Re: [osg-users] SDL and OSG in the same project

Re: [osg-users] SDL and OSG in the same project

Maybe msvcrt.dll in the list there has nothing to do with the problem. I clicked around in dependency walker some more (still learning) and found that sdl.dll uses msvcr90.dll which is obviously not for debug. That has to the problem. But still, I compiled SDL correctly the first time, and

[osg-users] Texture object preparation...

Hi All, Is there a way I can get a Texture to perform its preparation at construction time, rather than when it is first required for rendering? Essentially I'm noticing a significant lag on the first frame that requires a Texture to be rendered. I've tracked it down to the Texture::apply()

[osg-users] Crash in Viewer Destructor

Hi all, I have a crash on a composite viewer destructor, and I do not see anything strange or wrong in my code. My viewer is managed as an external lib, and the frame() call are done by a method, like the close() call to finish a viewer. So, if I use the viewer-run() there is no problem, but

Re: [osg-users] Texture object preparation...

Hi Neil, The osgViewer by default will compile texture and display lists on the first frame of rendering, but if you add textures later these won't be pre-compiled. You can only compile texture objects from within a valid graphics context, so you can't just do it a construction time. The only

Hi Vincent, What exactly do you mean by when I use the other way and call the destructor (I clear the viewer map I get) there is a crash in, as these seems odd, you never call the destructor, all you can do is call delete, but in the case of the Viewer class you should never be calling delete

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.

Hi Sukeder, Thanks Sukender. I have decided to achieve Collision Detection in Physics Engine as you suggested. And I have searched about PhysX library and I found lots of paper which says we can only use PhsyX if we have geforce * or upper level graphics card. And so I don't think about using it.

Re: [osg-users] Geometry drawable color after Triangulation

Hi ulrich, Thank you very much, now I can see it just fine! Another question, though, because I am new to osg, and probabily this is the next step I want to do the previous code: does osg have any functions for smoothing a surface? or should I implement it manually? Cheers, Nadia

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.

Hi Ümit, Isn't the geforce* needed only when you want to accelerate PhysX (=computed partially on the GPU)? Anyway, if you wish an engine and don't know which one to choose, you can always try PAL (Physics Abstraction Layer), which works with ODE, Bullet, PhysX, and more (

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.

I can say that I am 100% sure that you do not need a Geforce card, or actually any video card at all, to write and use programs that are built on the PhysX SDK. You would only need a Geforce card if you decided to use hardware acceleration, which currently only works for fluids and cloths. So

Re: [osg-users] Crash in Viewer Destructor

Hi Robert, The 3d engine is called by an other application, frame by frame, so the application call a personal method to close a View (we have one or more Viewer). There is a map to get the viewer pointer associated to the Opengl Context it has, which allow us modifying a viewer or an other one.

Hi Vin, That's a pretty big field, but I would suggest looking into SPH (Smooth Particle Hydrodynamics). It's a fast, gridless, particle implementation. Otherwise, there is no easy way to do liquids, generally. SPH is probably the easiest. (IMHO, of course). Good luck! Charles On Thu, Jun
