Juan Raúl Padrón Griffe

Epale! I am a Marie Sklodowska-Curie fellow of the EU Project PRIME and a PhD candidate at the Graphics and Imaging Lab (Universidad de Zaragoza). My PhD thesis under the supervision of Prof. Adolfo Muñoz and Adrian Jarabo focuses on developing theory and methods for accurate and efficient rendering of complex volumetric appearances. Previously, I obtained my Bachelor degree in Computer Science (2015) at the Central University of Venezuela. Later, I received my Master degree in Informatics (2020) at the Technical University of Munich. During my Master studies I focused mostly on the Computer Graphics and Vision subjects, where I was fortunate enough to be advised by Prof. Matthias Niessner and Dr. Justus Thies at the Visual Computing lab to conduct my research on 3D Scanning and Neural Rendering. I am currently looking for a postdoctoral position.

I am a computer scientist enthusiastic about the intersection of realistic image synthesis, graphics-based vision and machine learning for the digital acquisition, representation and understanding of the visual world. I am currently interested in pushing the state of the art on physically-based rendering of complex multi-scale materials like biological tissues. In my research, I rely on powerful tools like Monte Carlo simulation and gradient-based optimization. In the long term, I believe the combination of powerful forward models (simulation algorithms) and inverse models (gradient-based models) could be impactful in other interesting domains too like computational biology.

Collaborative Augmented Reality on Interactive Surfaces

2019, Oct 12    

Nowadays, the conceptual design process of early architectural ideas has gained significant attraction. Technology plays an essential role in making this process more intuitive and efficient. Based on this premise, the Collaborative Design Platform was developed at the Technical University of Munich as an interdisciplinary research project between the Augmented Reality and Architectural Informatics chairs.

We strongly believe that current Augmented Reality technologies can improve significantly the user experience on the early design process stages. Augmented Reality has the power to visualize any data that we want in the real world. In particular, Microsoft HoloLens seems to be a good candidate. Therefore, the main goal of my Interdisciplinary Project is the integration of Microsoft HoloLens devices to the CDP platform using the HoloToolkit in Unity. This mean that users can see and interact with the virtual scene directly on top of the projection surface.

For the Performance Based Design project, we develop a plugin in Rhino to help architects with the task Aufstockung, i.e., raising an existing building by one or more floors. This plugin can compute the maximum building volume and the optimal numbers of bulding modules based on the legal and physical restrictions provided by the user such as maximum height or GFZ. In addition, we consider the adaptation to the staircases.

Results:

Instructors: Chloe Eghtebas, Gerhard Schubert
Team Members: Juan Raul Padron Griffe, Ines Nopper, Hannah Winklmann

Most of the work was done by Innes Nopper and Hannah Winklmann, so I really encourage you to check their profiles if you are interested in these topics.
