View Full Version : Curve Dynamics
NeptuneImaging 05-03-2005, 04:09 PM I have been trying to figure this out but is there a way to make a curve as a deformer for things like ropes and cables...
I am trying to make a rope deform freely as possible and using the CV as a softbody so when it dangles....it there a way to do this...
thanks :)

use syflex or cloth or any dynamic system on a grid, extract an isoparm of that grid as a curve and keep the relationship, do whatever you want with that curve.
you can also download string and rope operators from www.motionblur.it, but they will be realtime, therefore to get the correct timing and everything you will need to render or at least capture a viewport, as they're not cached and do not preserve a frame2frame state

Okay, I have extracted the curve with a clothOp and now want that extracted curve to act as a deformer....and I want a polygon cylinder to inherit the dynamic property of that curve. I have just tried Deform by curve and nothing happened...it just snapped to the location

Have you tried Deform by Curve with that cylinder and a simple, static curve? Perhaps you need to make sure it works in a simple scenario first, tweaking the parameters if necessary. I can't really think of a good reason why it shouldn't work...

Hey what's up...
I have tried the static curve, that works perfectly...but now I am doing an added bonus and using a soft body to deform the cylinder dynamically....

Okay, it seem to only work when I use a softbody....

You could try this Dynamic Spline script:

I haven't tested it, so I cannot vouch for it's usability.
Have u seen the RopeSim script by Kim Aldis?
From the website:
"A script that does a dynamic simulation of a piece of rope, constrained at both ends to either static or animated objects. It was originally designed as a method for constructing and animating rope harnesses that would interconnect large numbers of creatures - over 400 in the end - pulling a carriage. Xsi Cloth can be used for this kind of simulation but in the instance described it was a touch slow and had a tendency to become unstable if pushed too far."

I used it once on a character that was dancing with an Ipod, and the headphones cables needed to be realistic animated.
Might help ya, good luck
