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

robertosfield, thanks for stopping by and weighing in. I agree, the scene graph itself is likely the performance bottleneck. We're going to do some additional profiling in the coming weeks. I have lots of ideas. Thank you to all others as well. That "Just Say No to Scene Graphs" article is

Not that I know of, but Nick can probably report on if there is a roadmap that includes that. On Fri, Apr 22, 2016 at 9:50 AM, Shayne Tueller wrote: > This is probably off topic but since OpenIG was brought up, I had a > question about it... > > Does OpenIG support

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

This is probably off topic but since OpenIG was brought up, I had a question about it... Does OpenIG support CIGI? If it doesn't, adding it would go a long way in making it more mainstream in the IG community. It would sure make it easier for a host that is using CIGI to switch over... Shayne

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

I've made a few games in OSG and in Unity. In my experience OSG blows Unity out of the water then it comes to render performance. Also with unity and game engines in general you have to learn a lot of quirks. Like learning that in unity turning objects on and off is actually really expensive

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

I found the article I was referring to. It has disappeared from its original source, but thankfully the Internet Archive has preserved a copy. It made considerable waves in game engine programming back in 2006: Tom Forsyth's "Scene Graphs Just Say No"

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

There’s a couple of major reasons OSG isn’t used in games much. Probably the most important one is that it isn’t a complete game engine. Unreal, Cryengine, Unity (and also the likes of Gamemaker and Marmalade) all have favourable licensing conditions, and they can be used to start knocking

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

Personally I don't feel it's games are critical to the success of scene graph like the OpenSceneGraph. Short lived game titles have very different focus that graphics application that have a long shelf life. A game will be developed then have year of big sales, then perhaps might be followed up

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

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

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

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
