Hi:

   Here is a more serious scene done with the Bullet Physics Playground,
to test "real world" usage.

   Some of the fruits (pear, banana) and the cloth come from the
3Drender.com "Lighting Challenge" scene by Dan Wade. The rest was my own
models, and a fruit bowl I modelled with Wings3D.

   The cloth and the bowl where made static on the simulation, while the
fruits arranged over it are dynamic, so they fall to fill the bowl
(actually I put a lot more than needed, to have some of them lying
around on the cloth).

   I attached two screenshots from the playground, one at step 0, and the
other at mid way to the final one (I stopped it when all the "excess"
fruits did fall over the cloth borders, at step 394).

   Regards,

--

Hey cool ... nice test of mixed objects. Did you have same problem I had 
with the inner surface of the bowl? Now that I think about it maybe it 
was because I used a sphere then deleted all the faces above the equator 
for the basic shape ... or maybe a blender-ism with how the shape was 
initially created. Flipping normals (on inside of bowl) did the trick. 
Thanks for posting ... it gives me something to aspire to ;-) Oh yeah 
... and especially thanks for the work on the application as well .. 
it's been a bit since I've had this much interest in /anything/

   I had the bananas going through the bowl surface at first try, but it
was because I used a non-smoothed mesh, with too big faces (bigger than
the banana radius).

   I never had any normals problem with Wings3D, with objects made by me
(but had to use the "invert" feature a few times with 3rd party 3ds
files). Surely inverted normals do not help on the simulation... :)

   Me too... this has me really hooked. And it's only the very beginning!

Nice still life, but the apple-mesh doesn't look very healthy and the 
same goes for the banana-texture. Cloth and bowl are gorgeous.

Extremely impressive!

Only problem with regard to real life fruit bowls may be that the
latter are usually not filled using the random drop technique and thus
exhibit a higher degree of orderedness ;)

Dropping fruit in general is not recommended ;-)

The apples look strange to me (mesh problem at the end?) but otherwise 
it is a beautiful scene.

The apple looks rather like a classical isosurface, but badly tuned on
that picture.

   Thanks... and yes, the apple is badly done. In fact, it isn't an apple
at all, but a tomato from my kitchen scene which was quickly re-shaped
into an apple (without much success).

   The banana texture is difficult to achieve without SSLT....

   Yes, but that was the easy way... :)

   No, Thomas was right: it's a mesh and it has a problem on the ends. I
should really make a better one starting from he scratch.

   Thanks: I didn't remember that one. Now, if I could get a mesh with
the same shape for the simulation... :)
