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

• 100, 120, 130, 140, 150, 300, 330, 330 core, 400, 410, 420, 430 and 440 GLSL shaders
• Resolves dependencies to LYGIA Shader Library
• Code editor (ACE) on GlslEditorPro nodes
• produce multiple frames
• reads multiple textures and texturesArrays
• multiple float, vec2, vec3, vec4 uniforms
• Dynamic inputs for uniforms
• Uniforms node for efficiency by caching textures and texturesArrays together with the GL context
• basic GLSL type nodes: int, float, vec2, vec3 and vec4
• 2D position node widget
• 3D position node widget
• Color Picker node widget
• multiple buffers (#ifdef BUFFER_X)
• multiple double uniforms (#ifdef DOUBLEBUFFER_X)
• multiple pyramids (#ifdef PYRAMID_X)
• OPTICAL_FLOW textures
• 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
