CUDA Example - slower than expected?
Hi,
I don't have any other suggestions than to use a GL debugger to make
sure nothing is going to CPU or to try the new CUDA functions in osgPPU
or your own code. I remember something in the GL to CUDA stuff bugging
me, but cannot remember the details.
Thanks for the answers. Actually I also know that there are new
interoperability features in CUDA 3, but I didn't have the time to check
them out yet, though if I find the time for it, I will let you know
about the results :)
Regards

supports GPU<->GPU memory mapping, whenever you access to OpenGL textures there
is a full memory copy performed.

Ok..I correct this: There is a difference of ~1 frame ;) ...now I will
stop replying to my own messages :D

Hi,
as I explained in some other mail to this list, I am currently working
on a graph based image processing framework using CUDA. Basically, this
is independent from OSG, but I am using OSG for my example application :-)
For my first implemented postprocessing algorithm I need color and dept
