I dream of a control mechanism in which the user is presented with a big rectangle. Inside can be placed an arbitrary number of "poles." These will be numbered and will correspond to outlets. When performing with this object, the user can click the mouse anywhere inside, and the euclidean distance from each pole will come out of the outlets.

This is somewhat akin to electrotap's color-based control scheme, but simpler and easier [possible?] to do on-the-fly.

1. Has anybody done this? I haven't seen it. Have you?

3. How would YOU do this? I can imagine a combination of LCD and javascript. It should be as lightweight as possible.

what a weird dream. even if you consider only one, standard sized pole, how 

if i got you wrong, you could try jsui object (which is something like 

lcd+javascript, but different), and here's non-javascript way to do it:

you could simply track the mouse in an lcd, and compare 

the mouse position with the current positions of pole 1,

pole 2, pole 3 ... then you can calculate the distance 

between pole 1 and mouse position and pole 2 and mouse 

position etc and compare those values to control gain

maybe you become the second person using [110.pythagoras]?

it was made for exactly this purpose.


hehe. I used it as well actually. Yeah, I was a bit lazy to remember 

my old maths courses and patch it myself... Shame on me.

i liked your patch nesa, could not resist messing with it. In the following sounds like 7 trucks parking up.

I think no javascript necessary here, paint each oval as sprite, track 

the position of each sprite, if clicked at a position of a sprite, 

select and move it with the mouse, do the distance calculation as nesa 

showed in his example. Should be reasonable light weight and straight

THANKS everybody. Sorry I ditched the thread for a few days.

nesa and john - great stuff. You guys have done the bulk of the work I was going to do. I'm going to make some improvements, make it a bit more generic and reusable, and I'll post back (maybe even add it to the max objects database).

I had been thinking of using vbap for this too. Seems overly complicated when plain ol' euclidean geometry works fine.

have a look at int.lib - sounds similar to what you guys are doing
