Yeah, I played around with it a couple of years ago, but I ended up writing my own OpenCL wrapper because my code needed to run separately from Qt. There are some really nice ideas in there though. I expect it should work with Qt 5, maybe with a few minor alterations to some headers. At the very least it should have some nice examples of how to use OpenCL with Qt objects, such as QImage. > > Thanks! > > ------------------------------------------------------------------------ > *From:* Paul Miller <stel...@gmail.com> > *To:* interest@qt-project.org > *Sent:* Wednesday, March 12, 2014 3:38 PM > *Subject:* Re: [Interest] Qt and OpenCL crash course > > On 3/12/2014 2:08 PM, Jason H wrote: > > > I need to do some elementary graphics operations on QPixmap or QImage.
