[util] shadertoy shader effect viewer

[Alexar]

hi guys,
these days, i am very interested in playing with shaders. and i found the site http://www.shadertoy.com.
you can see these amazing effects 2d & 3d. the language in that site is a little different from love's, so i desided to do some conversion.
with this util, you can run the code copied from shadertoy directly, or you can output the converted code to love shader.
here are some screen shots.

for now, this util dont support the texturecube function and vr function, and the channel sources are limited to image files(shadertoy supports sound and video).
this util is for easy shader learning in love, you can use it freely, but all right of the oringal shaders reserve to the orignal shader coders. i will delete it if any infringement.

That's incredibly useful! I like checking out shadertoy too periodically, but was slightly disappointed at the lack of usage within Löve, but now that's been resolved! Thanks a bunch!

This is quite awesome and useful.

thanks for support, hope you enjoy it.

WOW!
Alexar, this is awesome. shadertoy.com has a lot of good examples (2d shadows, gradients, fractals, ...)
Thanks!

Where you get raycast2d.glsl ? I can't find this on shadertoy.com.

Is it just me, or should the mouse-controlled light source in the raycasting example move with the mouse cursor, and not mirrored horizontally and vertically? Because it moves like that on my end :v

sorry,it's my mistake, and fix that by

Code: Select all

    iSystem.iMouse[1],iSystem.iMouse[2] = love.mouse.getPosition()
    iSystem.iMouse[1]=resolution[1]-iSystem.iMouse[1]
    iSystem.iMouse[2]=resolution[2]-iSystem.iMouse[2]

i changed the file name, the origin name is something like "distance based 2d soft shadow", i forgot.

This was very broken when I tried it. I'm pretty sure a lot has changed since this version of love so now this code looks pretty bad.
I updated it to 11.3 and made it work with pre-converted glsl code.
You can also change the resolution by changing the window size now.
Arrow keys switch between shaders. It will skip any that can't compile (which is several).
Enjoy!

I couldn't help it, I added a bunch more example shaders from shadertoy.com
Mouse inversion is fixed now forgot about that the first time lol
