In real life, it should be similar. Those edges are about parallel to 
the path of the particles whitch preclude particles from touching them.

As for the particles path, using the sine? Sould'nt you use the tangent 
of the angle instead? After all, the tangent is the function of the 
projection of an angle on a line/plane tangent to the circle/sphere, 

travel parallel to the line/plane in this case.
