[osg-users] getFrameBufferObject from a child camera

I've added a camera as a child to the main view camera. This camera renders to a texture using a FBO. I'm trying to get the FBO of this child camera so I can redirect it to different textures during runtime. I'm attempting to get the FBO using this technique but its not working when the camera

Re: [osg-users] Why isn't OpenSceneGraph used in games?

AAA Games tend to not use OpenGL much these days. At one pointOpenGL development wasn't able to catch up to DirectX feature wise (simply too much buerocracy in the decision making pipeline) - that's when OpenGL lost developers to DirectX. Also OpenGL driver quality on Windows was often way behind

Re: [osg-users] Why isn't OpenSceneGraph used in games?

Hi, Good point, but I think there's more to it than just performance. There are games using off-the-shelf scene graphs, for example Bethesda RPG games (Elder Scrolls, Fallout) are built on Gamebryo, which is a general purpose scene graph much like the OSG. (Note Gamebryo is a bit more than just

Re: [osg-users] Why isn't OpenSceneGraph used in games?

Hi Michael, After building 1.5 games using OSG, I'm surprised there aren't more. OSG is probably built to be general-purpose first and high-performance second. So this might scare away someone building an extremely high-fidelity game. But for anything less OSG is fine. Also, being free and having a

Re: [osg-users] Why isn't OpenSceneGraph used in games?

I will jump in with an add as well (please don't be mad at me, it is still about OSG :-) ) Have a look at http://openig.compro.net It is a very thin and simple Image Generator on top of OSG, opensource as well, and it does have some features implemented that are common in the game dev ( I am not

Re: [osg-users] Why isn't OpenSceneGraph used in games?

AAA Games tend to not use ANY off the shelf engine technology, because they like to be able to hack up and optimize everything down to the lowest level. A scene graph such as OSG (or any other scene graph, really) tends to be setup to work well for a large number of general cases, which means it m

Re: [osg-users] Why isn't OpenSceneGraph used in games?

Can anyone explain to me why OpenSceneGraph isn't used in the games industry? There seems to be a large stigma surrounding OSG's performance, but is there really a problem here or not? OSG's own website claims "high performance". Is it really? I've heard reports that people have had to keep the

[osg-users] Custom GraphicsContext Segmentation Fault when using Multithreading

DISCLAIMER: I'm not a graphics or OpenGL expert, so if something is dumb or doesnt make sense please let me know. Hi, I am trying to use OSG to create an application for a real time Linux system without a windowing system. To get OSG to work properly, I create my own GraphicsContext and assign

[osg-users] Heresy: Direct3D?

I know it's persona non grata, but this is the best community of performance 3D GPU people I know, so I'll ask. I might need a subcontractor who is skilled in both OpenGL and modern Direct3D in the future. If you're in the US and are interesting in doing work like that, contact me privately of

Re: [osg-users] Windows7/VS2013/CMake error

Hi Robert, In some occasions this can be solved by putting the cmake-installation path and the visual studio "VC\bin" into the PATH environment (Rapid Environment Editor [1] is a great tool to do this without any pain). If this doesn't help, start cmake-gui from the visual studio console. Hope

HI All. I am just setting a Windows 7 build machine, having installed VS2013 and CMake 3.5.2. On attempting to build the OSG (from github master), I get the follow error report from CMakeSetup. I've got VS2013 on another Wiindows 7 machine and haven't seen this error. I've reinstalled both VS20
