Hi Patrick,
Playing movies automatically isn't that what all users will want all
the time, so hard coding this in isn't appropriate. In the past I've
always just used a custom NodeVisitor to traverse through an enable
the movies, this is pretty straight forward to write and retains

I'm afraid you don't really say enough about the specifics of your

With your View, do they are share the same GaphicsWindow? How do you

graph, how do you grab the live

These methods are virtual methods, and ImageStream is a base class...

Hi all,
I would like to add shading effects to my application, which uses OSG, but
have never programmed GLSL or Cg before. Can anyone please guide me to
tutorials or a good source of information about using GLSL with OSG?
I noticed that OSG comes with one or two shading examples but I would

I have been studying GLSL in OSG like you :) I have made lots of search and

Hi Fabian,
The first problem to resolve is the fact that views are each using a
separate GraphicsWindow, this means a separate GraphicsContext for
each view, which in term means that FBO's/texture objects/display

of contexts,

Hi Adrian,
It's nice to hear that performance is looking good, but... as to what
changed all depends upon the delta between the last time your tested
and when you just did your svn update.

Call Stack:

If TextureInit is, for example, a singleton that persists for the life of
the application, then it's destructor never gets called. However, it only
allocates once. If this is the case, then technically speaking it's not a
leak, at least not the kind of leak that would impact anyone's application.
