Chess2RT

A raytracer renderer, written in D, which will eventually be used for a 3d rendered chess game (and/or a variation of it).

What works

• Simple geometry objects: spheres, cubes and a horizontal plane.
• CSG combinations of supported geometry objects (including CSG objects).
• Procedural textures.
• Lambert and Phong shading.
• Loading scenes from .sdl or .json files. You can find sample scene files in data/.
• Interactive camera movement (←, ↑, →, ↓ for movement, Shift + ←, Shift + ↓, Shift + →, Shift + ↓ for mouse look, Ctrl + ←, Ctrl + → for rotation and Ctrl + ↑, Ctrl + ↓ for up and down moving).

Build Instructions

1. Install what's needed (if you haven't yet):

   • D compiler with frontend >= v2.071.1 (e.g. DMD)
   • dub package manager >= v1.0.0
   • SDL 2 binaries >= v2.0.0 (SDL 2.0.3 DLLs are included for windows)

2. Git clone:

   git clone https://github.com/ZombineDev/Chess2RT.git
   

3. Run DUB:

   cd ./Chess2RT
   dub
   

Scene files

Scene files are written in SDLang or JSON and are usually put in the data/ folder. To render a specific scene you can either:

• call the app from the command-line like this:

  ./Chess2RT/bin/<OS>/chess2rt --file=data/scene1.sdl
  

• place the path to scene you wish to load in data/default_scene.path and call chess2rt without arguments.

Compatibility

	Linux	Windows
DMD 64
DMD 32
LDC 64

• DMD (reference D compiler) >= 2.071.1
• LDC (LLVM D Compiler) >= 1.1.0-beta2.

Acknowledgement

I developed this project for the 3D Graphics and Raytracing course at fmi.uni-sofia. Most of the code in ./source/rt/ is based on https://github.com/anrieff/trinity/.

This project uses:

• SDL 2 (SDL 2.0.3 binaries for Windows x86 and x86_64 are included in lib/)
• GFM (package on http://code.dlang.org)
• SDLang-D (package on http://code.dlang.org)
