There is an easier way to do an ellipse:

#declare majorVector = vnormalize(<1,0,0>)
#declare minorVector = vnormalize(<1,0.1,0>)

#declare majorRadius = 2;
#declare minorRadius = 1;

#declare CenterP = <0,0,0>;

#declare camT = 0;

#while ( camT < 1 ) // Goes from zero to one
  #declare thisT = camT * 2 * pi;
  #declare camPos = CenterP + (cos(thisT)*majorVector*majorRadius) +
(sin(thisT)*minorVector*minorRadius);
  sphere { camPos 0.1 pigment { rgb 1 } finish { phong 1 } }
  #declare camT = camT + 0.1;
#end

----
Well, maybe not so easy. What other shapes were you interested in?
