چکیده

We survey some of our recent work on real-time path planning and navigation of multiple autonomous agents in dynamic environments. The driving application of our work are real-time crowd simulation for computer games, virtual environments, and avatar-based online 3D social networks. We also present extensions to these methods for accelerating the overall simulation and for modeling more complex behaviors. Finally, we present some preliminary results from our

Towards Believable Crowds: A Generic Multi-Level Framework for Agent Navigation

Path planning and crowd simulation are important computational tasks in computer games and applications of high social relevance, such as crowd management and safety training. Virtual characters (agents) need to autonomously find a path from their current position to a designated goal position. This is usually solved by running the A* algorithm on a grid or a navigation mesh. However, in many m...

Realistic Crowd Simulation with Density-Based Path Planning

Virtual characters in games and simulations often need to plan visually convincing paths through a crowded environment. This paper describes how crowd density information can be used to guide a large number of characters through a crowded environment. Crowd density information helps characters avoid congested routes that could lead to traffic jams. It also encourages characters to use a wide va...

The Explicit Corridor Map: Using the Medial Axis for Real-Time Path Planning and Crowd Simulation

We describe and demonstrate the Explicit Corridor Map (ECM), a navigation mesh for path planning and crowd simulation in virtual environments. For a bounded 2D environment with polygonal obstacles, the ECM is the medial axis of the free space annotated with nearest-obstacle information. It can be used to compute short and smooth paths for disk-shaped characters of any radius. It is also well-de...

A Motion Constraint Dynamic Path Planning Algorithm for Multi-Agent Simulations

In this paper, we present a novel motion-orientated path planning algorithm fo r real-time navigation of mobile agents. The algorithm works well in dynamical and un-configured environments, and is able to produce a collision-free, time -optimal motion trajectory in order to find a navigation path. In addition to the motion constraint path planning, our approach can deal with the unknown obstacl...

A GPU-Based Multi-agent System for Real-Time Simulations

The huge number of cores existing in current Graphics Processor Units (GPUs) provides these devices with computing capabilities that can be exploited by distributed applications. In particular, these capabilites have been used in crowd simulations for enhancing the crowd rendering, and even for simulating continuum crowds. However, GPUs have not been used for simulating large crowds of complex ...
