Item Shape Adaptive Cut Lines(The Eurographics Association, 2016) Colaianni, Matteo; Siegl, Christian; Süßmuth, Jochen; Rott, Franz; Greiner, Günther; A. Medeiros e Sa and N. Pietroni and K. Rodriguez EchavarriaWe present a novel method to express base layer and compression garments directly coupled to a human body geometry. Our system enables the transfer of a previously defined patch configuration from a virtual template avatar to arbitrary input bodies. A complete pipeline for the virtual development of second skin garments is presented. The system's strength is the transparent usage for two important scenarios in the apparel industry. On the one hand grading for a population is presented using body shape statistics without using any measurements and on the other hand an approach for custom garment creation in a madeto- shape fashion is proposed.Item Tight Printable Enclosures and Support Structures for Additive Manufacturing(The Eurographics Association, 2016) Hornus, Samuel; Lefebvre, Sylvain; Dumas, Jérémie; Claux, Frédéric; A. Medeiros e Sa and N. Pietroni and K. Rodriguez EchavarriaAdditive manufacturing is a process by which a three dimensional object is created layer after layer, through selective deposition of material. It often requires the automated generation of auxiliary shapes, to temporarily support the object, to protect its surface, or to carve inner cavities and reduce material usage. In this context, we define a printable enclosure as a minimal volume enclosing a given shape and whose boundary can be printed at the smallest possible thickness while ensuring proper bonding between layers. Such an enclosure is well suited to serve as auxiliary structure for additive manufacturing: it is easy to print and require little material. In this paper, we demonstrate its use on three different applications: enclosing a print within protective walls that are close to the surface; generating large inner cavities whose walls are printable, and finally modeling support structures that provide a dense support to the downward facing surfaces while vanishing as quickly as possible below the supported object. We obtain the shape of an enclosure by considering constraints on its set of slices along horizontal planes. In practice, the set of slices is discrete and the constraints afford for an efficient sweep-like construction algorithm using morphological operations on the slices. We discuss the printability and optimality of the enclosures and their boundary walls.
