Epale! I am PhD candidate at the University of Zaragoza as a member of the PRIME Network with the Graphics and Imaging Lab. My PhD thesis focus on developing theory and methods for efficient rendering of volumetric heterogeneous appearances and it is being supervised by Prof. Adrian Jarabo. 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 research on 3D Scanning and Neural Rendering.

I am really 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. In particular, I am interested on pushing the state of the art on physically-based rendering, neural rendering and inverse rendering. I also find really interesting other research areas from the Graphics and Imaging Lab such as Human Perception and Transient Imaging.

RGB-D Reconstruction for Mixed Reality

2019, Feb 05    

For the 3D Scanning and Motion project at the Technical University of Munich, we propose a real-time marker-less tracking and 3D reconstruction implementation and show how it can be used to create a mixed reality game using the Unity3D game engine. The concept was inspired by the spatial mapping technology behind Microsoft HoloLens and our 3D reconstruction pipeline is based on the Kinect Fusion pipeline. Tracking and reconstruction is performed in real-time using GPGPU acceleration (Cuda 10, DirectX 11 compute shaders). Finally, several Unity modules (e.g. physics, particle systems, etc) can be used to create interesting mixed reality projects.
