3D Across the Platform

A new way of working in 3D

ArcGIS 3D Components

3D Application Development

3D Runtime SDK• Full 3D Runtime functions• High performance• Large data set• Machine Native code• Mobile and desktop• Multiple codebases

JavaScript (WebGL)• Pure browser-based• No plugin• Rapidly maturing• Acceptable performance• Works on most platforms• One codebase

ArcGIS API for JavaScript 4.0

• One API for 2D and 3D• Now in beta 3

• Elevation

• 3D symbology

• Camera manipulation

• Animation

• Lighting/shadow

Supported Real-Time Data

• StreamLayer (from GeoEvent Stream Service) – JavaScript API 4.0• KML

Real-Time GIS2

Real-Time GISIntegration and exploitation of streaming data

• Integrates real-time streaming data into ArcGIS

• Performs continuous processing and real-time analytics

• Sends updates and alerts to those who need it where they need it

SpatiotemporalBig Data Store

Enhanced Map and Feature Service

• Can ingest higher velocity real-time data into ArcGIS.

• Observations CAN now be stored in a Big Data Store.

• Can visualize high velocity and volume data

- as an AGGREGATION,- as discrete FEATURES,- live & HISTORICALLY.

• Visualization CAN scale.

Making 3D Scene Comes Alive4

Two patterns of Real-time GISStream services vs. traditional feature services

• Feature layers pull from feature services- Web apps poll to get periodic updates

• Stream layers subscribe to stream services - Web apps subscribe to immediately receive data- Low latency and high throughput

Two patterns, two important differencesStream services vs. traditional feature services

• Feature services persist their data in a Geodatabase

• Stream services broadcast their data without first persisting the data

What can I use to consume stream services?Support for stream services in the 10.3 and 10.3.1 product releases

• Not available out-of-box!• Obtain the KML Connector for GeoEvent on GeoEvent Gallery (10.2.x)

http://www.arcgis.com/home/item.html?id=8ddf65e2d9894d37ae19856671392c45

• Obtain source code from GitHub (updated to 10.4) and build ithttps://github.com/Esri/kml-for-geoevent

• Deploy the jar to GeoEvent\deploy folder• Create Output

Demo Publishing Real-Time Services

Real-Time 3D Visualization5

• 3D scene contains continuous scale - depending on the positions of viewer and target

• Use high LOD 3D symbol to represent objects close to the viewer• Use low LOD symbol for objects that are further away from the viewer

- Billboard 2D graphics- Simple geometric shape (e.g. spheres)

• Remove objects that are too close or too far from the scene- Use view volume culling- Use fog (particle system)

Conclusions6

Conclusions

• Time enabled 3D applications for mobile and web can be developed using ArcGIS components

- 3D Web Scene, ArcGIS Explorer, ArcGIS Earth- GeoEvent to handle real-time data- JavaScript API for ArcGIS version 4

• Visualization of large volume of data in 3D needs certain techniques for good performance

• JavaScript API version 4 is in beta 3- More functionality are being added
