Ringing subdivision of curves and surfaces (2009)
Jarek Rossignac, Abhishek Venkatesh
Split&Tweak subdivisions iteratively refine a polygon by inserting a vertex in the middle of each edge (Split) and then moving each vertex to an affine combination of five consecutive vertices...
Coherent object selection in pattern hierarchies (2009)
We present an approach for encoding and specifying coherent selections in pattern hierarchies. Hierarchies of patterns of features or other modeling entities are used in architectural and mechanical...
Parabola-Based Discrete Curvature Estimation † (2009)
Hyoungseok Kim, Jarek Rossignac
The local geometric properties such as curvatures and normal vectors play important roles in analyzing the local shape of objects. The result of the geometric operations such as mesh simplification...
OCTOR: OCcurrence selecTOR in pattern hierarchies (2009)
Hierarchies of patterns of features, of sub-assemblies, or of CSG sub-expressions are used in architectural and mechanical CAD to eliminate laborious repetitions from the design process. Yet, often...

Lengyel) contains 400 frames of the same connectivity, each having 41 components with a total of 5664 triangles and 3030 vertices. Dynapack quantizes the floating point coordinates of the vertices to...
Squeeze: Fast and Progressive Decompression of Triangle Meshes (2000)
Renato Pajarola, Jarek Rossignac
An ideal triangle mesh compression technology would simultaneously support the following three objectives: (1) progressive refinements of the received mesh during decompression, (2) nearly optimal...
