Spur gears

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.

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

Gear 2D Prototype

Following the circle involute blog, I thought about creating a gear procedure for easy creation of different gears. The method used is quite differnt to the involute idea but the turtle geometry way of thinking and doing the gears. This prototype procedure utilised a simple regular poygon formula (repeat :sides [ fd 1 rt 360/:sides ]) and some built-in commands such as TOWARD and SETHEADING to rotate the turtle and get the directions needed.

Palm Tree Leaf

Outsite my office window, there are many palm trees. I thought about making one so it may be reused later to make a full tree.

circle involute

As part of a project to make a nice gear mesh with logo, I wondered how to generate the involute of a circle.
