“…Situations involving hostilities using resources such as stones and tear gas cannisters are modeled in CrowdMAGS (Moulin & Larochelle, 2010). While having a character possess various resources (its "inventory") is common in games and simulations, the portrayal of these items on a realistic body model is best exemplified by the approach to accessories in Maïm, Yersin, & Thalmann (2009). Accessories can range from small detail items such as watches or glasses to clothing options such as hats, or even to larger goods such as backpacks.…”

The Distribution of Carried Items in Urban Environments

Virtual heritage architectural and cultural reconstructions may be enhanced by populating the environment with simulated people. There are a number of important human modeling issues to address such as situationally-appropriate clothing, occupations, and behaviors. Our interest here is focused on how people interact with portable items in their environment: namely, whether they are carrying items and what those items are. With an end goal of enabling lifelike, data-driven agent-based populace simulations, we conducted an informal but systematic ethnographic observational study of the items carried by more than 3,000 people in two different urban community environments: an indoor market and an outdoor city plaza. We recorded the number and types of items carried by each person, along with their gender, estimated age category, and whether they were alone or in a group. We performed a basic statistical analysis of the results. There were two highly significant findings: (1) a strong and similar majority of all people carry at least one item (76.63% in the indoor setting and 79.79% in the outdoor setting); and (2) the types and amounts of items carried were highly consistent across the two different environments, implying that the data may be applicable in a wide range of scenarios.

“…Our interest was piqued by the unknown distribution of carried items in a "typical" urban setting. If we could obtain such data, existing computer animation techniques such as those in Maïm, Yersin, & Thalmann (2009), Bogdanovych et al (2010), or Liu, Hertzmann, & Popović (2005 could be exploited for crowd simulation realism.…”

“…This work was extended by [1] to generate the whole body of an avatar. A different approach was taken by [12] and [18] who used variance of attachments and textures over a predefined set of avatars, where avatars mainly differed in size and the type of textures, while still appearing as clones that undergone a minor modification.…”

Simulating large crowds of virtual agents has become an important problem in virtual reality applications, video games, cinematography and training simulators. In this paper, we show how to achieve a high degree of appearance variation among individual 3D avatars in generated crowds through the use of genetic algorithms, while also manifesting unique characteristic features of a given population group. We show how virtual cities can be populated with diverse crowds of virtual agents that preserve their ethnic features, illustrate how our approach can be used to simulate full body avatar appearance, present a case study and analyze our results.

“…For each instance, one texture is randomly chosen within the template's available set. Then, color and shape variety techniques are applied, so that instances of a same template and using the same texture are still different [1]. To generate many locomotion animations for each human template, we use a motion-capture-based locomotion engine [2,3].…”
