Combustion engine is a 3D Game engine written primarily in C++20 and making use of the OpenGL graphics library and the Bullet Physics engine. The project was started in 2012 to create an engine to run a game which never came to be. It is now being used for my current RPG project: A Short Odyssey

Features of the renderer include:

• Physically Based Rendering pipeline with image based lighting
• Screen Space & Planar Reflections
• Soft Shadows with Cascaded Shadow Maps
• Particle effects (Smoke, Fire, Blood, etc.)
• Screen Space Ambient Occlusion (HBAO & SSAO)
• Bloom/Glow
• Parallax Occlusion Bump Mapping
• Heightmapped landscapes with continuous level of detail & horizon Occlusion Culling

Other Engine feature include:

• Bullet Physics Engine integration
• 3D positional audio (using SoLoud)
• Full scripting support (using AngelScript)
• A custom SSE accelerated linear math library
• Cross platform support (Runs on windows and Linux)
