      Modeling objects, their properties and relations is an important topic in computer science. In this sense, this research contributes to the framework of heterogeneous solid modeling, as well as the popular and intricate study of implicit solid representation. The approach presented here is broad and generic, but this article will focus on bio-CAD models, alluding to the existing extension and implementation in other fields. The overall aim of this work is to demonstrate that solid models of heterogeneous object can be built implicitly. This is shown to have promise in practical applications from biomedical computing to computer animation and engineering. The approach adopted here is based on the observation that current solid models cannot intrinsically represent multiphase geometric information along with the attribute information. This makes necessary to explore new modeling techniques in order to represent real-world objects. The availability of such modeling techniques remains central to the design, analysis, and fabrication of heterogeneous objects ; El modelado de objetos, sus propiedades y relaciones es un tema importante en las ciencias de la computación y la informática. En ese sentido, esta investigación busca contribuir al modelado de objetos sólidos heterogéneos, así como al complejo estudio de la representación implícita de objetos sólidos. El enfoque que aquí se presenta es amplio y genérico, pero este artículo se centra en modelos bio-CAD, aludiendo su extensión y aplicación a otros campos. El objetivo general de este trabajo es demostrar que los modelos geométricos de objetos heterogéneos se pueden representar de forma implícita. Esto promete tener gran variedad de aplicaciones prácticas desde la computación biomédica hasta la animación por computador y la ingeniería aplicada. El enfoque adoptado aquí se basa en la observación de que los modelos sólidos actuales no pueden representar intrínsecamente información geométrica multifase junto con la información de los atributos. Esto hace necesario ...
