thanks Ulrich, it worked as expected :) Fred 2010/3/17 Frederic Marmond fmarm...@gmail.com: Thanks Ulrich for the ReadFileCallback, I'll investigate that way :) my need is really to NOT load the textures files for some objects, it's not good for me to only unlink just loaded images. I hope

[osg-users] how to load a model without its textures ?

Hello world, I would like to know if it's possible (and how) to load only geometry data from a 3d model file, without any texture ? I didn't found flags or options for doing so, and the ugly solution that unloads images loaders from the Registry is not an option for me, as I also load full models

[osg-users] question on status of dae (collada) plugin

Hello world, I'm trying to load some collada files from osg, using osgviewer, recent trunk version on msvc8. I tried on those found on the collada-dom package (collada-dom/dom/test/1.4/data/*.dae ), but only one (cube.dae) is really loading. Some crash (segfault), some display an empty scene, and

[osg-users] how to generate shadow map out of renderingTraversals ?

Hi all, I would like to generate a shadow map before the real scene draw, in order to alter it (add 3rd parties objects shadows in it) before applying the shadow map to the 'real' world. The context is that osg is called inside a custom 3D engine, so a post prerender callback won't be enough.

Hi Enke, Blueberry3d is a core library, so it can't be used 'as it'. I don't think there are public demos for it, but you can find screenshots and videos on the bionatics www. Have a look at LandSim3D, an application that uses Blueberry3D for its rendering:
