ISF Shaders are extremely fast effect shaders ready to roll and open source, they run in GLSL so it’s Mac and PC. We could just copy and paste effects right into a cable project. The Code could be reviewed on ISF site or in the cables Doc quickly, the shaders are very, very fast. Shadertoy is a brilliant resource but the website is painfully slow to review ( I have a RTX 2080 and the website is still slow ), also shader adaptation is more complicated now that they are rendering to multiple passes and many shaders have mixed copyrights regarding usage. You can still find great stuff there and its definitely a great learning resource but sometimes you need a result yesterday and you dont want to get stuck reinventing the wheel, ISF shaders have a multitude of chain-able fx. Feebacks, a plethora of blur types, all fast. Just a suggestion.
Here is the resource:
