Procedural modeling historical buildings for serious games

[EN] In this paper we target the goal of obtaining detailed historical virtual buildings, like a castle or a city old town, through a methodology that facilitates their reconstruction. We allow having in a short time an approximation model that is flexible for being explored, analyzed and eventually modified. This is crucial for serious game development pipelines, whose objective is focused not only on accuracy and realism, but also on transmitting a sense of immersion to the player.[ES] En este trabajo apuntamos al objetivo de obtener edificios históricos virtuales con alto nivel de detalle, como por ejemplo un castillo o un barrio de una ciudad antigua, a través de una metodología que facilite su reconstrucción. Las herramientas que proponemos nos permiten obtener rápidamente un modelo aproximado y flexible para ser explorado, analizado o eventualmente modificado. Modelos con estas características son esenciales para el desarrollo en plataformas de juegos serios, cuyo objetivo fundamental se centra no sólo en la precisión y el realismo, sino también en transmitir una sensación de inmersión para el jugador.We would like to thank Adriana Desplans for help with the Carcassonne prototype.
