you'll have to map your mouse x/y to your x and y controls on the wiipaint patch to move the blue dot around and the use the pen down control as the pen down on the wii patch but i forget how vdmx's tablet control works you might have to map a keypress to having a pendown/erase thing

How? within vdmx itself or within quartz. I know nothing about quartz and would be very thankful if you could point me in the right direction as to where to start. Im so lost, a step by step instruction would be nice, but you dont have to take the time, just link me to some tutorials or something would be great. thanks.

load the wiipaint qc patch up as a movie in vdmx and then in the layer controls it has some controls for x and y position (as well as pointer color, decay, feedback, pointer size.) right click/control click the x and y controls and assign them to the mouse x and y or something that moves around..sorry i cant really provide more instruction than that

Can I use the wiimote without the ir sensor to draw with this patch? Also, how can I set the x and y once I have the patch loaded in vdmx?

Thanks!

it's pretty much impossible to get reliable x/y data from the wiimote without use of the ir. you can make your own ir sensor by just using two candles though.

to connect the wiimote to the x/y slider, just make sure the wiimote is paired correctly in vdmx, and then set the datasource of the sliders to the corresponding ir data of the wiimote.

btw if someone has managed to get x/y reading without ir, i bow humbly and sing praises to your name, for you are then the god of all accelerometers. also, could i have your patch please Wink

This is by no means accurate, but still roughly controllable (and quite old)

Actually I have some ideas on how to make it a lot more reliable and will try and update it when I get a chance.

mac only I'm afraid.

hallelujah! glory be to thee, oh mighty memo. how blind was i to this infinite source of wisdom that is thy website Wink

weird thing, though. wii2midi fails to pair my wiimotes. while the kineme plugin, vdmx and osculator all pair up (as you see, i've tried a few avenues already).

i still have my mouth on the floor as to what you managed to do though... any chance i could have a look at the math going on under the hood?

Thanks, but its actually not as complicated as it looks Razz

You can find the source at http://mike.verdone.ca/wiitomidi/

Mike Verdone wrote the app - I just added this position/velocity info - and he maintains the site etc - and he hasn't updated it in over a year - which is probably why it doesn't pair (the connection uses the DarwinRemote framework which has been notoriously buggy, many improvements have been made this past year in connecting wiimotes, and wiitomidi hasn't been updated with any of those improvements). Saying that, I can connect with wiitomidi no problems... its just real sketchy I guess.

What I want to do is write a processing app which does the same thing, so its cross platform... and instead of using Euler integration (which is real cheap and dirty and not accurate), use 4th order Runge Kutta which I'm hoping will give more accurate results. But on the other hand, months ago there was the announcement of that iittle addon to the wiimote which would provide one-to-one mapping which would make this thing obselete. It is supposed to be a bit expensive, but does look pretty sweet.

thanks a lot!

it's great to have x/y functionality in the wii's current incarnation, without the use of the ir, methinks. for a 40 euro controller it has so many output options, all at a price for which i can't solder it together. it's only the ir that always bites me in the ass in any environment other than the sterile test lab. ('excuse me, could you extinguish all lights, cigarettes, and generally not radiate any heat at all, so i can make this toy work?')

Actually I was trying to fake-read the position of the wiimote by integrating the accelerations - which is a bit of a paint. But there is a much easier way to use the wiimote for painting without using IR - by using the orientation of the wiimote. OSCulator outputs the wiimote orientation, and you can use those to move a virtual paint cursor - or even simpler you can just use the x acceleration and y acceleration and control them by rolling and tilting the wiimote. I've got a patch working quite nicely, but can't log into my site for some reason right now, so will post it tomorrow hopefully. P.S. Works quite well with the iphone too Razz

The WiiMote plugin in VDMX also outputs the orientation and it has really nice controls for offsetting and clamping the range of orientation you want to work with. Not as easy to use for painting as IR but thats expected

cheers

yea you definitely don't have the precision for painting with orientation v.s. IR, but it can still be fun. Its probably easier to set it up in VDMX compared to QC, but I uploaded my comp anyway... I also added painting with iPhone orientation too Razz
