Abstract

La invención se refiere a un método para generar una función de textura bidireccional (BTF) de un objeto, comprendiendo el método al menos las siguientes etapas: - medir una BTF inicial (103) para el objeto utilizando un dispositivo de medición con cámara, - capturar los datos de reflectancia espectral (105) para el objeto para un número predeterminado de geometrías de medición diferentes mediante un espectrofotómetro, - adaptar la BTF inicial (103) a los datos de reflectancia espectral capturados (105), obteniendo así una BTF optimizada (107). La invención se refiere además a sistemas respectivos para generar una función de textura bidireccional de un objeto. (Figura 1).
