3DWorld: A Cross-Platform Procedural 3D Game Engine Powered by OpenGL

3DWorld is an innovative and powerful cross-platform game engine designed for creating immersive 3D environments using OpenGL. Developed since 2001, this game engine facilitates a range of procedural content generation methods to bring dynamic worlds to life, including terrain, cities, and galaxies.

Key Features:

• 3D Graphics Functions: Comprehensive classes and wrappers around OpenGL to empower developers.
• Shader Generator: Includes a hot reload feature for efficient shader development and integration.
• Procedural Content Generation: Generate a variety of elements including terrain, vegetation, cities, and building interiors and exteriors.
• Dynamic Universe Creation: Create expansive universes populated with galaxies, stars, planets, and moons.
• Voxel Terrain Editing: Offers real-time user editing for 3D voxel-based terrain.
• Advanced Physics Simulation: Supports primitive object types with the capability to handle over 10,000 dynamic objects simultaneously.
• Real-time Weather and Day/Night Cycles: Implement weather effects such as rain, snow, hail, and lightning.
• Physically-Based Materials: Materials simulate reflection and refraction effects realistically.
• Lighting Effects: Up to 1024 dynamic light sources, along with dynamic shadows and ambient occlusion.
• Comprehensive Animation Support: Features skeletal and procedural animation.
• Built-In Games: Includes a first-person shooter titled "smiley killer" and a spaceship colonization game.

Procedural Generation:

3DWorld's unique procedural generation algorithms can create:

• Intricate Building Designs: Generate both interior and exterior building layouts.
• Comprehensive Urban Environments: Form entire cities with realistic road networks and infrastructure.
• Evolving Natural Landscapes: Design terrains with various noise functions and erosion models.

System Requirements:

• Operating Systems: Compatible with Windows 8, 10, 11, and Linux (with GCC).
• Development Tools: Microsoft Visual Studio 2019 or 2022 required for project files.
• Hardware Requirements: A modern NVIDIA or AMD GPU is recommended, with at least 8GB of system memory and 4GB of GPU memory for optimal performance.

Additional Resources:

• 3DWorld Blog: Explore a blog with detailed descriptions and visuals of the algorithms used in 3DWorld: 3DWorld Blog.
• Screenshot Gallery: The blog also features an array of images demonstrating the engine's capabilities, including procedurally generated environments and effects.

Educational Use:

3DWorld is developed for educational purposes under an open-source license, welcoming feedback, bug reports, and suggestions. Use of resources for personal projects is permitted, and contributions are appreciated as the project progresses.

Example Usage:

To kickstart development with 3DWorld, configure your settings through the command line:

./3DWorld config_filename.txt

This enables a customized game experience based on selected configurations.
