j3D is a lightweight, Java-based 3D game engine built with LWJGL and OpenGL.
- Modern OpenGL Integration: Utilizes LWJGL for efficient OpenGL bindings
- 3D Model Loading: Import and render OBJ format 3D models
- Texture Support: Load and apply textures to 3D models
- Lighting System: Primitive lighting with ambient, diffuse, and specular components
- Camera Controls: First-person camera with freecam for development
- Scene Management: Organize and manage entities in scene graphs
- Performance Optimization: Efficient rendering pipeline and resource management
- Cross-Platform: Works on any platform supporting Java and OpenGL
- Java 11 or higher
- System that supports OpenGL (most of them)
- Gradle
To launch the j3D application suite:
# Using Gradle (recommended)
./gradlew run
# Using the shell script
./launch_j3d.shThe launcher provides access to:
- j3D Engine: The main 3D game engine
- jEDIT Level Editor: 2D level editor for creating 3D levels
The launcher automatically handles the required -XstartOnFirstThread JVM argument for proper OpenGL context creation on macOS.
