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). ...
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. ...
A Tracking Approach for the Skeletonization of Tubular Parts of 3D Shapes
(The Eurographics Association, 2013)
In this paper we propose a new simple and efficient method to characterize shapes by segmenting their elongated parts and characterizing them with their centerlines. We call it Tubular Section Tracking, because it consists ...
Level of Detail for Real-Time Volumetric Terrain Rendering
(The Eurographics Association, 2013)
Terrain rendering is an important component of many GIS applications and simulators. Most methods rely on heightmap-based terrain which is simple to acquire and handle, but has limited capabilities for modeling features ...
