Bezier Crust on Quad Subdivision Surface
(The Eurographics Association, 2013)Subdivision surfaces have been widely used in computer graphics and can be classified into two categories, approximating and interpolatory. Representative approximating schemes are Catmull-Clark (quad) and Loop (triangular). ... -
Ellipsoidal Cube Maps for Accurate Rendering of Planetary-Scale Terrain Data
(The Eurographics Association, 2012)Advances in sensor technology lead to a rapidly growing number of terrain data sets with very high spatial resolution. To allow reliable visual analysis of this data, terrain data for planetary objects needs to be rendered ... -
Incomplete 3D Shape Retrieval via Sparse Dictionary Learning
(The Eurographics Association, 2015)How to deal with missing data is one of the recurring questions in data analysis. The handling of significant missing data is a challenge. In this paper, we are interested in the problem of 3D shape retrieval where the ... -
Non-rigid 3D Shape Retrieval via Sparse Representation
(The Eurographics Association, 2013)Shape descriptor design is an important but challenging problem for non-rigid 3D shape retrieval. Recently, bagof- words based methods are widely used to integrate a model's local shape descriptors into a global histogram. ... -
Projecting Points onto Planar Parametric Curves by Local Biarc Approximation
(The Eurographics Association, 2014)This paper proposes a geometric iteration algorithm for computing point projection and inversion on surfaces based on local biarc approximation. The iteration begins with initial estimation of the projection of the prescribed ...
