Sure! Is webgl good enough for you? If so, I will prepare an example and include it in the official release. If you need more "standard" GPU power, then it will be possible, but a little bit hackish on the beginning (we don't have libraries for it yet and you will need to connect to other language to keep the performance. We will support language interoperability, but in the first reelease it will be hackish. Still if you'll need it, I'll show you how to do it) :)
So do you have first-class support for video as well as images? It seems like to have fun with video editing in Luna, you'd need to have built-in support for videos an inputs and outputs, and have a way to play the video output on the screen, and maybe scrub through it, and at a minimum be able to run shaders on the "current frame" and export the resulting video out. The next level after that would be being able to load multiple frames into memory at the same time, and being able to do a combination of "offline" and "online" processing with some CPU involvement (e.g. calculating a motion track and storing it, or applying a filter that can't be expressed as a pure shader program).
I don't know enough about Luna yet to know what code to do these things would "look" like on the visual side, or come to think of it where the computation is being performed (in the browser?). Much more to learn, but the project looks great, a sort of "holy grail" in a way.
Hi! Thank you for such great description of the process. In fact I know it well, I originate from the same domain - i was working for few years as FX TD :)
You can think of Luna just like about a general purpose programming language. You can define your own types and you can even define how to decode bits from binary files to your structures. The GUI runs in HTML, so you can utilize any html component to display output. Definitely, your use case is doeable, however the amount of libraries currently available is very, very low, so it will need some love :)
