Hi, A first try for a new build system including OSG for MSVC8 is at http://www.oflebbe.de/oflebbe/FlightGear. I was able to compile and run sucessfully a FlightGear executable from it. Greetings Olaf |

Hi Olaf, I have used your project files / precompiled libs to compile fg with osg from the scratch. It worked with only negligible problems. A file simgear_config.h is missing; there is a simgear_config.h.vc5, after renaiming to *.h it works. 2 files had to be added to the simgear project file: SGStateAttributeVisitor.cxx and SGTextureStateAttributeVisitor.cxx and 1 file has to be removed from the flightgerlib project file: rotorblade.cpp to get compatible with actual cvs. A very big thank you to Olaf Flebbe, with your package it's very easy to compile fg from the scratch with mcsvc express. But there is one problem with the running flightgear than: it's about a factor 2 slower than the flightgear with plib (and shadows on)! I don't know if this can be improved with other compiler flags, but I am a little bit surprised. And I fear, that with shadows the frame rate will be decreased further. I am using a P4 2.2Ghz with GeForce Fx 5600Go @Olaf: what is your experience regarding the frame rate with osg vs. plib?

A GeForce FX 5200Go and an ATI X1600Pro both show a significant slowdown. I have to doublecheck compiler settings.... The Slowdown on the ATI Thingy is definetly not CPU bound... Olaf |
