WALLERN, AUSTRIA — The popular T-Rex Café at Disney Springs, formerly Downtown Disney Marketplace, at Lake Buena Vista, FL, is a monster-sized, Palaeozoic-themed restaurant that bills itself as a Prehistoric Family Adventure. In addition to serving Caveman Punch and Raptor Rita cocktails, the menu includes such Paleo-themed delicacies as Mastadon Stuffed Chicken and Tar Pit Fried Shrimp for adults, while the offerings for junior archaeological expeditioners include Paleo Pizza and Sabre-tooth Sundaes.
The theming is extensive and spectacular, and certainly includes enough pre-historic atmosphere to stir the imaginations of dinosaur enthusiasts of all ages. Highlights include a vast and impressive ‘crystal cave’ that constantly sweeps through a range of intense backlit colors and thickets of cretaceous jungle foliage around smoke-emitting tar pits. All of this provides a backdrop for the stars of the show, the cast of 23 fully-articulated animatronic prehistoric creatures that include such usual dinosaur suspects as tyrannosaurus rex, apatosaurus, triceratops, mastodons, and a woolly mammoth family, together with pteronodons and an 11-meter giant octopus suspended over the bar and the heads of the diners.
A star ceiling and suspended models of the planets provide an outdoor night time atmosphere to a large section of the dining area. Several times an hour this tranquil night sky is disturbed by a massive meteor shower which agitates the animatronic beasts who are further terrified when a massive asteroid crosses the sky and smashes into the earth, shaking the building with 8kW of sub-bass rumbles and crashes. Cinematic quality HD video content for the meteor shower was created by AVHD Visual Solutions, Canada. This is the famous Cretaceous–Paleogene event, which is thought to have brought on the extinction of the dinosaurs and the rise of us mammals.
Although the entire attraction has been running successfully and reliably for many years, some improvements were needed. “In particular, the five 4K-lumen projectors blended to deliver the meteor and asteroid show, together with a single projector in the retail area, needed occasional replacement lamps and realignment of overhead projector blends after each re-lamping,” said Kevin Zevchik, US Manager at AV Stumpfl Inc (www.avstumpfl.com).
High-tech experience
AV Stumpfl and local integrator Zanim8tion came up with a powerful solution for the lamp issue and an ingenious one for the projector alignment, bringing the T-Rex Café from prehistoric AV to the brink of what’s possible today.
First, the five aging projectors were replaced with just two of Digital Projection’s 11K ANSI lumen, laser-powered HIGHlite WUXGA projectors with an operational life of 20,000 hours before requiring re-lamping. Based on their current usage cycle of a two-minute show every 20 minutes, the projectors are estimated to be able run for about 56 years before the lasers will need replacing.
Despite their effectively-infinite lamp life, the projectors will still require regular maintenance visits to clean the optics and change the dust filters, which will inevitably have some impact on their alignment. This where the café’s new AV Stumpfl Wings VIOSO system that controls the projector blends and media replay comes into its own. “Once the maintenance crew has finished handling the projectors, Wings VIOSO uses a small, dedicated camera pointed at the ceiling to automatically realign the images and the blends, and have the show ready within five minutes of completing projector maintenance. Nobody is going to miss the tedium of projector alignment,” enthuses Zevchik.
The other big step forward in the upgrade was to replace the faithful early-model AV Stumpfl SC-Master show controller with a system that would allow the programming of custom dinosaur shows for such occasions as corporate events and educational tours that areplanned to extend the range of activities for the T-Rex Café. In addition tothe audio, video and projection elements controlled by the new Wings Engine, the new AV Stumpfl AVIO network has 12 Wings IObox relay controllers taskedwith running the 192 movement controllers that drive the animatronic models.
The flexibility and ease of programming of the Wings AVIO system has allowed the development of new movement sequences and the independent programming of individual dinosaurs for the educational tours. By taking advantage of the new Wings Touch user interface system the entire replay system can now be controlled from simpletablet devices when staff need to conduct tours or customize the entire venue for specific events and applications.
