Efficient Resampling, Compression and Rendering of Metallic and Pearlescent Paint
An interesting class of materials are metallic and pearlescent paints. They pose serious challenges to computer graphics since they have high frequencies in both angular and spatial domain, have a complex, pure stochastic spatial structure and angular dependent color shifts. Hybrid approaches that combine model and image-based representations have proven to faithfully reproduce metallic and pea...
متن کاملRendering Pearlescent Appearance Based On Paint-Composition Modelling
We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across different sublayers, while it can be neglected within each of the sublayers. Based on this assumption, an efficient recursive procedure of assembling the layers is developed, which...
متن کاملMeasurement and editing of metallic car paint BRDF
Recent measurement devices for the Bidirectional Texture Function (BTF) offer high parallel capture of the spatial varying reflectance data for material samples. We present an approach to use measurement data from homogenous materials or materials with stochastical mesostructure to obtain data samples for the fitting of BRDF models like CookTorrance. We applied this approach to measured samples...
متن کاملA Computer Aided Color Appearance Design System for Metallic Car Paint
A computer aided design system for determining the color appearance of metallic automotive coatings has been developed. A sketch based bidirectional reflectance distribution function design interface allows simple concept art to be used to style new metallic car colors. The final design is specified using industrial measurement standards for metallic color appearance, and paint formulations are...
متن کاملSolution of an Inverse Problem in Rendering Metallic and Pearlescent Appearance
Physically based rendering of metallic and pearlescent appearance requires knowledge of the composition of paint or coating. However, sometimes composition is not available, while the Bi-directional Reflectance Distribution Function (BRDF) is measured from an actual sample. Such a situation invokes the inverse problem to find a paint composition from a given BRDF. We solve this problem based on...
