Surface properties expressions


This sample demonstrates how to update the orientation of graphics in graphics overlay using expressions on scene properties. Move the Heading and Pitch sliders to change the orientation of graphics in the graphics overlay.

How it works

The sample creates an AGSSimpleRenderer object for graphics overlay. On the renderer the sceneProperties.headingExpression and sceneProperties.pitchExpression properties are set to the attribute names, on the graphics, used to change the values for heading and pitch. Each slider affects the value of respective attribute, which in turn affects the orientation of the graphics via the renderer.
