        # CG Workbench

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

## Build Instructions

CG Workbench uses [Zig](https://ziglang.org/) 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](https://www.libsdl.org)

- [GLM](https://glm.g-truc.net/0.9.8/index.html)

- [github.com/nlohmann/json](https://github.com/nlohmann/json)

- [github.com/skaslev/gl3w](https://github.com/skaslev/gl3w)

- [github.com/ocornut/imgui](https://github.com/ocornut/imgui)

## 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
