Hi Frank

I would do a search of the OSG mail archives, your questions have been
answered several times and within the last few days

The blip you see is that your textures are downloaded to OpenGL the first
time they are drawn in the visible frustum . Again there is a solution in
the mail archives


Simply do a google 'OSG share textures' or google 'OSG scale textures'
etc...

Subject: [osg-users] Some texture questions

Hi,

I just have some basic questions about textures, and I was hoping someone
might have an answer to them:

1) Right now, I have several objects that refer to the same texture file. Is
there any way to make sure that these objects, when loaded, share the same
texture object in memory, rather than loading the same texture multiple
times?

2) It seems as though the system might use a sort of lazy loading scheme for
the textures. I'm not 100% sure about this, but when I first load my scene
and move the camera around, I notice that there is a frame rate hitch
whenever an object is being displayed for the first time. Once I've viewed
all the objects at least once, then there are no more hitches. I could be
wrong, but I also noticed that some of these objects have non-power-of-two
textures, and these hitches correspond with a console message that says
"Scaling image x from (800,800) to (1024,1024). So, that's why I suspect
that maybe the textures are being loaded when they first appear, rather than
when the model is loaded. If so, can this be turned off?

Thank you!

Cheers,
Frank
