Sidetracked

Filed under: Uncategorized — SirGolan @ 12:16 pm

I finished up integrating Axiom into MV3D and had most of it actually working. Fitting it in was pretty hard, and in the end, it turns out it actually won’t work for the main simulation part of things. It’d be fine for accounts, realms, directories, and asset descriptions– all things that are fairly static. In any case, I’m taking a break to decide how to proceed.

Instead, I’ve been working on something all together different. There have been some videos going around on how to use the wiimote for various things like head tracking, a virtual whiteboard, etc. I’d been sort of thinking of making a wiimote and writing some software to do the tracking, and then saw this. It is in Python, and it was easy for me to get working with my webcam and stuff. But looking at the code, it needed some help, and only single point tracking was working with a reasonable (>4fps) framerate. No problem. I started over on the tracking code and have multipoint 2d tracking working at about 50fps (faster than my webcam can dish out frames). I added dual webcams (crappy, but who cares for this use) from radioshack for $15, along with an assortment of IR LEDs and a valiant floppy disk that gave its life to become a !IR filter. So far, I’ve only gotten two point tracking (like the wiimote’s sensor bar), but 3 point is just a little bit of trig away. :)
Anyway, I have no idea what I’d ever use this for, but it’s fun to play around with– especially hooking it up to Ogre for 3D tracking.
