with the release before UT 2K3
It was crap then and I doubt it's got any better. The last UT sucked
nads. And actually so did the one
before that.
It was pretty much on a par with Valve's 'Hammer Editor' which is also
a massive
is it OK to create a viewer in e.g. the main thread and then call frame()
from a different thread? We're getting erratic results on Linux vs
Windows
vs Mac. So I just want to know if this use case is legal.
I've done this under Linux - the osgqtbrowser example in svn/trunk has
the option

Anyone else have reports on osgqtbrowser on Windows?
thanks

Windozes is same as Mac, only the owner thread can retrieve events for
windows.
can
Hi Jason,
The good old days... :)
Thank you so much for taking the time to spell it out for me. It is very
helpful. Now at least I have somewhere to start.
Take care now and have a great weekend.

interfaces to Performer. The software package we want to port uses the c
interface, as one of the required external module is in C. I am assuming this
will not be an issue?
Thank you much

Try glFinish after frame()

Hi,
I save it in a file. The problem is with frame(). If I call viewer.run() and
hit Esc to quit the viewer the image is complete.
Thank you!
Cheers,

Calculating the perfect bounding sphere is an expensive operation.
You need to calc the convex hull which is O(n log n).
osg uses a fast approximation which is generally good enough.

Hi All,
I’m having problem computing the global bounding
Anybody know of a osg compatible material editor/designer?
Repeating the edit/compile/link/curse cycle is starting to get a little tedious.
I'm sure I saw a post about one not so long ago, but I'm damned if I
can find it now.
tia.

The clipping you are seeing is probably due to osg's computation of
the near and far clipping planes.
You'll need to implement computeBound so osg knows about your object.
Have a look in ShapeDrawable.cpp
