Honoring "Big Z" at the Q with a Full Court Show

Video Mapped Tribute Fills the Home of the Cavs. Pictured here, a preview of the show within 20,562-seat Quicken Loans Arena (aka The Q)On March 8, 2014, The Cleveland Cavaliers honored their former center, Zydrunas “Big Z” Ilgauskas, by officially retired his #11 team number. But the Cleveland Cavaliers QTV crew did it with a lot more visual sizzle than just an announcement over the P.A. and I-Mag on the center video display. They teamed up with Think Media and Quince Imaging to produce a large format projection that not only covered the expanse of the court but was mapped to its various parts, transforming the 2D surface and content with 3D movement and effects.

Working in tandem with visuals overhead (for those with less-advantageous seating positions near court level), it transfixed attendees with a dazzling pregame and halftime spectacle. And the content was seen by more than those within the Cavs’ 20,562-capacity Quicken Loans Arena (a.k.a. “The Q”). The visuals were picked up by national media outlets including NBC’s Today Show.

Scott Williams, owner of Quince Imaging, notes that the Ilgauskas tribute in Cleveland wasn’t the first time the company has projected visual content onto a basketball court. “For the past couple of years, we have done similar events like the Cavs pre-game show for the Miami Heat, and DC’s Washington Wizards at the Verizon Center.”

The project required projected imagery to be precisely mapped to court zones and features, all within a total 3,600-by-1,878-pixel space. The arsenal of gear included 16 HD projectors (12 Barco HD20, four Barco HD18) and four Pandoras Box Media Servers media servers running v5.5 software along with the latest version of Warper.

Leading up to the March 8 show, Quince Imaging worked with the Cavs and Quicken Loans Arena to align the 12 20K HD projectors with the dimensions and painted elements on the court surface. Despite a significant amount of preplanning, more than a little tweaking was done onsite to get everything perfectly aligned, notes Eric Gazzillo, media server programmer from Quince Imaging.

He notes that the arena floor is regularly removed, replaced and shifted around to accommodate varying seating configurations for different sports events, and while the physical court is put down with precision — usually within an inch — “the painted aspects are not always laid down accurately to their respective drawings.” Gazzillo adds, however, that new software reduces those needed tweaks to “a small problem.”

For the Cavs event, the ability to load in quickly proved particularly advantageous when pyro flame effect testing forced a delay before crews could get the video gear in place. “We had a luxury of extra rehearsal time due to the quick load in, and the Cavs providing extra time in order for the projections to perform flawlessly. They did!”

The content that brought the court to life was a close collaboration between Quince Imaging and the Cavs’ TV crews.  While Quince Imaging handled the 3D content, such as the imagery creating the illusion of a “falling court” and other animations running throughout the video, the Cavs TV crew provided most of the historical images, video and audio.

Quince Imaging also handled all of the rendering and processing of the video mapping in house. “In total, we had four servers processing and running the projection.” While noting that, “with a high profile and important project like this, running multiple servers is a must,” Williams adds “we never ran into any problems.”
