Re: [osg-users] 3DS loader broken for models that use pivot points?

I, Just an idea but if you want to have a pivot point, add a Helper at the pivot point of your model, and put it as parent of all the model... It is not exactly what you mean, but it can do what you want. Regards, Vincent. 2008/8/6 [EMAIL PROTECTED] I have some 3DS models that I am trying to

[osg-users] Light attenuation do nothing

Hi all, I've a scene with 2 lights : The first one (n°0) is the one for the whole scene, with ambiant component, diffuse, specular, ... The second one is attached on a node, and have to light only this node and not all the scene. To do that, I put some attenuation on the second light to avoid

Hi Vincent, You'll need to set the light number of the light via light-setLightNum(num); The first light should be 0, and your second one 1. Robert. On Wed, Aug 6, 2008 at 10:53 AM, Vincent Bourdier [EMAIL PROTECTED] wrote: Hi all, I've a scene with 2 lights : The first one (n°0) is the

[osg-users] About sort geometry

Hi all, I'm now working on a volume rendering project. What I need is to improve performance. I had to split one volume bounding box into numbers of boxes. The very important work to do is to sort the geometry. Boxes must be rendered from nearest position to farest to get right visual. So,

Hi, Robert, Is there a way to visually see the render order of geometry or the console output of current rendering geometry? The draw callback runs once and I can't use it to determine the render order. Can you give me some advice? Robert Osfield wrote: On Wed, Aug 6, 2008 at 3:09 PM,

Thanks Thibault, I use gDebugger and it should be a way to do so, but it's quite boring to see the OpenGL commands. I must find a way to see the rendering detail in order to debug my program. If there's really no simple way to do this, it will be a pity. Thibault Genessay wrote: Hi, On

[osg-users] OSG 2.6: No OpenGL Context?

In upgrading my app today to OSG 2.6, I couldn't help but noticed that it crashed when I attempted to retrieve the OpenGL Vendor name.  It wasn't a great deal of work to determine that there was no valid OpenGL context when it was called.  A little further work showed that where I called

Re: [osg-users] OSG 2.6: No OpenGL Context?

Hi bbblurururughghghghghhbbb? Sorry no signature on you email so this guess was as good as any. In OSG 2.6 the viewer.frame() by default releases the graphics context rather than keeping it current, this change allows the viewer to be interleaved with other viewers within a single frame loop.

HI Adrian I know for our apps we need to do some investigation of what OGL features we have or don't have , and were doing this in the first draw, which is not ideal as in many cases asking Opengl if it supports feature A is problematic as drivers lie and say they say they support feature A but

Hi Adrian, A good way to add this type of initial setup testing is to use a custom viewer realize operation. The osgshaderterrain example has a such as custom realize operation - although reviewing the code know the actual operation addition is currently commented out with an associated comment
