A lightweight and easy-to-use 3D game engine.

Developed with the software and tools below.

Doodle Engine (WIP) is a lightweight 3D game engine crafted in C++ and OpenGL, designed to allow developers to create captivating 3D scenes and games as easily and freely as doodling. The engine is divided into two primary components:

• Doodle Engine: This core component manages rendering, input handling, resource management, and more, enabling developers to focus on creativity without getting bogged down by technical complexities.

• Doodle Editor: A user-friendly editor that facilitates scene and resource management, complete with preview and debugging capabilities. This tool empowers creators to visualize their ideas in real-time.

To enhance flexibility and ease of development, Python is employed as the scripting language, leveraging its robust ecosystem and simplicity. Doodle Engine embodies the spirit of creativity and exploration, allowing developers to experiment freely and bring their imaginative concepts to life.
