Re: [osg-users] GLU integration
Hi Stephan, I checked fixes for these errors yesterday evening - there were warnings for me with g++ 4.3.3. Could you do an svn update and let me know if this fixes things. Cheers, Robert.

Re: [osg-users] GLU integration
Hi All, I have now moved the subset of glu functions that are now part of the core OSG library into the osg namespace, so the likes of gluScaleImage now would be used osg::gluScaleImage. I have also introduced a gluScaleImage version that doesn't use glGet's, instead you pass in a PixelStorageModes object that provides all the appropriate settings. This version of gluScaleImage is particularly useful as it allows the function to be used anywhere in your application - you aren't limited just calling it from a thread with a valid graphics context. The osg::Image::scaleImage() and osg::Image::copySubImage() methods now use this new gluScaleImage function which means that both these methods can be now called anywhere in your app, at any stage, so you can move scaling and changing pixel formats into plugins, or into pre-processing functions in your application. The osgphotoalbum and osgtexture3D examples both had to use a local graphics context to do rescaling work then needed to do, and now thanks to new flexibility they no longer need this temporary graphics context, so the code is now simplified - one just directly calls the scale image functions without restriction.

Looks like Windows, Linux and OSX now build fine. My guess is that other unix platforms will be fine too. Next step will be to test build out on GLES targets, this may introduce new problems as the GLU code base won't ever have been used when building against GLES.

[osg-users] GLU integration
Hi All, Yesterday I did a review of Mesa's/sgi GLU implementation to look at the practicality of merging several GLU implementation directly into the core OSG. The motivations behind are to make it possible to build the OSG with the GLU features across all GL targets - including GLES, and GL 3/4 where GLU is not supported, and also enable us to tweak the GLU implementations so that we can call them from threads that don't have a valid graphics context current. It also simplifies the dependency chain a little as we will no longer require the external GLU library. My review and preliminary experiments with integration went well so today I bit the bullet and dived in at doing the code integration. I now have the OSG building under Linux without the external GLU library. The include/osg/GLU header now contains a subset of the glu.h, with small tweaks to make things compile within the OSG, and have placed the implementations in src/osg/glu/libutil and glu/libtess which mirrors the structure found in Mesa so further down the line we should be able to keep track of changes more easily. I have already checked my changes in, and have done fresh check-out's under Linux and everything so far has built. I have feedback from Jean-Sebastien Guay that things aren't yet compiling under Windows, and I've applied some of his fixes as well as a few more of my own to try and get things compiling. I'm expecting this process to require a few iterations behind we have a clean build on Windows and Linux. I would appreciate testing under other platforms as well. My hope is that we'll be able to quickly settle the code down and have it compiling without issue across all platforms. The more users who pitch in with testing of svn/trunk the quicker we should be able to find all the issues and resolve them. I'll be watching the list like a hawk for problems and will try and get fixes in a soon as possible. I do have to sleep later so it'd be great if we could resolve all the major problems in the next hour or so, otherwise we might just have broken build overnight. Thanks in advance with you assistance on testing, Robert.
