(Just a few common gotchas here)
1. Have you disabled the dlistcache for the geom?
2. Are you doing any multi-aspect work and forgetting to clear the
changelists?
Best regards,

Hi everybody,
I have a problem with memory leaks. I'm programming a particle system.
And for that particle system I use a geometry, where I store my
positions of the particles. My particles look like small arrows
(triangular), and I use the geometry as type = GL_TRIANGLES and with a
length between 100 and 5000 particles (traingles).
To move the particles, I don't use a transform, because I would need a
Geometry, a Node, a Transform, a Transform Node (and so on) for each of
the 5000 traingles and that would need to much memory. What I'm doing
instead, is, that I get the current position and set the new position with
begin (_partPos);
_partPos->setValue(Pnt3f(x,y,z), i);
end (_partPos);
where i is the number of the current particle (_partPos is a
GeoPositions3fPtr Object) and x,y,z is the new position.
And now my problem: Everytime I'm animating my particle, my memory usage
increases slowly, especially when I first reset my particle and the
geometry and call clear() on every component of the geometry and then
add new points to the geometry.
I even tried some other solutions like
_partPos->getValue(i).setValue(Pnt3f(x,y,z));
but nothing changed.
Why, has anyone an idea?
Bye, Oliver
