Can TextSymbol graphics be draped on 3D SceneView?

GaryLSheppardJr — Mon, 22 Nov 2021 15:07:02 GMT

I'm using the ArcGIS API for JavaScript 4.20. I'm adding point graphics and text graphics to a 3D scene view, using GraphicsLayer and TextSymbol. It's working well. But the text graphics are always billboarded, even if I use the on-the-ground mode for the graphics layer. Point graphics honor the mode, displaying draped if the mode is on-the-ground and billboarded if the mode is relative-to-scene.

Is there a way to get text graphics to drape on the 3D scene instead of billboarding?

Have you tried TextSymbol3DLayer?

hi @GaryLSheppardJr

It is not supported to drape text graphics on the ground.
I wonder what's the use case to not have them billboarded?

Hi Noah. I tried it but the text graphics are still billboarded. I don't see a way to make them draped.

To make a simple example, I modified the Add Graphics to a Scene View sample. Here's what I got: https://codepen.io/gary4620/pen/rNGeMeb

My symbol code in the sample:

const markerSymbol = { type: 'point-3d', symbolLayers: [{ type: 'text', text: 'The Text', material: { color: '#ffffff' }, size: 50 }] };

Thanks, Sascha, for confirming that it's not supported. I don't know what the use case would be, but I wanted to ask in case my customer asks if the text can be draped. I don't have a specific need for this capability yet.
