  Thanks for your help, Steve. The link that you sent me too has taught



  However, there is still a couple doubts that come from the SOLID AND
EMPTY OBJECTS section in the POV documentation. In fact, it is
emphasized about the need to be careful when we have a camera inside a
non-hollow (solid) object. What difference does it make if the camera is
inside or outside? For example, if the object was solid but transparent,

expected. Am I wrong?

  Once more, thanks for your help!
