I'm developing a series of patches for a live performance that generate sound reacting visuals (as usual).
For a specific section, I would like to use jit.bfg with Voronoi noise. The sound would control some aspects of if, specially the offset, scale and exp.
As it turns out, it works perfectly fine with a small matrix, such as 256 x 256. But in this project all content is in full hd and in this resolution controlling the noise is impossible, as it is really CPU intensive. I'm using a 15" MacBook Retina, 2.6Ghz i7, 16gb Ram with a NVidia GeForce 650M 1024MB.
Is there a solution? Can I use jit.bfg in a more efficient way? Or is there another way to achieve a similar looking result as Voronoi noise?
