Good to hear that it’s working perfectly now! I see that you already found the other thread, I suppose I should post a link for anyone else whom might come across this
A way to orient and place Frustum outline
Ya I was confused for awhile as well. I wrote in the other thread about making the geometry creation as generic as possible, then place & orient using the primitive. I suspect Cesium.Transforms.headingPitchRollToFixedFrame isn’t working properly, but I want to first make sure I’m using it correctly before I submit an issue.
