— Rendering a stiff virtual wall remains a core challenge in the field of haptics. A passivity study of this problem is presented, which relates the maximum achievable wall stif...
Abstract. This paper presents a method for automatic removal of artifacts that appear in silhouettes extracted from polygonal meshes due to the discrete nature of meshes and numeri...

The computation of curvature and other differential properties of surfaces is essential for many techniques in analysis and rendering. We present a finite-differences approach for...
The structure of the image synthesis process naturally leads to the use of object-oriented software design and many existing rendering systems are based on some kind of object-orie...
This paper gives an overview of works done in our group on 3D and appearance modeling of objects, from images. The backbone of our approach is to use what we consider as the princi...
