Tom's POVRay Disc Magnet

The picture above was made with this demo POV file and this magnet object POV file

About this Object

This is two objects, one is the magnet, and the other is the paint around the magnet. This allows you to chip the paint (by subtracting out a sphere or other shape) to show the unerlying magnet. The real magnets I based this on had thick paint, and several of them had chips around the edges.

I even modelled the little divet on the underside of the magnet. The colors used in the image are also close to the real magnet colors.


The magnet is oriented to stick to a wall in the X-Y plane at Z=0, protruding out in the -Z direction, and is centered around the Z axis. This is shown in the top magnet in the picture above. The magnet body is 0.75 units in diameter, and protrudes 0.22 units in the -Z direction from the "wall". The paint extends beyond this 0.005 units, past both the top and the sides.

Problems and Future Work

I suppose I could make the chipping automatic and random, with a way to turn it off or on, and to make it a little or a lot.
