Hi I've been trying to import this Shadertoy, https://www.shadertoy.com/view/lsG3zK
I have it almost working, and the buffering is wired up correctly I hope - but the ripples / waves on my version dissipate almost immediately. I've attached a comparison screenshot. I'm wondering if differences in interpretation of GLSL code are the problem. It seems to be something to do with how the color / height values are being read / written.
Does anyone have any clues ? Thanks, Glenn.
To summarize from the comments — These shaders require 32bpc color depth. Vuo 1.2.3 only supports up to 16bpc.
@glennmarshall, thanks for confirming that it works in OpenFrameworks.
In our code under development, we added experimental support for 32bpc and confirmed that the composition renders correctly. We'll follow up on feature request 32bpc Color Accuracy.
