Call for Papers 2nd Geometry Processing Workshop NASAGEM 2013 Computer Graphics International 2013 -- New Advances in Shape Analysis and Geometric Modeling -- June 11th 2013, Leibnizhaus Hannover, Germany The NASAGEM workshop will be held under the umbrella of the Computer Graphics International (CGI) Conference, June 11-14th in Hannover. In 2013 the CGI celebrates its 30th anniversary under the auspices of the minister president of Lower Saxony. Of special interest will be contributions addressing issues related to characterizing and representing complex geometrical data and shapes by using concepts from computational and differential geometry, differential equations and computational topology. All accepted submissions will be electronically published as full-length papers. The best papers will be invited to be published as an extended version in a special issue of Springer Journal The Visual Computer. All submissions will be peer reviewed. Full papers in English containing original and unpublished results are solicited. Topics of Interest * 3D data compression including geometric objects and voxel data, modern wavelet methods * The medial axis, its generalizations and applications * Multiscale and multi resolution geometric modeling and appropriate data structures * Applications of methods from computational geometry (including differential geometry) and computational topology (e.g. Morse theory) on shape analysis and shape modeling * Applications of mathematical methods such as ordinary and partial differential equations on shape analysis and shape modeling * Applications of Laplace spectra for shape characterization and compression * Partial image and shape matching * Methods for analysis of dynamic volumetric and image data, based on geometrical, topological and analytical approaches, generalized to higher-dimensional data. * Visualization of dynamical systems for simulations For further details concerning the workshop and the submission, please see: http://cgi2013.welfenlab.de/workshops.php Important Dates for the NASAGEM 2013 workshop: Paper submission deadline Sunday, 14 April 2013 23:59 (GMT) Notification of paper acceptance Monday, 6 May 2013 Camera-ready papers Monday, 13 May 2013 23:59 (GMT) Program and Workshop Co-Chairs NASAGEM 2013: Franz-Erich Wolter, Leibniz University Hannover, Germany Nicholas M.
