generateBendingConstraints with softbodies

[jonathangagnon]

Hi,
I have to managed soft bodies with 10 000 polygons.
The problem is that the method generateBendingConstraints computation time is exponential with the number of polygons.
Therefore, for a 10 000 polygons, it takes 10 minutes.
Is there a way to optimise this process ?
Thanks

Yes, we should use a spatial hierachy, such as the btDbvt tree to accelerate this process.

Let's create an issue for this.

Thanks,

So did anything ever get put in for this? I'm guessing not, as my Shiva Bullet plugin is taking 200ms to create the bending constraints for a 600 vertex model. Is there any other options to improve performance? I've seen a couple posts talking about pose matching, but that's not the best solution my for use cases, and bending constraints works quite well, despite the setup time.
