I generate a texture as follows:
osg::Texture2D * map ()
{
int width = 38, height = 40;
osg::Texture2D * map = new osg::Texture2D;
map - setTextureSize (width, height);
map - setFilter
Hi,
for an RGBA texture you would need data to be of size width*height*4.
Also, not sure what your magic 4 is in image - setImage. Put GL_RGBA
instead of 4.
Try:
image - setImage (width, height, 1,
GL_RGBA,

Hi Robert and OSG community,

OSG 3.0 RC2 in Release mode was built fine here on Debian Testing
x86_64, using g++ 4.6. I just got lots of warnings like
warning: variable ‘xyz’ set but not used [-Wunused-but-set-variable].

There is rather too little detail about the performance you are
seeing, how many text items you have, how many you are change per
frame, whether you've compiled with debug and are profiling this, what
platform you are working with, what you hardware is, what happens to
your update, cull

Hi Tamer,
Thanks for spotting this regression. The bug came about due to me
tightening up the event traversal so that it only handles events
uptill the viewer.advance(), which prevents events having negative
times w.r.t the frame event. Unfortunately this fix meant that no
events were being

Forgot to mention that this fix is now checked into svn/trunk and the

NodeVisitor's subclasses are meant to only override the methods they

The documented problems which the warning issue relate to aren't

practice just a distraction that
HI David,
When the ray intersects a triangle it provides the three vertex
indices and the associated ratios are the baricentric coordinates
that you can use to compute the interoplate vertex, colour, tex coord
etc. There isn't an sorting of the indices to report the nearest.

Could run a debug build and get a stack trace from the crash and then

Also what movie plugin are you attempting to use to play the movie?
