Hi,
I've recently been fiddling/debugging with a similar setup, nl RTT to
osgCuda. From what I've seen in the code (r314) the copy step is missing
for osgCompute::MAP_DEVICE_SOURCE. Allocation of a copy happens, but if
the texture does not have an osg::Image, no sync is taking place.
Sending my test app to the osgCuda devs is on my todo list that does not
seem to want to get shorter. I was also not sure if I have to attach
some kind of callback.

Hi,
Is there any fix or workaround for this that you've found?
No, I haven't had time to look at this further. I expect that a
cudaMemCpy from the RTT texture to the allocated osgCuda copy will fix it.
