Point conceded though. > http://people.mozilla.com/~sicking/webgl/juliaanim.html > http://people.mozilla.com/~sicking/webgl/mandjulia.html Neither of examples you posted seems to have the ability to zoom in, so I don't think they show anything about doing this to extremely high accuracy. But I see your point that much of this particular computation can be done on the GPU, up to probably quite high limits. Replace this example with your choice of non-data-parallel computation. Very sexy demos, by the way. Regards, Maciej -------------- next part -------------- An HTML attachment was scrubbed...
