Location Line of Sight

This sample demonstrates how to perform a line of sight analysis between two points in a SceneView.

How it works

A LineOfSight analysis is a type of visual analysis you can perform on a scene. The LineOfSight analysis aims to answer the question: 'What are the visible and obstructed portions of a line between two locations?'. The output is a line, in an overlay, with two different colors - one representing visible areas, and the other representing obstructed areas.

1. Create a LocationLineOfSight, and assign values for the observerLocation, and targetLocation.
2. Once the LocationLineOfSight is created, add it to an AnalysisOverlay, and add the AnalysisOverlay to the SceneView.
3. The first screen tap, sets the observerLocation.
4. Each subsequent screen tap, sets the targetLocation and creates a new LocationLineOfSight.
