For this STORM seminar, Anahid Ghazanfarpour will present her current research works on Multiple Object Mesh Simplification with Contact Preserving Quadric Error Metric.

Abstract
Quadric Error Metric (QEM) is a local simplification method that produces satisfying results for a single object. However, in case several objects with relationships to each other, such as contact, proximity or alignment, are to be simplified, QEM is no longer enough since these relationships are not considered during the simplification process and might get altered. To preserve the relationships between objects as long as possible, we propose a method that will increase the error associated to an edge collapse in a contact zone, by including the quadrics of a close object’s contact zone’s faces into the computation of this error.
