Image Description, by Gabriel RABHI



This small demonstration show a spring based dynamic simulator with a muscle feature. A muscle is a length variable spring. The structure of the animal is only animated by muscle and all behaviors of the structure are generated by simulation of collision particle on the ground.

This is a research demonstration : we are integrating a mesh preservation mechanism and full collision detection. This engine will be used as a full inverse cinematic, skeleton based character and soft and rigid constrained bodies simulator, and should be integrated in our programming tools and in our advanced content creation real-time networked environment now in development.

Reminds me alot of sodaplay, that little internet spring game. Good work :)

now if you added a proper mesh, fur rendering and some ik...

awesome stuff!

The Constructor has always been so fun to play with

I've always thought this kind of thing was the coolest! Combine this with genetic algos and a neural net, and you're talkin' ***AWESOME***!!!

Yes, it's soda play in 3D, with a small modification wich permit a higher stability without multi-conputation for each frame. I'm searching for a algo that permit the preservation of the mesh, taking care of constraints : pivot, axis, rigid, build using springs. So, I have to create a matrix for each indepedent peace of the mesh and changing the velocity to approach the original shape.
In other part, I'm searching to perform collision, with self collision detection and edge to edge collision computation (finding the interection is not so hard, but perform a good animation result is).
By the way, let's said that I have not lot of time to spend in this research, so it go slowly (money should be welcome) ! I'm searching in other technology, that include the efficient EZ GUI library.

Thank's,

Neural nets and genetic are in my mind : my structure will integrate sensors able to inform an "entity" based on logical decision pipeline or neural network to perform a behavior. Muscle will be driven by this logical decision pipeline : INPUT : eye (rays), sound detectore, and in a pipeline builded graphically with our tools (component that you connect), and OUTPUT are the muscle value.

This is in my mind, but I relly need a lot of time to develop this, so... I should start an open source project.

Cool job!

Could you give us the url of your Open source project?

thank you,

I guess you mean inverse Kinematics, not cinematics.. what the hell would inverse cinematics be??? :D

A film that plays backwards? upside down? mirrored? :)

Argh. This is one of the things that I was going to be researching for my dissertation (specifically what Punchey said about neural net/GA control). Specifically for a MMORPG-type environment. Crap, yet ANOTHER project I can't do due to it not being novel anymore. :)

Wow extreme impressive technique!
It would be interesting to see such an muscle system in a game.

I had the same idea... Not for dissertation but as a reasearch project in my spare time. Damn!

Yes, it's an error ! Kinematic, of course !
