Outerra

Outerra is a planetary 3D engine in development by the Slovakian team of Brano Kemen, Laco Hrabcak and Tomas Mihalovic since 2008.^[1][2] The engine renders high-quality terrain, terrain texturing, flora and water flow normal maps using relatively sparse and highly compressed data through fractal processing and calculations.

Features

• Fractal refinement of preexisting terrain data.^[3]
• Support of vector-based data, such as roads.
• Seamless transitioning from outer space to planet surface.
• Chromium browser integration.
• Land vehicle physics and JSBSim flight dynamics model library for aircraft physics.
• Unlimited visibility

Issues

The engine has issues with its OpenGL renderer on computers with ATI graphics cards.^[4]
