GLSL Nodes for ComfyUI

This nodes add support for GLSL shaders on workflows, by adding the following nodes: glslEditor, glslViewer, int, float, vec2, vec3, vec4.

Here some examples:

examples/types.json types

examples/depth_of_field.json

examples/edge_detection.json

examples/look_up_table.json

examples/raymarch_to_image.json

examples/raymarch_buffers.json

examples/video_flow.json

examples/video_mask.json

examples/video_dither.json

examples/video_pixelate.json

examples/shadertoy.json

Features:

It the code is compatible with GlslViewer, Glsl-Pipeline and GlslCanvas by following the following specs for:
- Uniforms
- Defines
It contain LYGIA Shader Library by resolving all #include directives from LYGIA's Server

Roadmap

[x] 100, 120, 130, 140, 150, 300, 330, 330 core, 400, 410, 420, 430 and 440 GLSL shaders
[x] Resolves dependencies to LYGIA Shader Library
[x] Code editor (ACE) on GlslEditorPro nodes
[x] produce multiple frames
[x] reads multiple textures and texturesArrays
[x] multiple float, vec2, vec3, vec4 uniforms
[x] Dynamic inputs for uniforms
[x] Uniforms node for efficiency by caching textures and texturesArrays together with the GL context
[x] basic GLSL type nodes: int, float, vec2, vec3 and vec4
[x] 2D position node widget
[x] 3D position node widget
[x] Color Picker node widget
[x] multiple buffers (#ifdef BUFFER_X)
[x] multiple double uniforms (#ifdef DOUBLEBUFFER_X)
[ ] multiple pyramids (#ifdef PYRAMID_X)
[x] OPTICAL_FLOW textures
[x] MASK textures (create SDF on other channels)
[ ] loading 3D geometry
[ ] Vertex Shaders
[ ] CubeMaps (Auto detect equirectangular, cross, etc)
[ ] BACKGROUND pass (#ifdef BACKGROUND)
[ ] POSTPROCESSING pass (#ifdef POSTPROCESSING)
[ ] SCENE pass (#ifdef SCENE) that exposes u_scene and u_sceneDepth
