Mixed Finite Elements for Variational Surface Modeling
Many problems in geometric modeling can be described using variational formulations that define the smoothness of the shape and its behavior w.r.t. the posed modeling constraints....

Conservation principles and action schemes in the synthesis of geometric concepts
In this paper a theory for the synthesis of geometric concepts is presented. The theory is focused on a constructive process that synthesizes a function in the geometric domain re...

DR. GEO II: Adding Interactivity Planes in Interactive Dynamic Geometry
Interactive geometry environments support the creation and exploitation of interactive geometric sketches. However, such environments are often driven in a rigid manner, following...

Merging and smoothing machining boundaries on cutter location surfaces
In region machining, neighbouring regions may be close together, but disconnected. Boundary curves may also have unwanted geometric artifacts caused by approximation and discretis...

Modeling and Visualization of Cardiovascular Systems
Modeling complex organs, such as the human heart, requires a detailed understanding of the geometric and mechanical properties of that organ. Similarly, the model is only as accur...

A roughness measure for 3D mesh visual masking
3D models are subject to a wide variety of processing operations such as compression, simplification or watermarking, which introduce slight geometric modifications on the shape. ...

Comprehensible rendering of 3-D shapes
We propose a new rendering technique that produces 3-D images with enhanced visual comprehensibility. Shape features can be readily understood if certain geometric properties are ...
