SPIRV-VM VS SHADERed

It uses https://github.com/dfranx/SPIRV-VM for stepping through but that could use some bugfixing and further development.

The debugger uses a SPIR-V VM I made ( dfranx/SPIRV-VM: Virtual machine for executing SPIR-V (github.com) ). It basically runs shaders on CPU.

If you specifically want to learn shader programming then https://shadered.org/ is a lot more practical than Shadertoy.

I recreated this shader in SHADERed, and if you're interested, you can view its implementation and experiment with your own parameter values and textures. The project can be downloaded here.

There's http://shadered.org/ but it's abandoned now.

That’s why I recommend https://shadered.org/ instead for people who want to learn to use shaders in common contexts.

https://github.com/dfranx/SHADERed (useful tool for debugging shader code, has a bit more functionality than doing it in Godot directly)

https://shadered.org/ spent much time on basic editor features like Intellisense and now it seems to be dead. The time would have been better spent fixing/improving the core features like the awesome debugger. Only very late they added a (basic) VSCode integration.

Hi corysama, thankx for the comment, there is some truth to that yes for sure. As in, in games you writes more vertex / pixel or "surface" shader and then geom, compute. But I have to somehow disagree in terms of lighting. Sure this is raymarching so geometry is procedurally made in the shader, whereas in game shader it is passed with polygonal 3d model. But the lighting / colour shading calculation are the same as with polygonal geometry (ndotL for diffuse pow(max(reflect(dot(-ld,no)... for specular, calculating normals on fly in shader, etc...) so in that respect it will help for game dev style of shaders. Also I would argue that a lot of animation technique and vfx technique in raymarching shaders are similar / useful / reusable with polygonal geometry, like yanimation based on clamping sin and doing easing etc. Therefore doing raymarching shaders is good for becoming vfx artist / technical artist I guess. You are right though to point out the difference, that's clear. Good shout about shadered.org as well. Cheers!

Hi, is there a plugin that supports using SHADERed IDE to write unity shaders? It has a lot of functionalities than a standard editors and I it can save a ton of time for me. Have already searched the google but have not found anything.
