This is an experimental OpenGL graphics engine designed to test and implement various cutting-edge technologies in computer graphics. The engine serves as a testbed for exploring and validating different approaches and algorithms.
Collision Detection
Octrees are employed for efficient collision detection.
The engine supports custom collision meshes and automatically assigns a fitting sphere collision to each model.
Collision Response
Each object is assigned a rigid body to determine its behavior in the virtual world.
Currently, the engine implements a bounce response, but the rigid body class is easily extensible to accommodate various types of responses.
Ray Collision
The engine includes a ray collision system. The current response is to delete the hit object, but it can be easily modified based on specific requirements. Users can emit rays by clicking the left mouse button.
Input System
The engine utilizes a classic OpenGL callback input system for handling keyboard, mouse, and joystick inputs.
Shaders and Shadows
The engine currently supports base color and normal textures.
Tangent space is calculated for normal maps, and the normal texture effect can be toggled on/off by pressing 'N'. Global illumination (ambient, specular, diffuse) is implemented. Blinn-Phong lighting model is used and can be disabled by pressing 'B'. Skybox is implemented using Cubemaps. Three types of lights are supported: Point Light, Spot Light, and Directional Light.
All light types have shadow maps (Spotlight shadow is currently not working properly).
Scene Class
The Scene class allows the creation of unique scenes with different parameters and frame buffers.
It serves as the main function to create new scenes and environments. Save functionality and object movement with gizmo UI are planned for future implementation.
Rigs and Animation
Rig and animation systems are currently in the TO-DO list and will be added in future updates.
The engine's development has been guided by the OpenGL tutorial series available at: https://github.com/michaelg29/yt-tutorials/tree/master/CPP/OpenGL. A significant portion of the codebase has been inspired by and adapted from this valuable resource. It aims to provide a flexible and extensible framework for experimenting with advanced graphics techniques and algorithms. It serves as a learning tool and a foundation for building more sophisticated graphics applications.
Contributions, feedback, and suggestions are welcome as the engine continues to evolve and incorporate new features. The goal is to create a robust and feature-rich graphics engine that can be used for various purposes, from educational projects to commercial applications.
