Comparative Study of Layered Material Models
(The Eurographics Association, 2019)
The accurate reproduction of layered materials is an important part of physically-based rendering applications. Since no exact analytical model exists for any configuration of layer stacks, available models make approximations. ...
ALTA: A BRDF Analysis Library
(The Eurographics Association, 2014)
In this document, we introduce ALTA, a cross platform generic open-source library for Bidirectional Reflectance Distribution Function (BRDF) analysis. Among others, ALTA permits to estimate BRDF models parameters from ...
Diffraction Prediction in HDR Measurements
(The Eurographics Association, 2017)
Modern imaging techniques have proved to be very efficient to recover a scene with high dynamic range values. However, this high dynamic range can introduce star-burst patterns around highlights arising from the diffraction ...
The Effects of Digital Cameras Optics and Electronics for Material Acquisition
(The Eurographics Association, 2017)
For material acquisition, we use digital cameras and process the pictures. We usually treat the cameras as perfect pinhole cameras, with each pixel providing a point sample of the incoming signal. In this paper, we study ...
