....could we have a spherical source of gravity?

Aren't we allowed to have at least some fun calling it the SSF?-we know it's reliant entirely upon pragmatism in the physics engine, but that doesn't mean we can't invent silly names for things. :P

....could we have a spherical source of gravity?

I think the only way to mimic that would be to apply at periodic intervals impulses to all objects which pushes them towards a given point, so an object below the point would be pulled upwards, and one orbitting the point would be pushed in different directions over time, towards the centre of the orbit, so that the approximate effect would be that of gravity. If that's the best way to do it, lag would be high.

They're exactly the same - I explained them in that post. The only change is in how it decides what to throw where how fast.

The precise details of what is thrown, and how fast, were what I was experimenting on, and what I haven't looked into for Havok 4 (I already knew that interpenetration caused objects to fly apart, both from you and from my own tests). Sorry for not explaining this better. As for SSF being a product of the simulator's resolution limit, you've explained this before (for which I am thankful)- I just think that SSF is a nicer name.

The direction is random (no time to figure out something better), and the speed is vaguely related to the depth of penetration, but largely also random. Happy? :P

Thread gone off-topic? Would you like a split?

A banana split would go down well, thank you, Alice :P

Well that's useful. :P. Now I just have to try to work out how SL's random number generators work and use that to construct useful laws.

Actually, I think I'll leave it to someone else. :D
