There are many applications of computer animation and simulation where it is necessary to model virtual crowds of autonomous agents. Some of these applications include site planning, education, entertainment, training, and human factors analysis for building evacuation. Other applications include simulations of scenarios where masses of people gather, flow, and disperse, such as transportation centers, sporting events, and concerts. Most crowd simulations include only basic locomotive behaviors possibly coupled with a few stochastic actions. Our goal in this survey is to establish a baseline of techniques and requirements for simulating large-scale virtual human populations. Sometimes, these populations might be mutually engaged in a common activity such as evacuation from a building or area; other times they may be going about their individual and personal agenda of work, play, leisure, travel, or spectator. Computational methods to model one set of requirements may not mesh well with good approaches to another. By including both crowd and individual goals and constraints into a comprehensive computational model, we expect to simulate the visual texture and contextual behaviors of groups of seemingly sentient beings.

This volume presents novel computational models for representing digital humans and their interactions with other virtual characters and meaningful environments. In this context, we describe efficient algorithms to animate, control, and author human-like agents having their own set of unique capabilities, personalities, and desires. We begin with the lowest level of footstep determination to steer agents in collision-free paths. Steering choices are controlled by navigation in complex environments, including multi-domain planning with dynamically changing situations. Virtual agents are given perceptual capabilities analogous to those of real people, including sound perception, multi-sense attention, and understanding of environment semantics which affect their behavior choices. The roles and impacts of individual attributes, such as memory and personality are explored. The animation challenges of integrating a number of simultaneous behavior and movement demands on an agent are addressed through an open source software system. Finally, the creation of stories and narratives with groups of agents subject to planning and environmental constraints culminates the presentation.

Research into the methods and techniques used in simulating crowds has developed extensively within the last few years, particularly in the areas of video games and film. Despite recent impressive results when simulating and rendering thousands of individuals, many challenges still exist in this area. The comparison of simulation with reality, the realistic appearance of virtual humans and their behavior, group structure and their motion, and collision avoidance are just some examples of these challenges. For most of the applications of crowds, it is now a requirement to have real-time simulations – which is an additional challenge, particularly when crowds are very large. Crowd Simulation analyses these challenges in depth and suggests many possible solutions. Daniel Thalmann and Soraia Musse share their experiences and expertise in the application of: · Population modeling · Virtual human animation · Behavioral models for crowds · The connection between virtual and real crowds · Path planning and navigation · Visual attention models · Geometric and populated semantic environments · Crowd rendering The second edition presents techniques and methods developed since the authors first covered the simulation of crowds in 2007. Crowd Simulation includes in-depth discussions on the techniques of path planning, including a new hybrid approach between navigation graphs and potential-based methods. The importance of gaze attention – individuals appearing conscious of their environment and of others – is introduced, and a free-of-collision method for crowds is also discussed.

Over the last several years there has been a growing interest in developing computational methodologies for modeling and analyzing movements and behaviors of ‘crowds' of people. This interest spans several scientific areas that includes Computer Vision, Computer Graphics, and Pedestrian Evacuation Dynamics. Despite the fact that these different scientific fields are trying to model the same physical entity (i.e. a crowd of people), research ideas have evolved independently. As a result each discipline has developed techniques and perspectives that are characteristically their own. The goal of this book is to provide the readers a comprehensive map towards the common goal of better analyzing and synthesizing the pedestrian movement in dense, heterogeneous crowds. The book is organized into different parts that consolidate various aspects of research towards this common goal, namely the modeling, simulation, and visual analysis of crowds. Through this book, readers will see the common ideas and vision as well as the different challenges and techniques, that will stimulate novel approaches to fully grasping “crowds."

The digital revolution is interwoven with the promise to empower the user. Yet, the rise of centralized, commercial platforms for crowdsourced work questions the validity of this narrative. In Crowd-Design, Florian Alexander Schmidt analyses the workings and the rhetoric of crowdsourced work platforms by comparing the way they address the masses today with historic notions of the crowd. The utopian concepts of early online collaboration are taken as a vantage point from which to view and critique current and, at times, dystopian applications of crowdsourced work. The study is focused on the crowdsourcing of design tasks, but these specific applications are used to examine the design of the more general mechanisms employed by the platform providers to motivate and control the crowds. Crowd-Design is as much about the crowdsourcing of design as it is about the design of crowdsourcing.

There are many applications of computer animation and simulation where it is necessary to model virtual crowds of autonomous agents. Some of these applications include site planning, education, entertainment, training, and human factors analysis for building evacuation. Other applications include simulations of scenarios where masses of people gather, flow, and disperse, such as transportation centers, sporting events, and concerts. Most crowd simulations include only basic locomotive behaviors possibly coupled with a few stochastic actions. Our goal in this survey is to establish a baseline of techniques and requirements for simulating large-scale virtual human populations. Sometimes, these populations might be mutually engaged in a common activity such as evacuation from a building or area; other times they may be going about their individual and personal agenda of work, play, leisure, travel, or spectator. Computational methods to model one set of requirements may not mesh well with good approaches to another. By including both crowd and individual goals and constraints into a comprehensive computational model, we expect to simulate the visual texture and contextual behaviors of groups of seemingly sentient beings.

Ownership of cryptocurrencies features contrasting forms of mobilization. On one hand, it denotes association with a global crowd of unrelated individual investors, which expands as it attracts more members. On the other hand, it includes participation in grassroots communities, which are generally more insular. Crypto Crowds demonstrates how this tension generates political, economic and moral realities in different cultural and geographical contexts. Pioneering in its approach to cryptocurrency trading, this volume will inspire scholars interested in the sociality of decentralized business models, boom-and-bust cycles on the blockchain, libertarian utopias and other postmodern crowding phenomena.

Crowds and Party channels the energies of the riotous crowds who took to the streets in the past five years into an argument for the political party. Rejecting the emphasis on individuals and multitudes, Jodi Dean argues that we need to rethink the collective subject of politics. When crowds appear in spaces unauthorized by capital and the state-such as in the Occupy movement in New York, London and across the world-they create a gap of possibility. But too many on the Left remain stuck in this beautiful moment of promise-they argue for more of the same, further fragmenting issues and identities, rehearsing the last thirty years of left-wing defeat. In Crowds and Party, Dean argues that previous discussions of the party have missed its affective dimensions, the way it operates as a knot of unconscious processes and binds people together. Dean shows how we can see the party as an organization that can reinvigorate political practice.
