Here's new iRIGID tech demo... it's the updated version of my rigid body dynamics engine.

New features:
- Supports complex static objects (with point to line collision for very accurate collision detection)
- Includes iBULLET engine for creation of thousands of small rigid body bullets... they act as correct as bigger rigid bodies.
- New improved friction modelling.
- New improved collision handling.

Download and have fun...
And tell me how it runs.

I am speechless!
This is actually f***ing awsome!

Absolutely awesome! This system has really come a long way. Even with 200 objects and bullets on I was getting 52 fps on a P4 1.6 / Geforce2 MX400 / 800x600x32. Really demonstrates what Blitz (and Bouncer) is capable of.

100 objects with bullets - 82 fps
100 objects no bullets - 118 fps

Great job,
MK

Is it done in 2D or 3D? I saw you used some alphablending in there..


Bouncer(Posted 2003) [#5]
It's using 3D... but the engine is for 2D use.

/me gets up off the floor

You're just itching for that oscar award but you'll have to make do with this old one :-<


with 200 objects and 4.0 iterations
-------------------------------------
800x600 = 51FPS
1024x768 = 46FPS


In a word .. "breathtaking"

lol... ;)
It's going to get there.... just wait.

WOW! :)

Christ! So impressive :)

WOOAAAAAOOOW, keepup the good work


starfox(Posted 2003) [#11]
why 32 bit? can you please put 16?

Looks awesome!
After a view minutes watching it (couldnt help but stare) i got a Memory Access Violation :/


Bouncer(Posted 2003) [#13]
Ravey: does it happen every time you run the demo?

starfox: Sorry. 16 bit mode is not currently supportet due some bullet collision detection related issues... 16 bit modes will be back when I get the problem sorted.

Check out the new stress test.... with 400 objects.
Did some more collision optimizations. Now the bottleneck really is just the amount of surfaces in 3D objects.



would like some feedback on how it runs...

and btw. it's 16bit 800*600 so everybody should be able to test.

With 400/400 objects on screen (grav on), I get about 67 (fps limit off) and 51 with frame limit on.

I can get upto 400 fps with all 400 objects off screen (grav off let all objects float up)

The bullet thing doesnt seem to work.

All of the objects load and draw fast. Good stuff

Yes... I disabled the bullet thing for this stress test... just wanted to see how the engine runs with my new collision system.
