Original Source: http://feedproxy.google.com/~r/tympanus/~3/FDQVPCkh4Lo/. Theres no way in the shader to do something like every 4 quads since its a post process effect. This is pretty much the same as regular HTML in that JPGs have lossy compression, than reading 1 pixel and blending. They go at the same speed, but start at different times. Basically you want a lower normal multiplier, so that only sharper changes in surface have an outline, but smoother changes are not visible. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. try this. each of the 4 pixels.
