Fraunhofer IGD invites you to a networking event where guests can discuss these technologies and their applications with our experts. The reception will take place on August 15, 2018 at the Steamwork Restaurant, not far from the Vancouver Exhibition Center. From 7 pm to 11 pm you will have the opportunity to learn about these researchers and their projects firsthand. Additional demos will also be presented on the subject of simulation in connection with 3D printing and the 3D visualization software Instant3Dhub, which displays scalable 3D objects on all end devices, even in augmented reality.

Fraunhofer IGD invites you to a reception for SIGGRAPH 2018. In the rustic atmosphere of a brewery, Max Limper and Philipp Urban will present their papers, which have been acclaimed by ACM SIGGRAPH. Refreshments will be served.

Box Cutter: Atlas Refinement for Efficient Packing via Void Elimination

Paper

Abstract

Fresh from his doctorate, this is not Max Limper’s first trip to Canada: In co-operation with the two scientists Nicholas Vining and Alla Sheffer from the University of British Columbia UBC, he presents the paper Box Cutter: Atlas Refinement for Efficient Packing via Void Elimination“. The ‘Box Cutter’ software takes on the textures of 3D objects that are usually stored two-dimensionally on a so-called atlas and subsequently placed on the 3D object during visualization. The algorithm of the software calculates the creation of the texture files more optimally than before, so that empty spots on the atlas are detected and removed. The more efficient use of pixels leads to better quality with the same data volume.

3D Printing Spatially Varying Color and Translucency

Abstract

The paper “3D Printing Spatially Varying Color and Translucency,” describes the latest ways to make 3D printing even more realistic. The latest Cuttlefish version developed by Fraunhofer IGD incorporates the technology presented in the paper and supports RGBA textures that include both color and translucency information, ranging from completely opaque to completely transparent. The driver allows users to print multiple overlapping models, each with one or more RGBA textures. 3D models of this kind can be created with standard 3D modeling tools and stored in standard file formats (such as OBJ or WRL). Translucency is necessary to make skin look real and makes it possible, for example, to print a human figure with opaque clothing and completely transparent glasses in a single printing process. But the technology is also interesting for prototypes in medical education: Parts of the human body can be printed transparently to clearly explain surgical procedures to young physicians.
