Hi,
OSG provides an image processor class, it is used to compress and decompress
image, maybe you can use it.

A bug that has been niggling me for quite some time now is that under

The .ive format doesn't support the osgParticle NodeKit. The .ive

Hi everybody,
Just a quick question on changing render targets.
I have an osg::Camera with a Texture attached as render target.
Depending on certain conditions I want to detach the old Texture and attach a
different Texture.
My inital guess would be something like this:

H Dnaiel,
The normal way to manage rendering to multiple textures is to have two
different Camera, if you want to switch between these just using an

Hi Torben,
Yes, I was thinking along the same lines.
I was just having a peep at the source of decompress.cpp that comes with the
NVIDIA texture tools that might give a clue about the best way to do it. Which
seemed to boil down to:
Code:
nv::DirectDrawSurface dds(inputImageFile);
I don't understand what you mean.

If you build your scene graph manually: Use a transform node at the root of

If you only load a model: use the scale speudoloader.

Hi Robert,
Thanks for the clarification. I hadn't realised the compression was particulary
lossy as viewing the IVE files we are using (with compressed textures) seem to
have an acceptable quality for our purposes. But you are right, ideally it
would be better to keep the original textures,
Where can I find some literature on what a scale speudoloader is?
