A 3D game engine written in and for Java. Many features including collisions, particle systems, shaders, terrain system, renderer abstraction.

jMonkeyEngine (jME) is a game engine made especially for modern 3D development. The entire project is based on Java for high accessibility. Advanced graphics are supported through OpenGL 2 via LWJGL.

The technology is considered a low-level game development tool. As a collection of libraries, jMonkeyEngine hardly imposes any limitations on programmers, while increased user-friendliness and optional frameworks are applicable in use with the jMonkeyPlatform.

jME is a community-centric open source project released under the new BSD license. It is used by several commercial game studios and educational institutions.

Features

jMonkeyEngine is written 100% in Java, which sets it apart from the majority of other game engines. This makes for a unique target user group of Java game developers. The code requires minimal adaptations for cross-compatibility and can sit on top of any OpenGL 2-ready device running the Java Virtual Machine. The engine is built with a shader based architecture to comply with modern graphics standards.

The development philosophy behind the jME3 core is to bring all game development essentials straight out of the box, while every included library can just as well be replaced by another, creating a neat modular structure
