Re: Simulation Islands: Corner-case issues

Yes, I also think checking the differences would be too costly. I asked the question originally to confirm if this was the reason. Manually activating the objects seems to be the only solution in this case. Anyway, in the end I ended up implementing the same scheme in my engine. Maybe in the future ...

raw-physics, a simple rigid body physics engine created with XPBD

raw-physics is a project that I have been working during the past few months. https://github.com/felipeek/raw-physics It is a rigid body physics simulator powered by XPBD for collision response and GJK+EPA for collision detection. Specifically: Collision Response: All of the collision response is ha...

Re: XPBD rigid-body simulation with hard penetration constraints

hey jhelsing,

what a coincidence, I also recently implemented this paper! This is the state of my engine atm: https://github.com/felipeek/raw-physics

if you are interested, send me a message and we can probably help each other with these problems. I'm currently implementing joints.

Simulation Islands: Corner-case issues

Hello everyone! Last days I've been taking a look at how Bullet implement simulation islands, since I am implementing a similar scheme in my engine. I saw that bullet runs a broad phase with AABBs and then collect the islands based on it (the AABBs are increased a bit to account for 'contact thresho...
