-click run.
