KlayGE/en

KlayGE is a cross-platform open source game engine with plugin-based architecture. It's started since 2003. The explicit goal of KlayGE is: to arm your engine with cutting-edge technology. It provides a framework to make game development, testing, porting as simple as possible.

Features

Graphics

• Deferred rendering-based
• Support DirectX 11.2, OpenGL 2.0-4.4 and OpenGL ES 2.0-3.1.
• Use FXML as the effect script for any renderable object. It can be exported directly from artist created content.
• Python script can be dynamic interpreted at run-time. So scripts don’t need to be recompiled after modification.
• Build terrains by height map technology.
• Support skinned animation.
• Hardware occlusion culling.
• Particle system.
• Post processing technology.
• Self-adaptive hardware states cache and deferred update mechanism.
• Support per-pixel lighting and rendering.
• Distance-based font system, takes advantages from both vector fonts and bitmap fonts.
• Support procedural texture.
• Support Sub surface scattering, which can be used to render translucency materials such as leaf, skin, jade-ware.
• Support Phong tessellation to smooth low polygon mesh at run-time.
• A material system for deferred rendering
• Shading

• A shader library includes common operations
• A complete interface abstracted from many low level graphics API
• Multi-pass rendering.
• Fully support of programmable shading
• Multiple input vertex streams is supported

• Lighting

• Dynamic lighting
• Omni-directional shadow mapping
• Realtime indirect lighting

Audio

• Audio output on many platforms.
• 3D audio source and Doppler effect.
• Ogg Vorbis as input format.
• Streaming playing

Tools

• Normal map generator, converts height map to normal map.
• Distance map generator, generates distance map from height map or 3D volume.
• MeshML export plug in, export models from 3DS Max.
• OpenGL compatibility checking tool.
• HDR compressor, compresses both cubemap and 2D HDR textures.
• Normal map compressor, provides 2:1 or 4:1 compression ratio.
• Distance-based font generator, converts a vector font to the format that engine uses.
• FXML2Shader tool, converts a FXML effect script to HLSL or Cg shader.
• Color Grading texture generator.
• Normals Fitting generator.

Programming

• KlayGE is open sourced. Includes all the source code of engine and tools.
• An extendable, object-oriented engine written in C++. This architecture can loading commands and resources both statically and dynamically. Easy for porting and debugging.
• Takes Python as scripting language. Automatically provides support for dynamic data type. Easy for development and cooperating with C++ host.
