RVO2 Library C++ was featured in an interview on AIGameDev.com, April 29, 2012.
RVO2 Library C++ appears in an article in Intel Visual Adrenaline Magazine and online at Intel Software Network, April 24, 2012.
RVO2 Library C++ has been licensed for the video game Warhammer 40,000: Space Marine from developer Relic.
From a review of Warhammer 40,000: Space Marine in the Daily Telegraph, September 12, 2011:
"It's worth noting, however, that no matter how many orks are barreling your way (and often there will be a lot) the framerate never takes a hit."
Simulations of multiple agents sharing a common workspace have gained increasing attention recently, for various purposes such as crowd simulation, navigating a team of mobile robots, video games, studying natural flocking behavior, traffic engineering, architecture and design, emergency training simulations, etc.
We present an algorithm for interactive navigation and planning of large numbers of agents in two-dimensional (crowded) environments. At runtime, each agent senses the environment independently and computes a collision-free motion based on the optimal reciprocal collision avoidance (ORCA) formulation. Our algorithm ensures that each agent exhibits no oscillatory behaviors.
RVO2 Library C++ is an implementation of our algorithm. It has a simple API for third-party applications. The user specifies static obstacles, agents, and the preferred velocities of the agents. The simulation is performed step-by-step via a simple call to the library. The simulation is fully accessible and manipulable during runtime. The library exploits multiple processors if they are available using OpenMP for efficient parallelization of the simulation.
RVO2-3D Library C++ is an implementation of our algorithm for applications in three dimensions without static obstacles. A C# implementation of our algorithm by Slan is also available.
