This dissertation is about the study of crowd simulation and why the crowd simulation is in need in the movies. Particularly concentrating about the computer generated movies simulating a large crowd is the most difficult task in the production pipeline. So finding a better way to give the audience the feel of crowd is the challenge. Researching about the silhouettes and its uses will help to implement the silhouette to establish the crowd. Silhouettes helps in many ways to create a mystic mood. . As implementing silhouette in the crowd simulation will helps to reduce the secondary animation and facial expression. As there are so many softwares exist to helps the crowd simulation, This paper will focus on a procedure which will create a crowd simulation by transferring the animation from one character to another character in a simpler and easier way.
Chapter 1: Introduction
Animation gives the life to the character. Animating a particular character takes a long time to give the feel. This dissertation is about researching the animation, animating the entire crowd is the difficult task in the animation pipeline. So this dissertation is mainly carried out to find a way to transfer the animation from one character to another character in a simpler and easier way.
Crowd simulation is a process of simulating a group of members, objects or characters. When simulating a large number of characters in a live feature film is not a big deal. Man power is more important in simulating a crowd in feature film. Particularly concentrating on the computer generated movies, replicating the characters animation and behavior from one character to many character is a big deal. A lot of research is done about the crowds and the formation of crowds in society. For example, social gatherings, meetings, assemblies, religious ceremonies and sport events.
The main aim of the project is to achieve an essential method for crowd simulation for animation.
1.2| Research question:
The research question for this study will be.
- What is crowd simulation?
- Why we need crowd simulation?
- Researching the existing crowd simulation method.
- Disadvantages of existing crowd simulation method.
- How silhouette helpful for the animation poses?
- How silhouette will be useful for simulating a crowd?
1.3| Statement of problem:
Animating the entire crowd is the most biggest problem. Technically, creating the crowd is not a big deal but at that same time transferring the animation to each and every character with the different timing is the big deal. The another problem is that the rendering the whole scene with lots and lots of character in a particular scene will make the scene the most complicated one. So finding a better solution for creating the entire scene in Maya with lots and lots of character which has the different timing in their animation. There are several methods for the development of crowd simulation. The major method is using Maya’s Dynamics. There are several external softwares which helps to simulate a entire crowd. But the method which said by this dissertation is quite simple and easier than comparing to another external softwares and Maya’s Dynamics.
- Various types of crowd simulation method.
- Silhouette/ Various types.
- To study the golden poses for animations.
- Explore the secondary motion for animation.
- New methods of producing crowd simulation.
1.5| Significance of study:
Most of the computer generated movies currently released like Madagascar, Horton hears a Who, had a clear idea about the crowd simulation. The focus of the study in this dissertation is about the simulation of crowd in a simpler and easier way and developing a simple procedure for transferring animation from one character to multiple characters.
This study is carried out for developing a better technique for crowd simulation in future upcoming CG projects.
The hypothesis of this dissertation is an animator can easily transfer the animation from one character to multiple character for simulating a crowd and also using the silhouette to visualize the crowd shot with a different perspective.

Chapter 4:Crowd Simulation
A crowd is defined to be collection of people or group of people. The term crowd is mainly referred to the collection of humans as well as animals. Crowds in also defined as the sharing of emotional experience. A crowd can be named by the purpose or different types emotions, such as riot, social gatherings, meetings, assemblies, religious ceremonies, general meetings and sport events.
Scholars differ about what classes of social events fall under the rubric of collective behavior. In fact, the only class of events which all authors include is crowds. Clark McPhail, who treat crowds and collectives as synonyms. His important contribution is to gone beyond the others to carry out empirical studies of crowds. He finds them to form an set of types.
The treatment of crowds is Gustave LeBon, The Crowd: A Study of the Popular Mind (1896), in which the author, a frightened aristocrat, interpreted the crowds of the French Revolution as irrational reversions to animal emotion, and inferred from this that such reversion is characteristic of crowds in general. Freud expressed a similar view in Group Psychology and the Analysis of the Ego (1922). Authors thought that their ideas were confirmed by various kinds of crowds, one of these are the virtual economic. In Holland, during the tulip mania (1637), the prices of tulip bulbs rose to astronomical heights. An array of such quotes was quoted by the authors from the different part of the world. Mainly and other historical odds is said by Charles MacKay’s Popular Delusions and the Madness of Crowds (1841).
At the University of Chicago, Robert Park and Herbert Blumer approved with the speculations of LeBon and other that crowds are formed by emotional. But a crowd is capable of any emotion, not only the negative ones of anger and fear.
A number of authors modify the common-sense of the crowd to include episodes during which the participants are not assembled in one place but are dispersed over a large area. Turner and Killian refer to such crowds, examples being Billy Graham’s, their expanded definition of the crowd is justified if propositions are compact crowds do so for diffuse crowds as well.
Some psychologists have proved that there are three fundamental human emotions: fear, joy, and anger. Neil Smelser, John Lofland, and others have proposed three corresponding forms of the crowd: the panic (an expression of fear), the craze (an expression of joy), and the hostile outburst (an expression of anger). Each of the three emotions can characterize either a compact or a diffuse crowd, the result being a scheme of six types of crowds. Lofland has offered the most explicit discussion of these types.
4.3| Types of Natural crowd:
There are already many types of crowd in the society, mainly they are classified into businesses and projects based crowd formation. But when we study about crowd sourcing and the crowds that influence it, we always like to the talking about one big crowd, one only crowd type that can fulfill every task.
Well that’s not what happens in reality, and Author Nicholas Carr had a interesting blog post which states about this and his mind thoughts over the typology of crowds, after studying about the crowd sourcing we can find a piece for the PBS Digital Nation site.
He suggests the following 4 types of crowds in crowd sourcing:
– Social production crowd: consists of a large group of individuals who lend their individual talents to the devolved creations like Wikipedia or Linux.’
This one basically fits in the most examples of crowd sourcing.
– Averaging crowd: classifies exactly as a survey group, giving an average judgment about some complex matter in some cases, is more accurate than the judgment of any one individual person in the society.’
Nicholas Carr defines that prediction markets are a typical examples of this different types of crowd, or even the stock market for that matter.
– Data mine crowd: A large group that, the basic common knowledge and understanding of all its members who produces a collection of behavioral data or information that can be collected verified by the authors from various country put under a series of examine in order to gain insight into behavioral or market patterns.’
The example are defined here is the crowd that are mainly feed Google’s search engine and Amazon’s search engine. So here we all are involving ourselves in this crowd sourcing effort without knowing that we’re particularly helping the system.
– Networking crowd: a group that exports and import information through a shared communication system such as the phone network or Internet service. Internet service are mainly concentrated on the social networking like Orkut, hi 5, Facebook or Twitter.’
Here we’re not aware about being members of information collection, and if not handled carefully by the companies, could put a backfire on this type of services.
After these 4 types, two were suggested. One by Clay Shirky, who was also, involved in this discussion, and another one from a suggestion by a commenter on the blog, Tom Lord. That’s crowd sourcing working right there!
– Transactional crowd: a group used to coordinate what are mainly point-to-point transactions, such as the type of crowd collected by eBay, Match.com, Innocentive, LinkedIn and similar services.’
– Event crowd: A group organized through online communication for a particular event, which can take place either online or in the real world and may have a political, social, aesthetic, or other purpose.’
