Nut Graphics Engine

Description

The Nut Engine is a lightweight and modular graphics engine designed to facilitate the development of 3D applications using OpenGL. It abstracts the complexity of OpenGL setup and rendering, providing a simple interface for loading models, shaders, and rendering scenes. The engine is built with C++ and utilizes GLFW for window management and GLM for mathematics.

Features

• Model Loading: Supports loading and rendering 3D models.
• Shader Management: Allows for easy integration and management of vertex and fragment shaders.
• Camera Control: Implements basic camera movements and view transformations.
• OpenGL Integration: Simplifies OpenGL initialization and rendering processes.
• Extensible Architecture: Easily add new features and extend functionality.

Requirements

• C++17
• CMake (version 3.10 or higher)
• GLFW (included in external folder)
• GLAD (included in external folder)
• OpenGL

Building the Project

To build the project, follow these steps:

1. Clone the repository or download the project files.
2. Open a terminal and navigate to the project directory.
3. Create a build directory:

   mkdir build

4. Compile the project:

   make

5. Run the application:

   build/app

Usage

To use the engine, create an instance of the Engine class and call the render method with the path to the model you want to load. For example:

Engine engine;
engine.render("path/to/your/model.obj");
