continuum mechanical model for cloth simulation
Posted: Wed Feb 05, 2014 4:22 pm
Dear all,
I have just developed a cloth simulation engine. The mechanical model is not particle based but it use continuum mechanics.
It is quite stable (for the same physics based scene I can use the same integration timestep of the default bullet solver), and also fast. I have to extend the mechanical model in order to account for friction and bending force.
IMHO simulation looks quite better than the particle based approach.
I posted on youtube two comparison videos of the two approaches, using bullet as reference for particle based simulation.
You can find the links in the following lines.

Any feedback will be appreciated.
