Hello list,
This is purely speculative but I'd love to hear people's thoughts on this, particularly pointers to what would be the best ways to proceed.
What if I had a massively powerful Mac Pro with the maximum number of graphics cards in it, each DVI output going to a different hi-res projector? These projectors are arranged so that they overlap slightly, perhaps in weird orientations and angles! Each screen outputs one portion of a single Quartz Composer composition, and the magic application that does all this handles edge-blending and warp distorting each of the screens and synchronising rendering so that they are all magically perfect.
Those in the know will recognise this as something a bit like WATCHOUT, except I'd like to see it done with Quartz Composer on Mac OS X thankyouverymuch. It's also pretty close to what Quartz Composer Visualiser does at the moment (except without the smartypants edge- blending and so on).
Q1.Whats the maximum number of DVI outputs I can reasonably pack into a single computer these days and expect decent performance using QCRenderers? 4 x dual DVI outputs (ie. 8?) - Can this figure be any higher? Any recommendations on what cards I should look at?
Q2.Whats the maximum number of QCRenderers I can reasonably run on a single machine? Or can I do something smart like have 1 renderer for the entire composition and split it's output, post-processing the edge- blending and warp distortion? I think not, but it's an idea.
Q3.Would it be better to go for a distributed, multi-computer setup instead of one-machine-does-it-all? I like QCV's approach of handling both effortlessly.
Q4.Who on this list with the appropriate Cocoa/OpenGL/Wizardry skills might be interested in being hired to help make something like this happen? At this stage there's no guarantee this might happen, it's just a speculative idea for now. However, drop me a line off-list if you think you'd be interested.
Okay - that's all for now. Thanks for listening to my braindump! Best, Ade.
