Hello,
I've been working on an engine that combines sdl, osg, bullet, open al, and
now lua for roughly 6 weeks. Static and dynamic entity creation works well
on the fly if handled with C++ code, however if I attempt to off-load this
logic to lua, I run into problems. Below is an example of code
Sure, no problem at all.
However, I'm now doing further investigation for simpler code to do
the same thing. I'm wondering if version check is actually needed for
each extension availability check. Since OpenGL must be upward
compatible, you can call only isGLExtensionEnabled for that purpose.
The

Thank you Robert for this nice tool. Before I report my results, my

1) Perform all the standard tests, and format the output for easy posting:

Hi Robert,
I've looked into this a little further. It appears the changes you made
to ParticleSystem.cpp on March 17th is the reason for the behavior
change. I don't have a solution yet other than backing out the changes.
I'm still trying to understand what you're doing in the

It sounds like a palette override flag issue.
If the ProxyNode comes from importing a FLT file, it will have a ParentPools
object attached to indicate how the override flags should be set during

You can share whole subgraphs as well as individual components. I'd
recommend sharing StateSet/StateAttributes as much as possible to help

I am working on porting my raw/native/whatever-you-want-to-call-it

objects of the same type, I reuse the VBO created for the original
object. Is this something I can do in OSG?

Hi, I wish I had some friends at NVidia. But unfortunately they not seem to
