Particle System... again...

Hi All,

Farshizzo posted an example of particle by using .osg format in this thread...

Does anyone know how to create an OSG for creating particles? is there a specific editor for it?

Can't we do it inside Vizard?

The .osg file is an Open Scene Graph description. It's just text, like a python script or an html web page, so if you drag it onto a Notepad or into the Vizard editor, you can see its contents and make changes.

As farshizzo explained, there's no particle modeling interface in the current version of Vizard. In my opinion, Vizard seems to focus more on the scripting side to make your sims than on the modeling side. There are dedicated modeler applications on the market that can produce OSG files, which would should well with the Vizard workflow.

Once you see the contents of the dust.osg file he provided, you'll see that it's about a page and a half of parameters. These describe the appearance, the lifetime and the generational behavior of each particle, as well as the direction and rate at which the emitter should create new particles.

I did find a few technical references on the Open Scene Graph system, starting with, though from this I'm glad that Vizard hides much of the complexity for other scene objects.

Smile I see

Thanks for the info. For now, I'll just play around with the setting in .OSG file. Hopefully there will be an interface to do this.

Thanks for your time replying my post!.
