Resumen
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.
