Hi, I was wondering if anyone would be able to point me in the right direction
as to how to add support to load custom file types not currently supported by
OSG. I've been looking for a while and haven't turned much up that appears to
be of use.
Thank you!
Cheers,
Peter

Hi Peter
I have no personal experience with this, but from my understanding the most
correct pattern would be to add a new plugin for your file type. Take a look
at the way other files are handled either images like bmp's or models.

An interesting result. I'm afraid I can't recall the reason for the

it's pretty likely it was an attempt to improve one aspect of

Wang Rui,
Looking at gl.h under the different SDK's here are the typedefs:

So I'm not sure what that means in terms of being able to support
different types with the serializer.

The way that OpenGL drivers work is that there is an OpenGL FIFO per

GPU, so
