Abstract

Under Crodws

Animated crowds are effective to increase realism in virtual reality or augmented reality applications. However, rendering crowds requires large computational power.

This paper will present:

1. A technique suitable to render large crowds of characters that takes advantage of existing programmable graphics hardware. Impostors are used for low-detail representation, while pseudo-instancing is used for higher detail. A LOD map is used to select between both representations, based on a customizable threshold.
2. Starting of this technique, I propose an artistic application for subway crowds using entry system of control. In this regard, each people is an agent with independent behaviors programmed in XML. In the screens –lobby-stations or inside the train-, we see animations.
