There is no direct way, to get a rack-gear spline from the given tools in C4D, perhaps the Formula spline, but I have no idea at the moment what formula I could create to make it fit to the options given in the cogwheel.
When done, uncheck the Xpresso “enabled” checkbox.
As a side note, I had first a continuously rotation as exploration of the cogwheel, which distorted the shape. If you observe the Platonic object closely, you will see that it rotates slow, then fast, then slow, that finally allowed to explore the round wheel close enough to create the straight one.
Thanks a lot, mattrittman,
I had to look up this term as well, so far here in the US I haven’t even heart it in over a decade by now.
I have always the feeling, there must be something simpler or more intuitive, perhaps just something procedural…
The procedural below, I would call that, “Spline2Ani2Spline”, utilizes a simple but very effective option to convert splines into position tracks.
First we need a single element, the point number sets the needs for the frame number. Functions> Spline to Position Track
The Y value can be just repeated, the X value needs to be: Offset Repeat. Since there is no Z change, I deleted that track.
Now we have a direct option to use these position tracks to create a spline, or we can use MoGraphs Tracer for that, which might allow for some adjustments, point wise etc.
Matt, as mentioned above, the Rack needs to be based on the rolling movement of the cogwheel, and this results typically in more space than the teeth itself.
The idea was to find the simplest set up, to create something like a “Rack Blueprint Maker”
Oh wow using a Tracer object on the cog is quite clever! It really draws the exact configuration you’d need for the straight teeth. Haha I wish I was as smart as you Dr. Sassi! This is very helpful. Thanks again!
Thanks a lot, you’re welcome Matt, very nice of you.
My idea about creativity is, that it is the ability to connect unrelated things with each other, and after connecting such things, some of those will make sense in an before non-predicable way.
To do that, one has to fill his/her creative library: Playing, messing, exploring, taking apart, trying to break it, do anything agains the rules (i.e., art rules—not including law of course), etc.
Having a constant growing library established, we need then only to overcome the “That’s how it’s done!” and the even more horrible “I know that!” behavior, and arrive so at the “What if…” state. Anything else will works wonders after that. (…mostly!)
