GraphicsProgramming Playground (OpenGL)

A personal OpenGL learning playground written in C++.

This repository contains small, isolated OpenGL examples and exercises implemented while following
LearnOpenGL (https://learnopengl.com/).

The main goal of this project is to build a solid intuition about graphics programming fundamentals by working on focused, minimal examples instead of large frameworks or engines.

This is a learning playground, not a game engine or reusable framework.

✨ What’s Inside

• Standalone OpenGL examples (triangle, RGB interpolation, square with EBO, exercises, etc.)
• Each example focuses on one core concept
• A simple console runner to switch between examples easily
• Built using CMake with dependencies managed via vcpkg

🧰 Dependency Setup (vcpkg)
1) Install vcpkg (one time)
cd C:\
git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat
2) Install required libraries
.\vcpkg.exe install glfw3 glad
  For x64 explicitly:
  .\vcpkg.exe install glfw3:x64-windows glad:x64-windows

🏗️ Build Instructions
From the repository root:
cmake -S . -B out/build `
  -DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/scripts/buildsystems/vcpkg.cmake

cmake --build out/build

▶️ Running the Examples
.\run.ps1


📚 Learning Source

This project follows the structure and exercises from:

LearnOpenGL
https://learnopengl.com/

Examples are reimplemented manually to better understand:

buffer management

vertex attributes

shaders

draw calls

basic OpenGL state handling
