A Survey of Inverse Rendering Problems
(Blackwell Publishing, Inc and Eurographics Association, 2003)
Inverse rendering problems usually represent extremely complex and costly processes, but their importance in many research areas is well known. In particular, they are of extreme importance in lighting engineering, where ...
BRDF Measurement Modelling using Wavelets for Efficient Path Tracing
(Blackwell Publishing, Inc and Eurographics Association, 2003)
Physically based rendering needs numerical models from real measurements, or analytical models from material definitions, of the Bidirectional Reflectance Distribution Function (BRDF). However, measured BRDF data sets are ...
Soft Object Modelling with Generalised ChainMail - Extending the Boundaries of Web-based Graphics
(Blackwell Publishing, Inc and Eurographics Association, 2003)
Soft object modelling is crucial in providing realistic simulation of many surgical procedures. High accuracy is achievable using the Finite Element Method (FEM), but significant computational power is required. We are ...
Ray Tracing Surfaces with Contours
(Blackwell Publishing, Inc and Eurographics Association, 2003)
We present two algorithms for ray tracing surfaces with contour lines that are level surfaces of scalar fields.
One algorithm renders the contours as bands of constant finite width, while the other renders them as one ...
Automatic View Selection Using Viewpoint Entropy and its Application to Image-Based Modelling
(Blackwell Publishing, Inc and Eurographics Association, 2003)
In the last decade a new family of methods, namely Image-Based Rendering, has appeared. These techniques rely on the use of precomputed images to totally or partially substitute the geometric representation of the scene. ...
