How to get VertexArray or similar from a Cesium3DTileFeature

1. A concise explanation of the problem you’re experiencing.

I would like to know if it’s possivel to get the vertex points of a Cesium3DTileFeature, or triangle array ( since lineSegmentTriangle is provided), or a Cesium3DTileFeature’s point’s surface normal

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

I am trying to trace intersections and reflections of rays along any kind of obsticle (from globe surfaces and OSM buildings). There for, to get the angle of reflection, the normal of the surface intersected needs to be calculated

4. The Cesium version you’re using, your operating system and browser.

Cesium version: 1.89
OS: Windows 11
Browser: Chrome

Edit: Came across the experimental features for 3DTileFeature, is there a way to change the default value of the vectorKeepDecodedPositions to true so that the polylinePositions attribute is always available for every 3DTileFeature?
