CG Workbench

The CG Workbench is a small GLSL coding environment which allows to rapidly prototype some shaders or shader pipelines.

Live Shading Demo: Youtube

Controls / Usage

Right-Click on a node	Open node editor (save to template, rename node)
Ctrl + Left Mouse + Drag	Drag viewport window
Ctrl + R	Recompile current window
Ctrl + S	Save
Ctrl + Shift + S	Save As
Ctrl + N	New document
Ctrl + O	Open File

Build Instructions

CG Workbench uses Zig as a build system. Just call zig build to build your project, zig-cache/bin will contain the executable.

Linux

Install the following libraries / packages:

• sdl2
• gtk-3.0

Windows

Should work out of the box

External Libraries

This project would be much harder without those great libraries:

• SDL2
• GLM
• github.com/nlohmann/json
• github.com/skaslev/gl3w
• github.com/ocornut/imgui
• github.com/mlabbe/nativefiledialog
• github.com/nothings/stb
• github.com/syoyo/tinyobjloader
• github.com/cxong/tinydir
• github.com/severin-lemaignan/webcam-v4l2

Ideas / Missing Nodes

• Save query when creating new node with existing content
• Shader Common Node
  • Provide "includes" for all shaders
• Graphic Nodes
  • Geometry Node
    • Primitives
      • Sphere
      • Cube
• Player-Modus (lädt jgraph-File und hat ein Haupt-Renderer)
• Event-Delay Visualisierung
• Buffer -> Texture
  • 1D Input/Over → 1D Texture with n width
  • 2 * 1D Input/Over → 2D Texture with n * m width
• Input Node
  • Keyboard
  • Mouse
  • Joystick
• Lua Node
  • SetUp
  • Update
  • Shutdown
• Sound Node
  • Seek (?)
• Timeline Node
  • Attach values to a timeline
  • Time as input
• Synth-Kram mit T$
• LUT-Node
  • Maps input→output by indexing a table
• Audio Nodes
  • Signal Mixer Node
  • Envelope Generator Node
