Outerra Engine is a unique 3D engine, a world rendering engine capable to seamlessly render whole planets from space down to the ground level. It can use real world data to render the planets realistically, while it also dynamically refines the data using procedural algorithms to provide high ground-level detail.
The engine provides unlimited visibility obstructed only by the planet's curvature, with details ranging from thousands of kilometers down to centimeters. Real time atmospheric rendering, oceans with shore waves.
It can integrate vector data overlays for roads, and land class modifications. Uses the JSBSim Flight Dynamics Model library for high fidelity simulation of aircraft, and Bullet physics engine for simulation of vehicle physics. Terrain and fractal algorithms maximally utilize the GPU, leaving the CPU resources for simulation.
