Bullet JavaScript API

Hi all, I am very happy that Bullet have set its foot inside the browser via the NativeClient. There are already a few examples on how to use it that way. However, it makes me sad that it cannot be used together with WebGL. For that, a fast JavaScript API is needed. Of course, there is ammo.js (the ...

Re: Box on an inclined plane... friction?

Thanks! That did it. I set the friction to sqrt(0.35) instead, hence the contact friction will become sqrt(0.35)*sqrt(0.35)=0.35. The angle in which the box starts to slide is now 18.1 degrees. Not perfect but still close to the analytical solution 19.3. Do you have any hints for parameter tweaks to...

Box on an inclined plane... friction?

Hi everyone! I'm doing some tests with several physics simulation tools and I've found something interesting when it comes to friction in Bullet. I have a box on an plane. The plane is inclined by an angle phi. The friction parameter "mu" is set to 0.35 on both of them. Analytically, one can show th...

SAP or Dynamic tree when simulating LOTS of spheres?

Hi everyone. Earlier today I tried to run a simulation with lots of particles. They are at start lined up in a cubic structure with little or no space in between. They are supposed to fall down into a container made out of static boxes and I'm going to analyse the force network in the system. The th...
