Updating surfaces from javscript

[ryanhammonds]

Hi! Thanks for the package.

I am initializing a fsaverage surface and displaying:

vertex = cortex.Vertex(np.zeros(327684), "fsaverage") cortex.webgl.make_static(outpath='viewer', data=vertex)

Then I have javascript that computes the a Float32Array client side, based on user input. I want to update the surface after the page has been created. Any suggestions on how this may be possible? I can do it if I precompute png files. But since I'm generating the array with javascript, I don't have write access from the front end after the page is served. I will keep hacking at this and will post a solution if / when I find one.

Thanks!
