Hi,
Don´t know if my question is a question concerning a "general" problem
or if its a problem concerning my data and my application.
Maybe somone had similar problems or an idea where I can look for a
solution.... Here we go:
The problem itself is very simple:
In my application I render a scene, which consists of a ground (which is
build from Geometry-Nodes and which contains some textures, basically
Image and Material pointers created on the fly) and where I can insert
additional nodes interactively. I can choose these nodes using a File
Dialog from Qt, then I get a filename (in this case I only choose
VRML-Files) and then I use the Scenefilehandler to get a NodePtr.
Then I add the NodePtr as a child to the rendered scene and update the
scene...
After having inserted some (dont know how much - about 5 VRML-Files with
textured objects, but how much textured objects are in the file?, dont
know) textured objects to the scene, the textures of every object I
will insert into the scene later, are not shown anymore....,
the object itself is there, but no texture on it. (The images are
definitely at the right path and are definitely referenced in the
VRML-File in the right way, because loading of the same object after
restarting the application results in a representation which is OK, what
means: with textures!)
It looks like ... "texture cache is full" or anything like that... Is
there any limitation concerning the number of textures or memory amount
used for textures in Open SG or OpenGL? If thats the case, is there any
possibilty to circumvent this limitations (even if you will loose some
performance?)
Any idea or suggestion?
Thanks a lot
Desiree Goerrissen
