The last decade has seen a rise the popularity and achievability of large motion graphic outdoor projections. Mainly conducted by commercial companies due to the expense of hiring equipment these projections have utilised scanning and 3D modelling techniques to enchant and enthral audiences. But as the technologies behind projection comes down in price then it becomes in reach of a wider range ...

In this paper we present a three-dimensional model retrieval system. In our approach, a three-dimensional model is described by three invariant descriptors: a curvature index which consists of a histogram of the principal curvatures of each face of the mesh, a histogram of distances between the faces, and a histogram of the volumes based on each face. This work focuses on extracting these invar...

Interactive mesh editing techniques that preserve discrete differential properties are promising to support the design of mechanical parts such as automobile sheet metal panels. However, existing methods lack the ability to manipulate form-features and hard constraints, which are common in engineering applications. In product design, some regions on a 3D model are often required to precisely pr...

This paper presents an open user modeler called the mirror modeler that pretends to be the student and solves sample questions while the student watches mimicking student errors. This ability when added to an interactive teaching environment seems to greatly facilitate the learning process for two types of mathematical series while raising a serious question about the complexity of the third.
