Interested in tutorial on how to achieve table-top view of Cesium in AR (with Hololens)

Hi team! I’ve been struggling trying to achieve a table-top view of the Cesium world specifically for Hololens (as in the demo shown a while back).

In the demo, using Unreal’s MRTK for Hololens, it shows a view of the world scaled and manipulated in augmented reality (zooming in/out and dragging the map within the confines of a table). I’ve tried playing with the GraphicsTools from Microsoft (using the Clipping Primitives system), but sadly have not been able to achieve the desired results.

My assumption is after I can effectively clip out all terrain outside a box, I would need to reorient/scale the CesiumWorldTerrain actor to align the world surface to synchronize with a “table-top” surface in world-space? Absolutely stumped how you got that to work.

Would make for a GREAT tutorial… :wink:

Hello,

You’re right - this would make a great tutorial. I’ll see what I can do, but it may be a little bit until I’m able to focus on it.

In the meantime, here are a few posts that may be able to help you out -

We’re also working on a spline-based clipping feature to clip out terrain. That feature is still in development, but may be helpful in your case - Clipping 2.5d by nithinp7 · Pull Request #446 · CesiumGS/cesium-unreal · GitHub
