Re: [osg-users] Open Scene Graph 3.4.0 has bug when using two monitor setup

Hi Bruce Clay According my experience,you can try to upgrade your display driver to the newest version,mostly the problem will disappear. zhuwan 12,20,2016 > -原始邮件- > 发件人: "Bruce Clay" > 发送时间: 2016-12-20 5:34:08 > 收件人: osg-users@lists.openscenegraph.org > 抄送: >

Re: [osg-users] Open Scene Graph 3.4.0 has bug when using two monitor setup

Robert: Just to be sure I pulled the latest git release and diffed it against the code I had and only found differences in commented headers. I built the code as I had previously and got the same errors. I am using the 32 bit version of 3rd party dependencies which is not the latest posted

Re: [osg-users] About Boat Movement

Have an article about the topic in the context of game programming. The water surface is modeled as a mesh. http://www.gamasutra.com/view/news/237528/Water_interaction_model_for_boats_in_video_games.php As you see, it's complicated subject matter even at the level of abstraction provided here.

Re: [osg-users] About Boat Movement

To do it correctly, you need physics simulation (mass of ship, buoyancy forces as a function of immersion depth at different hull sections, water forces due to flow currents and kinetic energy of the waves hitting the ship) You could simplify this problem into a mass-spring system with lots of

Re: [osg-users] Open Scene Graph 3.4.0 has bug when using two monitor setup

Hi Bruce, I am surprised that this is an issue, the OSG has long been able to run multi-threaded across multiple monitors, it's a fundamental part of the OSG design. I don't personally use Windows too often so there might be a Windows specific issue that others under Windows didn't pick up on
