Summary

Project for EPITA (OM3D), flatland Radiance Cascades implementation in C++ using OpenGL.

Setup

Requirements: cmake 3.20 minimum, C++17, and OpenGL 4.5.

# At the project root
mkdir -p build/debug
cd build/debug
cmake ../..
make
./OM3D

Project structure

• src/main.cpp : Window, user inputs, GUI, pipeline steps (C++ part of the implem is written here)
• src/*.h & src/*.cpp : Helper classes (most of them unchanged from given codebase)

---

• shaders/flatland_draw.comp : Interactive drawing on screen from user
• shaders/clear_draw_tex.comp : Clear the draw texture
• shaders/flatland_jfa_seed.comp : Initialize seed for Jump Flooding Algorithm (JFA)
• shaders/flatland_jfa.comp : JFA Iteration based on seed to complete the final texture
• shaders/flatland_jfa_dist.comp : Conversion from JFA output to Signed Distance Field (SDF)
• shaders/flatland_raymarch.comp : Radiance Cascades implementation (should be named flatland_rc.comp)
• shaders/screen.vert & shaders/flatland_render.frag : Shader couple to display a texture on fullscreen triangle

---

The rest is legacy from other mini-projects that were done using this codebase prior to the RC implementation.

Sending much love to the Radiance Cascades discord community for proving so helpful and being lovely people :)
