Re: [osg-users] [osgPlugins] DDS textures not loading on Mac OSX and the latest trunk(3.5.0)

Hi, I had modified the code to just ignore all loaded mipmaps in a few of the plugins to fix it, but everything work in older versions of OSG. The code is so different now, it's hard to tell what change triggered the problem. David -- Read this topic online here:

Re: [osg-users] OS X (10.9) Texture2D with hardware compression results in no texture data.

I did do a diff between 3.2.1 in Texture and Texture2D, but there are so many changes it got muddy. I have a lot to do before next week, so unless someone else finds it before then, I'll just have to stick with what I have until then. Thank you all for the quick replies. David

[osg-users] OS X (10.9) Texture2D with hardware compression results in no texture data.

Hello everyone, I started upgrading delta3d to use osg 3.3.x, but I ran into a strange problem that that seems like it must be something that changed in the osg::Texture code, thought it only manifests on OS X. The texture is setting compressed mode, I think it turns on mip mapping correctly,

Re: [osg-users] Qt and OSG

Try the Qt demo where you can set all the window flags. I've tried in on Windows XP, Linux, and Mac OS X, and many of the flags don't really do much, and it's system dependent. I was unable to find a set of flags that would create a borderless window either. -- Read this

We never create particle systems in code. Artists create them in the delta3d particle system editor. You can see all of your changes and tweaks in realtime and then save an osg file. I don't see creating a particle system as a programming task at all. It's an art asset. I don't see why you

It seems to be both that and the osg file. Someone developed a hack that caches the osg file in memory and just reparses it. That helps, but the texture load hits it too. -- Read this topic online here: http://osgforum.tevs.eu/viewtopic.php?p=4609#4609

Re: [osg-users] Long-standing Particle System File loading IO performance trouble

It's being done in the main loop, but we would actually prefer to load assets up front and cache them. Loading resources in a background thread queue is something I would like to do, but either way, that still has latency, plus there is no reason to have to load a particle system more than

Re: [osg-users] [osgPhysics] Project osgPhysics started!

I guess I understand why people do it, but I would rather that OSG kept the limited scope of being a scene graph, that is with the features just of doing 3d rendering. I think a more limited scope makes it more useful as a drop in component of a game engine. physics and audio, while they

This has been discussed on this list a number of times in the past, but I never saw any resolution. osgParticle systems cannot be cloned, so they can't be cached and cloned any time you want to use one. This means that each time a particle system is needed, it must either be read from disk
