Simulação gráfica em tempo real de lesões dinâmicas em personagens digitais animados

Abstract

Many modern games seek graphics close to reality to engage their players. Although the simulation of some aspects such as the lighting of scenarios is very close to reality, other parts, generally more interactive, are not yet. For example, action, shooting, and horror games use visual effects of injuries such as blood loss, dismemberment, and projectile pe- netration to maintain realism and immersion. However, typically, such effects require too much artistic effort and their interactivity is limited due to their static nature. This work pro- poses a new methodology for creating such effects, mapping character components such as skin, clothes, organs, blood, and bones into interconnected discrete particles, physically simulated in real-time and subjected to fracture algorithms. More specifically, this work proposes an approach to the injury problem and demonstrates its potential by modeling dynamic injuries caused by cuts in arbitrary planes. The results demonstrate that the cuts generated by planes are useful for modeling different dynamic injuries, which are more interactive and require less artistic effort than traditional ones. In addition, this research studies the advantages and disadvantages of the components and algorithms chosen for the solution’s development, showing the potential of physically modeling the characters, but recognizing the limitation. Thus highlighting the next steps necessary to develop other ty- pes of injuries and increase the proposal’s realism.
