Halo, I’m Ran Zhang!
I'm a fourth-year PhD student and Computational Design Researcher(CoDeR) in Visual Computing Lab at IST Austria, where I work with Prof. Bernd Bickel, supported by MSCA-ITN DISTRO project.
Previously, I got my Master degree from the University of Science and Technology of China(USTC) at 2014, supervised by Prof. Xuejin Chen and Prof. Ligang Liu; and a Bachelor degree from Tianjin University at 2011.
My current research interests include Computational design, Digital Fabrication and Human Computation. Check my recent publications.
GraphiCon is an UGC media focus on computer graphics, it is founded by several graphics researchers. Currently it is hosted on Zhihu and Wechat official account platform.
GAMES stands for Graphics And Mixed Environment Seminar, aims at spreading computer graphics techniques and assisting young graphics researchers.
In our SIGGRAPH 2017 paper: Functionality-aware Retargeting of Mechanisms to 3D Shapes, We present an interactive design system to create functional mechanical objects. Our computational approach allows novice users to retarget an existing mechanical template to a user-specified input shape.
Scissor structures are used to generate deployable objects for space-saving in a variety of applications, from architecture to aerospace science. While deployment from a small, regular shape to a larger one is easy to design, we focus on a more challenging task: designing a planar scissor structure that deploys from a given source shape into a specific target shape. We propose a two-step constructive method to generate a scissor structure from a high-dimensional parameter space. Topology construction of the scissor structure is first performed to approximate the two given shapes, as well as to guarantee the deployment. Then the geometry of the scissor structure is optimized in order to minimize the connection deflections and maximize the shape approximation. With the optimized parameters, the deployment can be simulated by controlling an anchor scissor unit. Physical deployable objects are fabricated according to the designed scissor structures by using 3D printing or manual assembly.
