Re: [osg-users] [osgPlugins] DDS Texture vanish with LINEAR_MIPMAP_LINEAR

Hi, I just tried the compilation of my test code on Microsoft Visual C++, and the problem does not appear so it seems gcc linked... I will try to recompile OSG on my different platforms using cmath in osg/Math, hoping we don't see any other bugs. Will keep you informed later today.

Re: [osg-users] [osgPlugins] DDS Texture vanish with LINEAR_MIPMAP_LINEAR

Robert, I just tried another solution, which works and is maybe, let's say, more correct from a coding point of view. Indeed, we want to floor a division of two floats, so we should logically use floorf instead of floor, because in math.h floor is only double. That's also the reason we don't

Hi Robert, yes I also tried on this little code to make an osgconv, that's the way I used to find that the problem comes from the PrimitiveSets. The file generated by osgconv merges the two primitiveSets in only one, ie : Before :

[osg-users] about the OSG SVG plugin

Hi all, I'm trying to use the OSG SVG plugin to read some .svg file, to be used as textures on some surfaces. Since .svg is a 'vector' graphic format, it could be rasterized at any resolution. So, I should be able to ask any desired size for the image read by the plugin. I'm using following

Re: [osg-users] seg fault with text-setText(mystring) called in NodeCallback

Hi David, Best guess would be that you are running the viewer multi-threaded (it's default if you have a multicore processor) and the update traversal to the text is occurring at the same time as the draw traversal that is reading. The solution is to tell the scene graph that you plan to
