A object surface reflectance data modeling method for isotropic opaque materials

In computer graphics research, the acquisition and modeling of 3D information of real object and the property of surface reflectance is the base of realistic rendering. This paper proposes a robust data acquisition method for surface reflectance and 3D geometric information data. Based on the accurate data acquisition and processing of the initial data, this paper implements a novel method to render realistic surface. We use the acquisition of real reflectance data to generate the BRDF sampling values of real object surface. In order to attain parametric BRDF expression, and complete the surface reflectance modeling, we use sampling values to fit Ward model. Finally, surface realistic rendering is achieved and the experiments verify the effectiveness and verisimilitude of this method.
