Hi,


For a cylinder along the x axis, the equation is :
	function { y*y + z*z - R }

Ok, but how to make an isosurface cylinder like povray cylinder from two 
points?


I thought to :
  - compute distance from p2 to p1.
  - compute the two angles from p1 to p2
  - make x axis isosurface cylinder
  - rotate the isosurface of the two angles
  - translate to p1

Do you see a simpler solution ?
