This allows much more complex level geometry and easier editing.Įach cube-shaped node in the octree represents a renderable volume, or a type of Marching cube, which are referred to as a cube, where each edge of this cube can be lengthened or shortened to deform the cube into a variety of other shapes. An octree, in Sauerbraten, is a cube that can be split into eight smaller cubes those smaller cubes are also octrees, and can be subdivided further. The most recent releases (starting with "CTF Edition") support a precomputed visibility system (PVS) for graphics cards that do not support hardware occlusion.Īn example of a primitive cube subdivisionĬube 2: Sauerbraten uses a 6-directional heightfield (or octree) world model. The original Cube engine's rendering engine assumed that overdraw (where polygons that do not appear in the final scene are occluded via the z-buffer) was more processor-intensive than sending new streams of triangles to the graphics processing every frame, which vastly limited its performance on more modern hardware where memory bandwidth is a greater limiting factor. Lighting is precomputed into lightmaps-image files that correspond to geometry as textures-for efficient batching, with an additional stored directional component, that allows for efficient shader-based lighting effects. įeatures Rendering engine Ĭube 2's rendering engine is designed around modern graphics processing units, which perform best with huge batches of geometry already stored in video memory.

In 2012, Mozilla researcher Alon Zakai created a browser based demo called BananaBread by using Emscripten to port the C++ code to JavaScript and WebGL.Syntensity was a fork of Cube 2 focused on creating online content.Cardboard is fork created for the shooter game Carmine Impact available on Steam.Tomatenquark is a fork of Cube 2 that is available from Steam.It offers better graphics, but has higher system requirements. Tesseract, which features an improved version of the Cube 2 game engine.With version 2.0, it has been ported to the engine of Tesseract. Red Eclipse, a fork of Cube 2 with improvements to the engine featuring a different style of gameplay.Platinum Arts Sandbox forks the Cube 2 engine to create a standalone game creation system.Since the engine code is open-source, a number of forks and derivatives have been based on it, most notably: The game was ported to iOS by FernLightning.
The game shares most of its design goals and philosophy with its predecessor, but uses a new 6-directional heightfield (or octree) world model. Single-player modes feature both episodic gameplay and deathmatches on multiplayer maps with AI bots instead of human opponents.Ĭube 2: Sauerbraten started as a redesign of the original Cube game engine. Players can also engage in online cooperative map editing. The game features multiple modes, such as deathmatch, Capture the Flag, and variations thereof. The aim of the project is not to produce the most features and highest-quality graphics possible, but rather to allow map-editing to be done in real-time within the game, while keeping the engine source code small and elegant.Ĭube 2 features singleplayer and multiplayer, the latter offering LAN, local, and online play. The game media is released under various non-free licenses.

The game engine is free and open-source software, under the zlib License, with commercial support available from the developer's business counterpart, Dot3 Labs. The game features single-player and multiplayer gameplay and contains an in-game level editor.
