Hi,

Here's my first test of using Elastolab to output POV spline data. It was
quite a job to construct the environment from polygons and spline data, but
worth the effort I feel.

Any comments welcome.

All the best,

Andy Cocker

nice, how long did you develop this (without rendering)
and what is the strange tick of box at the end of anim?

Oh.  Wow.  I am completely dumbfounded.  Well, almost.

That's great!  I might have to get that.

I can explain the tick of the box.  The box is modeled with particles connected
by rods.  There's a known problem when two particles connected by a rod are in
resting contact with a barrier.  The simulation treats them as two independent
particles and doesn't realize that moving one causes the other to move.  The way
to solve this is to re-formulate the problem and solve a system of linear
equations inside a loop.  This is a lot of work and I'm not certain that it would
run in real-time.  Without that approach, there's a little bit of jitter when two
particles connected by a rod are sitting on a barrier.  I may address that later,
but I felt that it wasn't a big problem for now.

Nice scene -- does it uses radiosity?

Thanks. Yes, it does use radiosity.

Nice.
IIRC Elastolab only does 2d physics. Is that correct? If it does 3d physics, I
have another Q: is it free and where can I get it?

Only 2D I'm afraid. :-(

All the best,
