Tom's POVRay Push Pin

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

About this Object

Based on the common plastic-headed push-pins that we see everywhere. The shaft of the metal pin extends inside of the plastic, and has a flat head on it, which is all visible if rendered semi-transparent (as some of these push pins are sold).


The axis of the pin lies on the Z axis, with the pin pointing in the positive Z direction. The origin goes through the joint between the metal pin shaft and the plastic pin top, so that it appears pushed all the way into a plane at Z=0 (hint for using in scenes, pushpins are never quite pushed in all the way, and they're never pushed in completely straight).

The pin point is 3/8 units past the origin in the postive Z direction, and the top of the plastic is 0.465 units in the negative Z direction.

Problems and Future Work

The spherical dome that sits on the top of the pin does not perfectly match up to the cone it sits on top of.
