Re: [osg-users] Textures problems in FLTK Viewer utility with LOD model and Viewer.
Hi Ulrich. I save the osg format and the Texture2D record is inserted correctly but the file path disappears (I load objects that already have the textures, I don't apply the textures in my tool). I'm going to try to use setUnRefImageDataAfterApply before using setSceneData. I'll tell you if it works, meanwhile thanks :D Best regards Dario Ulrich Hertlein wrote: Are you saving '.ive' files with inlined textures by any chance?

You can prevent this by calling 'setUnRefImageDataAfterApply(false)' on the textures. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=31031#31031 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi, Hi Ulrich. Yes, I've made a Visitor to setUnRefImageDataAfterApply(false) for all textures properties and now works like charm. Thank you!

Hello Dario, Yes, I've made a Visitor to setUnRefImageDataAfterApply(false) for all textures properties and now works like charm. If you want to have less code to maintain, you could just use the osgUtil::Optimizer::TextureVisitor like this: osgUtil::Optimizer::TextureVisitor visitor(true, false, false, false, false, 0.0); (check the names of the arguments in the header to see what they mean... But it works well, we've used it before) J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

My bad - it's not only the image data that's released/unref'd but the entire osg::Image, so the file name is no longer available as well. Good to hear it's working for you.

[osg-users] Textures problems in FLTK Viewer utility with LOD model and Viewer.
Hi, I have a very strange problem. I've written an FLTK application, which use the viewer (pretty similar to the FLTKViewer in the OSG examples), that compose and show LOD models. I can load multiples models and I inserted these models as childs of an osg::LOD node. Then, I've tried to write the LOD model into a file using writeObject method and ref_ptr original LOD pointer as first parameter. Now, I've a strange behaviour. In the viewer ALL WORKS FINE, I can see the models switch and all relatives textures correctly. The written LOD model is correct in terms of meshes (I see the correct models transition when the bound is reached) but there is a very strange problem with the textures (assuming to use 2 models): 1. If I DON'T switch between near and middle object in the viewer, then the LOD model written have NO TEXTURE for the NEAR object, but have the CORRECT texture for the second model! 2. If I SWITCH between near and middle object in the viewer, then I see NO TEXTURE for all LOD objects models. I've tried to disable the my_viewer-setSceneData(LOD_model_pointer) (and the Fl::redraw() idle action), so that I can't view the models loaded in the viewer. In this case, the LOD written model is correct!!! There are all textures!!! I've tried also writing the LOD model without using the graphical application (this is rougly the same test...) and, obviously, all works fine!!! So, seems that if an object is visualized under the viewer, then the writeObject method don't writes the textures informations, otherwise is ok. In effects, the near model is ever showed as first and so don't ever has the textures. The viewer locks the texture informations...?!? This is very strange for me... Can you help me? Many thanks!
