Generación procedural de edificios 3D utilizando los lenguajes VEX/Python (Houdini) a partir de datos georreferenciados por Sistemas de Información Geográfica (SIG)

Abstract

[Resumen] El modelado geométrico de edificios para grandes áreas rurales plantea un importante desafío con aplicación en múltiples ámbitos. Los videojuegos son un ejemplo donde el modelado procedural se utiliza con frecuencia para poblar mundos virtuales. La planificación urbanística y la simulación, son otros dominios donde levantar construcciones sobre el terreno permite presentar simulaciones más realistas. El modelado procedural engloba técnicas dentro de las ciencias de la computación para generar contenidos bajo demanda. En particular, el modelado procedural de geometría permite crear modelos 3-D con una mínima intervención humana o incluso de forma autónoma. En este proyecto, proponemos modelar proceduralmente la geometría exterior de casas y pequeños edificios industriales a partir de un mapa rural dividido en parcelas. El sistema propuesto, construido en Houdini, decidirá qué parcelas pueden ser utilizadas para construir diferentes tipos de edificaciones. Ilustraremos el sistema diseñado con mapas del mundo real obtenidos a partir de bases de datos GIS existentes.

[Abstract] The geometric modeling of buildings covering wide rural areas poses an important challenge with application in multiple domains. Video games are famous examples where procedural modeling is widely adopted to populate virtual worlds. Followed also by urban planning and simulation, where building lands can be built up to present more accurate and realistic simulations. Procedural modeling is a well-known approach in computer science to generate on-demand content. In particular, procedural geometric modeling tackles the problem of creating complex 3-D models with minimal human intervention or completely autonomously. In this project, we propose to tackle the procedural modeling of the external geometric shape of houses and small industrial buildings that is generated from a given rural map divided into plots. The proposed system, built on top of Houdini, will automatically decide which plots can be utilized to build up a variety of houses and buildings with different floor shapes. We illustrate the designed system with real-world maps from existing GIS databases.
