smoother tooth

Trying to get a smoother appearance for the curved gear teeth involves lessons both in logo programming and in the underlying 3d display technology.

3 helical gears

The real advantage of gear modelling in 3d is that gears in a mesh do not have to parallel each other. It is posible to demonstrate how gears can transfer rotation (and forces) to orientations other than the driving gear. This kind of transfer is possible by use of helical gears.

3d gears

As an update to the 2d involute (curved teeth) gears, I modified the program to produce 3d (extruded) gears. This required a change in drawing tactics.

Spur gear set

Finally, not perfect at all but working gear set in 3D. Thanks to asplech's blog about involute gear and this Spur Gear document, I finally get to know better about these cogged wheels.

two gears

It turned out that producing a set of involute gears requires quite a bit of geometry in addition to involutes.
