This is really interesting me. But I don’t yet understands why the gaussians for each sample would need to be anisotropic. At least in my limited understanding the samples are drawn from microlenses which more or less look like something between hemispheres and squares which should be isotropic. If you have some pointers for me on where to get more information I’d be very interested.
I saw that too but my suspicion is that that’s just a ‘marketing’ image. I’d be surprised if they could actually reconfigure the CFA.
