Hello all
I’m using a fragment shader to compute fractals, so I’d like to use doubles in the shader. However the PShader.set() method for setting shader uniforms only supports float. Can anyone suggest how I can set a double? My fractals are getting blocky too quickly!
Thanks,

Hi, thank you for your reply. I’m not sure how to proceed. Are you suggesting I open an issue on GutHub?
If that’s the case, I will. I would welcome any ideas for a workaround too.
Thanks,
Yes! if you look up inside the PShader class you won’t find any mention of double there:
/* -*- mode: java; c-basic-offset: 2; indent-tabs-mode: nil -*- */

But I believe it’s feasible for the devs to add double functionality for PShader .

Thanks for clarifying. I’ll open an issue. Having looked at the code, adding double seems straightforward technically.
cheers!
