Shape Optimization for Consumer-Level Digital Fabrication, Przemyslaw Musialski
Sprache des Titels:
Traditionally, 3d modelling in computer graphics deals with the geometric and visual aspects of 3d shapes. On the other hand, due to the growing capabilities of personal digital fabrication technology and its spread into offices and homes, 3d models are increasingly entering the physical world. Therefore, the physical properties of 3d models come into focus. For example, 3d-printed models should be able to stand balanced in a desired pose without toppling over, or should posses certain properties, like a specific sound if vibrating or a minimal structural strength if exposed to external forces. It is thus desirable to have methods that allow the user to specify the intended physical properties of an object in addition to its 3d geometry, and which automatically take these properties into account when generating a specification for a 3d printer.
In this talk I will give an introduction to such computational design problems and introduce a methodology for efficient non-linear shape optimization.
