Spatial Trochoids (almost)
In my extra time I've been developing a processing like IDE for graphic apps using the HTML Canvas element and javascript. It's not quite finished, but I've been using it to code several experiments as I learn javascript. Below is a link to my latest play, 3D spline curves built on a pseudo trochoid. The shapes are usually a mess because it's not really a trochoid (which always has a symmetry). While fiddling with this though I think I figured a way to generate true 3D trochoids. I just need to brush up on my quaternions and matrices then I'll have a symmetric version of this app. Anyways, here's the app...
• • run kilter • •
I need to put the app on a separate page because my current javascript uses global variables. I could put the app here in the blog post but if I wanted to put another the variables would conflict. I'm working on making the apps fully self contained so you could put them wherever, that'll be nice.

browser trochoids
• • see my test • •
Trochoid app for a browser? I've tried java and flash which worked well but didn't excite. Now I discover this newish html thing called a Canvas that javascript can draw into. I like it. This is my first test of the Canvas to see how fast it can draw.

laser spins
the setup...
...swing it about and record a time lapse photo of the light trace. Experimented with weights in various positions along the string, swing style and exposure lengths from 8 to 64 seconds. Conclusion: traces seem pretty random, I was hoping for more of a basin of attraction. Will continue search.

Trochoid Apps for download
I've made 3 trochoid based apps, they are: Trochoid, TroTorted and circa. These are mac apps and should run on intel or powerpc. Should run on 10.5, I'm running 10.4 and they may run as far back as OS9 with InterfaceLib and CarbonLib installed!
These are the apps I use to create all the spirography images here. The apps are freeware. Trochoid was initially shareware and water marks movies and restricts rendered image sizes until registered. To unlock that goto Trochoid Preferences...->Enter Registration->put "wuve-khmn-ooru" into the code field and press enter.
Documentation is lacking for all the apps. Lacking as in there is none. Years ago I made some unfinished documentation that I'll try to find and repost. For now my intentions for more and complete documentation is to make videos. The video below is my first. It doesn't explain much but shows the general path from start to finish of making a trochoid movie.
Download TrochoidApps.zip 6MB
what you get...
The downloaded file 'TrochoidApps.zip' expands to the folder 'Trochoid Apps (raw)'. (raw means there are no sample files :( yet) Inside you'll find Trochoid, circa and a folder for TroTorted.
TroTorted is in it's own folder because it needs to be next to the Quesa file. Quesa is a 3D engine. If TroTorted can't find Quesa it'll crash while trying to start. (circa uses Quesa too, but I was able to package it inside the app)
Trochoid
Build, animate, texture and render. The most complex of the 3. The interface is non-standard and I don't know how intuitive it is. Most in need of documentation/how-to's.
circa
Build curves. The main feature of this app is that the curve is 'live'. You can adjust the rotation speed while it's in motion. In Trochoid you can't change the parameters while the animation preview is running. This app has no color and texturing is very limited. It was designed primarily to explore curve motion.
TroTorted
2D trochoid curves are wiggled in the third dimension by a sine wave. 3D mesh models can be output as DXF or for POV-RAY.
Again, I need documentation and sample files. That will be my next post. Enjoy :)

Trochoidal Videos
This first video shows the process of making a rendered movie. About 40 minutes of computer time is compressed to 2 minutes.
These next 3 videos repeat the same animation 4 times to simulate some looping.
The last video is available in this MUCH higher quality file: springs3z.mov.
640x480, 29.97fps, ~12 seconds, looping, quicktime, 8.7mb
