Another flat, finite object available with POV-Ray is the disc. The disc is infinitely thin, it has no thickness. If you want a disc with true thickness you should use a very short cylinder. A disc shape may be defined by:
- disc {
, <Normal>, Radius [, Hole_Radius] [OBJECT_MODIFIERS...] }
The vector <Center> defines the x, y, z coordinates of the center of the disc. The <Normal> vector describes its orientation by describing its surface normal vector. This is followed by a float specifying the Radius. This may be optionally followed by another float specifying the radius of a hole to be cut from the center of the disc.
