Hello dear OSG-community, OSG 3.4.0 Windows binaries built with Visual C++ 2015 and Intel C++ 2016 are now available from this page on my company's site: http://objexx.com/OpenSceneGraph.html
A ReadMe.txt file in the root directory of the expanded package has some details. These are 64-bit builds with the default GL2 OpenGL level and these dependencies: curl, freetype, giflib, glut, jpeg, lpng, minizip, tiff, zlib. We can add other plugins (GDAL, Collada, ...) based on community interest. There is a vanilla VC++ build and also builds optimized for AVX2 (Haswell and later) CPUs. We are going to do some performance comparisons to see if the AVX2 and/or Intel C++ are beneficial for our application: we also welcome feedback on performance from the community. The Intel C++ build should be binary compatible with VC++ 2015 so you don't need Intel C++ to use it. Note that it was built with /fp:fast=2 to enable auto-vectorization of floating point loops: this could cause small precision loss that might matter with larger/geo distance scales. If vectorization isn't significant/beneficial this option may be dropped: input on this is welcomed. We hope to do some OSG profiling and experiment with tuning on the Windows side with VTune: if we find anything interesting we'll post it on our OSG page and submit code back to the developers. We don't have a need for 32-bit builds or older compilers but feel free to ask ;) . Since we need these ourselves we plan to post binaries for future OSG and compiler releases as a way to give back to the OSG community.
