i'm using camera3b.pov and camera3d.pov which come with pov as the basis
for my tests.  i have changed the camera to read as follows:

camera {
  cylinder 2  //as a comparison to type 4.
  angle 360   //i want total wrap around.
  location <0, 10, 0>  //middle of the object.
  right <15, 0, 0>  //long enough vector to poke out the end of the
cube.
  up <0, 6, 0>     //tall enough vector?
  direction <0, 0, 2.5>  //not sure what this does with
  look_at <10, 10, 0>  //this following it. notice i changed this.
}

i see what i expect; a curvy version of the cube thing and i can see all
of the sphere corners.  what i really want is to use cylinder type 4,
however the results are not what i expect.  what i expect to see is all
four corners with straight rods conecting them instead of the curved
ones from type 2.  all i get, however are four horizontal rods.  i don't
see any of the sphere-corners.  changing the right and up vectors has no
effect.

i am using the windows megapov 0.5a.
