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
