mc.pmpd/max/seriously confused

July 1, 2011 | 7:07 pm

Anyone in the NYC area feel like getting together and sorting this out for me? I understand what a msd system is. I even got msd3d working but I’m just completely confused about how mc.pmpd works. If you’re interested email me. I’ll gladly pay for tutoring.

hi

you have to created a group name with an id.

you can copy this (an exemple) on each object and change id (first mass id 1, second id 2,…..) :

mc.pmpd.mass2d tic @D 0.01 @XY 0.5 0.5 @Xmin 0. @Xmax 1. @Ymin 0. @Ymax 1. @M 5. @gr mass @id 1

if you want to make different group you have to change the name group (gr) and repeat the process.

"tic" be a bang receive, from the clock render for exemple

make the same for link object and other….

mc.pmpd.link2d tic @c1 mass.1 @c2 mass.2 @K 0.1 @D 0.05 @D2 0.05 @L 0.1 @show 1 @gr link @id 1

best

Hey oranoutan,
Believe it or not, I’ve got that too. What I don’t have is
A) how to fix certain masses so it doesn’t fall apart.
B) how to set a starting point for all the masses.
and C) how to get them to draw to the screen

I’m trying to write an abstraction that creates a cloth like this.

Attached is what I have so far.

hi

a) for fix mass : used argument @solo 1, for don’t fall apart you have to used a pmpd.iplane to define a limit space.
b) to send a start point to mass : used @XY Xposition Yposition (ex :@XY 0.2 0.2) or send setX {position} setY {position} on the right inlet
c) to draw on the screen you have to used a jit object like jit.gl.gridshape or other. you connect a jit.gl.gridshape to the rigth outlet of the pmpd.mass object. for draw masses or link you have to used @show 1

sincerely if you like to created a cloth like your link i advise you to used msd3D. it be more lighter if you used lot of mass and more easy and fast to construct a complex system. but you can’t have a bounds detection…

i have work on 2D sytem based on poly to managed complex system and generate lot of mass with pmpd, i actually work on a 3D system but not ready now. I can informed you when he’s ok…
