arisu

A painting program implemented entirely from scratch in LuaJIT.

Requirements

• Linux (Recommended) or Windows
• Support for OpenGL 4.3 (you most certainly have this)
• That's it.

There are no dependencies used by the library. Pure X11/Win32 and OpenGL.

Goals

• Fast
  • Best practices in the GPU pipeline and when writing LuaJIT code.
• Written from scratch
  • Zero dependencies
• Implement all painting operations on the GPU
  • Canvas is stored on the GPU and manipulated purely with compute shaders

Showcase

Running

1. Set up LuaJIT on your system
   • Windows: winget install -e --id DEVCOM.LuaJIT
   • Linux: dnf install luajit or apt install luajit
2. Clone the repository
   • git clone https://github.com/codebycruz/arisu
3. Run this inside the repo folder
   • luajit ./src/main.lua

And yes, it needs to be LuaJIT, not Lua! FFI is extensively used. This repo basically uses C.
