Position-based Elastic Rods [Basic Demo]

Post by Remotion »

Hello,

since some one already tried to implement this, here are my first experiment.

Time step is set to 1/60 (one step per frame) and solver iteration to 32, for now this can not be changed.
There is no self collision detection only simple collision with the ground.
I just wanted to make the main constraints work first.

So the very basic demo is attached that show only one elastic road.
May be later I will update it to something more interesting...

Great work! More control over the rod would be nice (dragging by mouse etc.). What is you computation time per 1 iteration?

Thanks,

This was only fast and dirty prototype.
So I have no plans to extend this demo.

It was pretty fast, of course it is dependent on number of points.

I cant run your demo. It ways cannot find libiomp5md.lib

I can certainly help with this if you need it.

Hi mobeen,

You probably need "Redistributable libraries of Intel(® C++ Compiler for Windows Update 2"

I saw you other work here and it is very interesting.
By the way I was using GLM for this prototype too.
May be a later if I have some time I could cleanup the code and make it open-source, but not now.

regards,
Remo
