A demonstration project for learning and experimenting with GPU shaders using OpenGL. This project provides simple examples to understand how to implement and use shaders in graphics programming.
This project showcases various shader implementations using OpenGL, GLEW, and GLFW. Each example demonstrates different aspects of shader programming, starting with basic concepts like rendering a simple triangle.
To build and run this project, you'll need:
- C++17 compatible compiler
- CMake (minimum 3.10)
- OpenGL (3.3+)
- GLEW (OpenGL Extension Wrangler Library)
- GLFW3 (Graphics Library Framework)
It's recommended to use vcpkg or similar package managers:
- Clone the repository:
- Create and navigate to build directory:
- Generate build files with CMake:
- Build the project:
The project includes several examples, each demonstrating different shader techniques:
A simple example showing a colored triangle rendered with basic vertex and fragment shaders.
To run this example:
This example demonstrates:
- Setting up an OpenGL context with GLFW
- Compiling and linking vertex and fragment shaders
- Creating and using vertex buffer objects (VBO) and vertex array objects (VAO)
- Drawing a basic shape with a solid color

- Press ESC to close any example window
- Window can be resized, and the viewport will adjust accordingly
To add a new example:
- Create a new .cpp file in the examples/ directory
- Add the example to CMakeLists.txt using the add_example() function
- If needed, add any shader files to the shaders/ directory
