(Question) Perturbation Theory works! However...
« on: November 10, 2020, 12:56:07 AM »
There's an issue that I've been facing for weeks now. The image you see attached is what I'm talking about. Screen jitters at around 10e16. Is there any code that fixes this problem?

You need a higher precision type than "double" for the center coordinates and reference calculations at that point.

How would I since there's no higher precision type than "double" in OpenGL?

You could calculate the arbitrary percision reference on CPU and pass the datas to GLSL as a texture ??? and using newer GPU should have double precision.

edit: the only way to do it all on the GPU is with some specialized code using one of the available libraries.
