Sparrow OpenGL Renderer

A Tiny OpenGL Renderer Playground in C++.

Build and Run

mkdir build
cd build
cmake ..
cmake --build .

Roadmap

This project is currently in a chaos, most of the code made me shamed. The only reason I make it currently now is that I need to refer it in my own coursework.

FeatureList

• Basis
  • Forward Rendering Pipeline
  • Skybox
  • Model Loading(GLTF / FBX / OBJ)
  • Multiple Scenes
  • IMGUI UI Controls
  • Input and Window System
  • Camera System
  • Automatic Multiple Texture
• Rendering
  • OpenGL RHI( still in processing strictly...)
  • Simple Triangle (Scene01_Triangle.hpp)
  • Forward Albedo PBR (Scene_LoadModel.hpp)
  • Forward Bloom (Scene_LoadModel.hpp)
  • Forward SSAO (🐞 in repairing)
  • Forward IBL (🐞 in repairing)
• Animation
  • BVH Viewer(Scene_BVHView.cpp)
• Simulation
  • Cloth Simulation(Scene_ClothSimulationSS1.hpp & Scene_ClothSimulationSS2.hpp)

TODO WORKS

• Rendering Features
  • SSAO
  • IBL
  • Deferred Shading

Acknowledge

• Most of the examples followed by LearnOpenGL
• The original code framework followed by The Cherno
• Youtube OpenGL is a good project to learn how to implement OpenGL features in OOP mode
• Piccolo Engine is a good project with engine structure. Files like WindowSystem, LogSystem are copy from this project.
