Hi Ulrich and Todd, I've now reviewed, merged and checked in the changes to src/osgFX/Outline.cpp. I did test the modified osgoutline.cpp and confirmed that problem and that the fix works, but I didn't feel the modifications for the example were appropriate to become the default of this example,

[osg-users] [osgPlugins] error loading an ive file with OSG 2.8.3

Hi, is there any known issue related to the ive plug-in in OSG 2.8.3? I tried to load the same ive with OSG 2.8.2 and it works fine. I can load correctly obj files with 2.8.3 but the ive does not work. Any idea? Regards Gianni -- Read this topic online here:

Hello Gianni, is there any known issue related to the ive plug-in in OSG 2.8.3? I tried to load the same ive with OSG 2.8.2 and it works fine. I can load correctly obj files with 2.8.3 but the ive does not work. Any idea? We have been using 2.8.3 since it came out and have had no problems

[osg-users] Hide/Show Geometry or Primitive Sets

Hi, just a quick question, is it possible to hide and show geometry or primitive sets? In the present case I want to hide/show Linestrips. With a NodeVisitor I can remove them, but I only want to hide and show the LineStrips :) Code: case GL_LINE_STRIP: std::cerr detect a line_strip

Re: [osg-users] Rendering left right stereo frames in separate threads?

Thanks for your help Robert. I think I will take your advice as to seeing why my app is so cpu limited. I am doing a 600 particle simulation using the bullet physics library. Therefore, I have 1 geometry, 600 geodes, 600 materials, and 600 Positionattitudetransforms. The shared geometry and

Re: [osg-users] Hide/Show Geometry or Primitive Sets

HI Mo, The normal way to hide/show elements are to place the elements in separate osg::Geometry attached to separate osg::Geode, then toggle the geode on/off via a NodeMask or by using an osg::Switch as a parent. You could go the route of add/removing primitive sets but this will be more awkward

Re: [osg-users] Rendering left right stereo frames in separate threads?

Hi Brian, I'm I reading your correct - that you have one particle per geometry/geode/material and transforms? If so, well this has got to be the most inefficient scene graph you could possible make. This is a great example of trying to solve a performance problem by looking at completely the

Re: [osg-users] Geometry Drawing Performance

Hi guys, The 700fps is just in wireframe mode with nothing else being drawn. Eventually I'll have to put it in a scene, and apply a special shader effect to it, which could reduce the frame rate. I don't know exactly what the frame rate will be, but I thought it might be fruitful (partially

[osg-users] Keypress broken since rev 11749

It appears that with the changes to GraphicsWindowWin32.cpp at rev 11749 that keypress does not get called when one hits a non special key (eg one of the letter keys). If I understand correctly, non-special keys are no longer totally handled from WM_KEYDOWN and they are supposed to use WM_CHAR or

[osg-users] Why SharedStateManager::share() from main thread?

I've been looking activating the SharedStateManager within the DatabasePager and I was curious to know why the share() function is called from within the main thread (i.e in DatabasePager::addLoadedDataToSceneGraph()) as opposed to the DatabasePager thread (like the GL compile post-process). I
