Foram medidas funções de distribuição de reflexão bidirecional (BRDFs) de folhas de titânio comercialmente puro com três tipos diferentes de morfologia superficial. Esses BRDFs experimentais foram analisados usando o modelo de reflexão de Phong. As medições topográficas das superfícies dos corpos de prova foram realizadas com o método de ponta. Um modelo explícito de microfacetas baseado em dados topográficos foi proposto. Com a utilização do modelo explícito de microfacetas e da óptica geométrica, os BRDFs calculados foram obtidos e depois comparados com os BRDFs experimentais. Ambos estavam em um bom acordo. Através desta comparação foram discutidos os significados físicos do modelo de reflexão de Phong. Concluímos que com a utilização do modelo explícito de microfacetas será possível calcular o BRDF da superfície dos materiais em condições de iluminação arbitrárias e que esta modelagem será útil para desenvolver novas aparências estéticas de superfícies em indústrias de materiais, computação gráfica, projeto arquitetônico e superfícies.

Abstract: Bidirectional reflection distribution functions (BRDFs) of commercially pure titanium sheets with three different kinds of surface morphology were measured. Those experimental BRDFs were analyzed by using Phong's reflection model. Topographic measurements of the specimens' surfaces were performed with using a stylus-method. An explicit microfacet model based on topographic data was proposed. With using the explicit microfacet model and geometrical optics the calculated BRDFs were obtained and then compared with the experimental BRDFs. Both of them were in a good agreement. Through this comparison physical meanings of Phong's reflection model were discussed. We concluded that with using the explicit microfacet model it will be possible to calculate the BRDF of the materials' surface in arbitrary illumination conditions and that this modeling will be useful to develop new aesthetic surface appearance in material industries, computer graphics, architectural design and surface science.
