Fuzzy geometric modeling provides a useful tool to introduce uncertainty into mathematical spline model. In this paper a new concept of a geometric modeling is presented, based on the theory of fuzzy numbers. By the notion of fuzzy number we introduce fuzzy control point for fuzzy curve and fuzzy surface model for CAGD.

Proceedings of the ACM Symposium on Virtual Reality Software and Technology - VRST '96, 1996
Virtual environments open up new opportunities and challenges for geometric modeling systems. A general approach to geometric modeling suitable for the Cave Automatic Virtual Environment is described. The approach is based on alpha complexes, and some of its capabilities are demonstrated by applying it to the study of biomolecules.

Texture mapping has become an essential tool in any synthetic rendering scheme that aims at photorealism. Texture mapping typically associates any point on the surface of the rendered object with a location in the texture space. The surface point is then assigned rendering attributes, such as color or translucency from the respective location found in ...

This paper presents an experiment that demonstrates the feasibility of successfully applying CASL to design 3D geometric modelling software. It presents an abstract specification of a 3D geometric model, its basic constructive primitives together with the definition of the rounding high-level operation.

GEOMETRIC MODELLING AND ROBOTICS
International Journal of Shape Modeling, 2000Robots and machine tools are physical devices whose acceptable actions depend critically on the shape of their environments, yet traditionally there has been little research that looks specifically at the best way to combine geometric modelling and robotics.

Decision trees for geometric models
Proceedings of the ninth annual symposium on Computational geometry - SCG '93, 1993A fundamental problem in model-based computer vision is that of identifying which of a given set of geometric models is present in an image. Considering a "probe" to be an oracle that tells us whether or not a model is present at a given point, we study the problem of computing efficient strategies ("decision trees") for probing an image, with the ...

Geometrical illusions: study and modelling
Biological Cybernetics, 1997The phenomena of geometrical illusions of extent suggest that the metric of a perceived field is different from the metric of a physical stimulus. The present study investigated the Müller-Lyer and Oppel-Kundt illusions as functions of spatial parameters of the figures, and constructed a neurophysiological model. The main idea of the modelling is based

Geometric models with weigthed topology
Computers & Graphics, 2011This paper introduces the concept of weighted topology to model a 3D object whose connectivity and metric depend on a novel notion of weighted arc-length. The weighted arc-length between any two points of the shape takes into account the fact that a part of the object may be either weakly or strongly connected to another part.
