[jitter] Re: Moving planes efficiently in OpenGL

I am currently using poly~ to create and control 16 copies of the plane. This keeps things tidier but I don't see any increase in efficiency.

Using 1 x videoplane with 16 controls - would this be any more efficient than having 16 individual planes? I imagine so to a degree. I'll give it a go. 

Sketch I have little experience with so that could be a possible area of investigation.

I can certainly see the merits of using javascript, the only downfall is my knowledge of the language. I'm hopefully going on a javascript workshop soon which will be enlightening.  

My main thoughts around this subject are ones of bewilderment. I can't believe how awkward it is to efficiently move what are effectively 16 sprites around a screen (or is it that I just don't know what I'm doing - I guess not). I have a little experience with "sketch" languages such as "Processing" where doing the sort of thing I am trying to do would be easy - the only downfall is that it doesn't offer a lot of the other things I require my app to do.

Fortunately I have managed to use all your advise (cheers guys) to tweak my patch so it works to an acceptable level.    

Thanks a lot
