StopThePop: Sorted Gaussian Splatting for View-Consistent Real-time Rendering

Thu, 13 Jun 2024 00:00:00 +0000

StopThePop was by far the most focused paper I have been involved in. From concept to submission, it took us only about month to finish this paper - and it was accepted at Siggraph 2024 :-) The idea was clear: we want to add per-pixel sorting of Gaussians for better view-consistency.

Collaborative Control for Geometry-Conditioned PBR Image Generation

Thu, 08 Feb 2024 00:00:00 +0000

January 2023, with the PhD in my pocket, I joined Unity to work on real-time NeRFs. It sounded like the perfect job - I am a big video game enthusiast and already developed several games with Unity, the task is a perfect fit for me and the team I am joining is awesome. Unfortunately, 2023 was not a good year for Unity, with multiple rounds of lay-offs and cost savings that also included our project. But that also created new opportunities for us. Unity started pushing AI features and we got the chance to get familiar with diffusion models and the current state-of-the-art in asset generation. The pace at which new and better approaches are popping up is unbelievable - and it is hard to keep up with the latest news in that area.

MotionDeltaCNN: Sparse CNN Inference of Frame Differences in Moving Camera Videos with Spherical Buffers and Padded Convolutions

Mon, 02 Oct 2023 00:00:00 +0000

MotionDeltaCNN is a follow-up paper to DeltaCNN and the last of the three research collaborations I did with Meta Reality Labs. This is probably a good time to thank them for the great time, and for enabling me to do this research. Special thanks go to Chengcheng Tang: thanks for all the help, it was a blast!

DeltaCNN: End-to-end CNN inference of sparse frame differences in videos

DeltaCNN was my favorite project during my PhD. It’s the second research collaboration with the great team at Meta Reality Labs, and the topic is a perfect match for my skills and interests.

DONeRF: Towards Real‐Time Rendering of Compact Neural Radiance Fields using Depth Oracle Networks

Wed, 02 Jun 2021 00:00:00 +0000

DoNeRF was quite an interesting journey for me. This entire field was completely new to me, but fortunately, NeRFs were new to everyone at the time we started with this project.

UNOC: Understanding occlusion for embodied presence in virtual reality

Tue, 01 Jun 2021 00:00:00 +0000

UNOC was the first of 3 papers I created in collaboration with Meta Reality Labs. During the course of making this paper, I did a four month internship at Meta Reality Labs in Sausalito. This was one of the best experiences I made in my life - working together with great people in great office, and living in a beautiful apartment at the beach in Tiburon.

spECK: accelerating GPU sparse matrix-matrix multiplication through lightweight analysis

This was my first project as PhD student and also the beginning of my passion for CUDA and performance optimization in general.

Human upper-body inverse kinematics for increased embodiment in consumer-grade virtual reality

Sat, 01 Dec 2018 00:00:00 +0000

As a gaming and tech enthusiast, I had to get my hands on a VR headset. Doing a master thesis in VR was a great way to justify that purchase back in 2017.
