Following a well-received presentation at 3DV by Zihan, the team took home a Best Paper Honourable Mention award for their efforts, a recognition that caught both authors by surprise and one that came at the end of a long road that began with rejections from SIGGRAPH and SIGGRAPH Asia last year. “Most of the reviews were nice, but they didn’t think SLAM was suitable for the SIGGRAPH community,” Zihan reveals. What do they think the judges at 3DV saw in the work? “If I try to think about why we got this award, I’d say it’s because we have good visualizations,” Songyou asserts confidently. “We show really good results in novel view synthesis and surface rendering and decent results on tracking as well. Also, we provide a solution for a challenging task. It might not be the fastest, but we provide a clue that it’s possible.” Best Paper 3DV Hon. Mention
