Lattices HENDRIK
It occurs frequently in algorithmic number theory that a problem has both a discrete and a continuous component. A typical example is the search for a system of integers that satisfies certain inequalities. A problem of this nature can often be successfully approached by means of the algorithmic theory of lattices, a lattice being a discrete subgroup of a Euclidean vector space. This article pr...

Hendrik P. A. Lensch Stanford University, USA Abstract We describe texture generation methods for complex objects. Recently developed 3D scanning devices and high-resolution cameras can capture the complex geometry of an object and yield high-resolution images. However, generating a textured model from this input data is still a difficult problem. This task is divided into three subproblems: pa...
