A fragile watermarking scheme for 3D meshes
In this paper, we propose a new fragile watermarking scheme for 3D meshes. Firstly, the watermark information is adaptively embedded into the mesh geometry by slightly adjusting t...

Curvature Vector Flow to Assure Convergent Deformable Models for Shape Modelling
Poor convergence to concave shapes is a main limitation of snakes as a standard segmentation and shape modelling technique. The gradient of the external energy of the snake represe...

Simple Traversal of a Subdivision Without Extra Storage
In this paper we show how to traverse a subdivision and to report all cells, edges and vertices, without making use of mark bits in the structure or a stack. We do this by perform...

Stochastic Billboard Clouds for Interactive Foliage Rendering
We render tree foliage levels of detail (LODs) using a new adaptation of billboard clouds. Our contributions are a simple and efficient billboard cloud creation algorithm designed...

Polygonal Surface Advection applied to Strange Attractors
Strange attractors of 3D vector field flows sometimes have a fractal geometric structure in one dimension, and smooth surface behavior in the other two. General flow visualization...
