Hi everyone. First of all congrats for this great webgl framework. I am a c# programmer, and rather new to javascript world, but I had really no problems in using Babylon.js following your tutorials. In order to train with webgl i am actually creating a scene which represents the Solar System. I am stucking about which mesh should i use to draw Saturn Rings. What i need would be a sort of 2D circle, with external and internal radius property, but i wasn't able to find such a mesh. Cyclinder would be ok, defining heights to 0, but i can't define an internal radius. Torus looked ok at first, but i cannot deal with thickness properties in order to make a torus looks like a 2D ring. Does anyone has any advice ?
