In the 1990s, both parents and kids went to see movies such as Titanic, Men in Black, and Jurassic Park. Here was ai l.c o content that appealed to audience members both young and old alike. What made these effects-driven films more appealing was the computer’s ability to create photorealistic creatures and effects that wowed audiences because of their unprecedented believability. In addition, these effects were seamlessly integrated into the films, heightening the experience. gm Unappealing Storytelling The third shift in the animation evolution resulted from what many see as traditional animation’s changing approach in terms of story. The box-office returns in tradieffects-driven movies. In turn, traditional studios tried to broaden their audience through more adult story themes, such as those in Pocahontas, The Prince of Egypt, and The Quest for Camelot. Instead of writing stories that would appeal to the kid in all of Three Major Shifts that Caused the Animation Evolution: • A changed aesthetic of the audience by visual effects-driven movies. • A broadening of the audience for CG through visual effects-driven movies. • Poor stories in traditional animated feature films. ar us, the new screenwriters created stories for adults and hoped kids would like them, too. t@ tional features began to suffer in direct proportion to the rising popularity of visual In addition, traditional features felt that in order to be a success, they had to fol- m low The Lion King formula and be epic in scope. Every studio tried to follow The Lion King mold and make large-scale, epic musicals. Studios were chasing both visual te effects dollars…and The Lion King box-office profits. As animation became a profitable business, stories were overworked by the myriad “creative executives” in their efforts to create a blockbuster. In turn, the traditional movies made after The Lion no King found a smaller audience. Suddenly it seemed that every animated fi lm had to have a giant herd of animals racing down a slope. With improvements in animation came demands for richer backgrounds, more ct complex camera moves, and an ever-increasing level of believability. This increasing to open the door for future characterdriven movies, from Casper to The Lord of the Rings franchise. These movies combine animated characters with live action in what is now one of the staples ta need for more impressive visuals also pushed the budgets of these pictures higher and higher.

In 2003, Disney made the decision to abandon the handdrawn traditional approach for the new, popular CG medium. Today, in light of the Disney/Pixar merger, rumors have begun to surface of the reformation of a 2D unit at the House of Mouse. Looking at the interesting turn of events in animation, many questions come to mind. What makes for a smooth transition? What has helped those who have made the jump? How much of the 2D art form is applicable to the digital realm? What have we gained and lost in the rise of CG? What is the impact of more 2D animators entering the CG industry? Without drawing as a craft threshold, is there room for a new set of animation heroes in CG with a sig- caught many off guard. nature style like, say, Ward Kimball’s (of Disney’s Nine Old Men fame)?

The Image Metrics side of the system analyzes the captured shapes and compares them to measurements of facial movement on more than 200 people, according to Franklin. Then, it extrapolates the muscle groups that created the shapes in the actors’ eyes and mouth. The process works on the principle that any time you gm contract a face muscle, it affects the eyes and mouth. “You can’t contract only one muscle,” says Franklin.

Fluid Simulation m quicker movements so the particle dynamics would work faster and greater, depending on what was needed. ai l.c o “Even though the particle dynamics were used only on 21 shots, they were some of the most difficult ones in the film,” notes Mesa. Wrangling Water Getting physical simulations to behave in a very specific way is never easy. In those shots, Stasiuk’s job was to create simulated gm water elements that would interact with 3D objects such as helicopters and boats. In many of them, a CG boat moves through a polygonal, deforming ocean. Neither element was dynamically driven or simulated, so there was no true fluid interaction. Thus, t@ the RealFlow team had to create the elements to sell the physicality of the shots, “to make the boat look like it was actually touching that ocean,” he says. ar To accomplish this, Stasiuk created a variety of procedural Python scripts for specific natural phenomena, and deployed m those as production tools that would, for instance, maintain stability, create water particles at the waterline of the boats, and te generate breaking waves. He also crafted tools for generating additional passes such as spray and mist from the fluid elements. “This involved developing the methods and scripts, gen- no erating high-quality hero elements for a particular shot, and training artists to use the tools so they could generate elements in other shots,” he says. “They could take 3D elements such ct as boats and ocean surfaces, and quickly simulate interactive effects like realistic whitecaps and boat wakes, providing them ta as rendered elements for the compositors.” This technology allowed Mesa to order up complex, large- cisely fit the director’s requirements. It also resulted in rich, photorealistic fluid behaviors. In one scene, a boat is sinking g, co n scale fluid elements consisting of millions of particles that pre- CG motion, and the CG water reaction generated by placement that would shoot out of the boat as well tin as waves that would bang against the sides of the boat. “A lot of water would be displaced coming off the boat as it began to submerge,” notes Mesa. And in that was done using Stasiuk’s particle system. In another exciting 18-second all-CG shot, a dis- pr tressed cargo ship is tossed about during a storm as its load—cars and debris—is spilled into the sea. Again, the same water surfacing methodology from Flash Films Works, supplemented by Stasiuk’s particle tech- an CW cuers. In addition to the mechanical motion, the Flash Film Works, the crew also needed water dis- nology, was used to achieve the enormous splashes In this dramatic all-CG scene, 3D objects aboard a digital cargo ship spill into the sea as waves crash against the boat.

While the animated characters are simple line drawings, they express emotion and convey the message of the song. 38 | Computer Graphics World CW Digital fine art can assume numerous forms. Many of us are accustomed to viewing 2D, 3D, and 4D wall-hung works that fall into the category of CG art. In reality, these are just the tips of the virtual iceberg: Digital fine art is not limited to an image that can be printed. Nor is it something that only can be seen. Rather, computer-generated selections can have dimension (for instance, sculptures created on the computer and output using stereolithography) or virtual dimensionality (a hologram). Some embrace sound, while others entail motions, either through cooperative interactive participation, electronically mediated performances, or animation. During the past few months, Computer Graphics World has highlighted a number of unique and interesting works that were featured in the Intersections art gallery during SIGGRAPH 2006. Most of those selections fell into the interactive or wall-hung categories. This month we are taking a look at art animations, which shared gallery space with the more traditional—as well as untraditional—pieces.

Instead, they use a range of methods to create an animation, often with a global message. And at the center of those animations is usually imagery that, in its raw form, exists in reality. an For instance, in “Akkad,” Pierre Henon uses a variety of software and hardware to craft a moving array of traffic that illustrates how concentrated populations, mass transportation, architecture, and town planning are resulting in an isolation of the rc le people, drowning them in a hurried crowd. Here, real imagery is “artfully” arranged using digital methods to show this concept. In addition to “Akkad,” other art animations from Intersections are featured on Clockwise from top: Fall of Antioch Students created this film in a Film & Animation class at the University of Applied Sciences in Nuremberg, Germany, and were inspired from listening to music on the Windows Media Player with the Particle Visualization engaged. Among the tools used to create the piece were Softimage XSI, After Effects, Inferno, and more. Swim For this striking music video, Sil van der Woerd used Maya, Tracker, Final Cut Pro, After Effects, and other tools to craft a unique synthetic space for this film, whose simple focus is the power that brings us all to life. As such, the atmosphere is organic, yet there is still somewhat of a clinical feel to it.
