Raydium 3D Game Engine

Since a few weeks now, Raydium provides a support for GLSL (OpenGL Shading Language), allowing Toon style rendering, Normal Maps, Water effect and so on. The doc is not ready yet, but a demo application is available in current sources and SDK, and a water demo will come (very) soon.





A video is available for water effect :

Also, new effects are about to be added to the engine, including environment maps (reflections) and ... HDR post processing !







More to come !

Great

extra

Bravo, super boulot (comme d'habitude ^^)

En voyant la video avec l'eau, je me suis demandé si Ode gère ce genre de truc ? par exemple, si on lance la clio de ManiaDrive dans l'eau, il se passe quoi ? ^^

Encore bravo

Pour ODE, la réponse est simple : rien ! Il s'agit d'un effet visuel uniquement

the thread was in english

Well, yes, you're right
Totoro was wondering how ODE was dealing with this water. What will happend if we launch the ManiaDrive's car in the water ?

The answer was "nothing", since this water effect is only a "visual" effect. To be cleanr, ODE only simulates physics for rigid bodies, not fluids. The keyword for future Raydium enhancements about this subject is "buoyancy".

hmm, interesting.
Is posible in raydium to define areas with diferent universal values?
If it's posible, we could emulate a high-density fluid by setting the gravity to -4 instead of 9.8(for example). In that way, if the car get into that arear it will null the inercial gravity force and the object will eventually go surface.

Buoyancy is way more complex than this. For example, deeper an "floating" object is, harder it will be pushed to the water surface. The shape of the object is important, too (think about a thin wood lumber) and will act on rotation. All this can't be simulated only with a negative gravity.

There were some very interesting threads on ODE mailing list about this subject, I'll take a look one day We must have "water blow" particles effect, too.

Sorry for my no-english post (but i'm too bad in english ^^)

Buoyancy is an "addon" to Ode, or it's replace Ode?

"water blow" c'est des vagues?

We'll not replace ODE, but we'll try to enhance ODE to support buoyancy for bodies. You're right, it's sort of an "add-on"


Oui. Dans le détail, je pensais plus à des "gerbes d'eau".
