Title: Understanding how to create X type of Shader?
Post by: SFMLNewGuy on January 04, 2022, 03:48:08 am

I just had a quick question? How do people typically figure out different types of shader effects (2D)? Say you want an explosion, or a wind effect, or a fountain? How do people figure this out? Do they just find out the formulas that emulate X type of effect?

Is there a general place where you can find templates of just about anything you can think of? Like a plug-in-play almost where you can fiddle with the variables?

Thanks.

I found some examples online by googling webgl shaders… webgl-shaders.com had a rain effect in the fragment shader.  The other site comes to mind is shadertoy not that I’ve played much with shaders personally.

There are also tons of examples on shadertoys (https://www.shadertoy.com/).

You can also do the math to figure out how things need to be moved, but it's usually simpler to just find an example.
