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.

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
