|The artist caressed the velvety crimson rose with his brush, adding a subtle dimension of color. No painters palette his medium. At his hand, a primitive digital tablet and stylus with which he lovingly applied each layer of electronic paint, waiting patiently for the image to re-render with every new stroke.
Even though he was absorbed with his creation, Alvy Ray Smith III sensed Ravi Shankars aura immediately, the musicians perfume wafting to his nose from several feet away. As was common, a colleague was showing off the Lucasfilm labs in San Rafael, Calif., where Smith and others were experimenting with nascent digital graphics technology. Smith was expected to provide a quick demonstration of what wonders could be worked.
After a quick tutorial, he made a random gesture on the tablet with his stylus. Everyone is feeling good because were seeing the future, Smith recalls thinking. And then, the magic took hold: The green line formed by his casual stroke gracefully looped up toward the rose on the screen, endowing it with a delicate stem. Shankar virtually vibrated with pleasure, and Smith stared at the display in wonder.
It was just one of the best things that has ever happened to me, Smith, 61, whispers, still awed with the telling years later.
Today, his feat may sound trivial. But nothing to do with art or computer graphics has ever been trivial to Alvy Ray Smith, who combines the soul of an artist with the mathematical intellect of a computer scientist. It is this unique combination and Smiths tireless work in creating software that could emulate the qualities of paint on a PC that have cemented his place of honor in the annals of computer industry history.
My first impression was that here was this gentle giant, or graceful giant, who was as excited as me about moving the pixels around on a computer screen, says David DiFrancesco, a longtime colleague who met Smith in the early 70s through Xerox PARC.
There, it was Smiths job to create the art for an experimental computer paint program developed by another one of his career-long collaborators, Dick Shoup. Smith used Shoups system to develop animated characters walking patterns or random color sequences, drawing on a book written by Preston Blair, who contributed the dancing hippos sequence to one of Smiths favorite animated works, Fantasia.
Smith output his own ideas onto one-inch videotape in a series called VidBits. He recalls: I had a vision of what I could be doing. It was making pictures with the computer and making them move.
We all had interests from varied fields of expertise that we had gained in college or life experiences, recalls DiFrancesco, still a senior scientist at Pixar. Some of us had math and some had engineering, some had arts, optics and so forth. Every one of us came with more than one. Alvy certainly brought the two-dimensional paint program in all its glory, and he came from a computer science background.
Indeed, Smiths Ph.D. dissertation from Stanford University was on cellular automata theory, a branch of physics that looks at the state of objects in space and time, a field that he would later apply to his animation work.
Smiths 84-year-old father, Alvy Ray Smith II, says his sons interest in art emerged early, pointing to early photography experiments that kept him out of teenage mischief. His talent would also provide a turning point during Smiths engineering study at Stanford, when he won a local art contest he had entered on a whim. They didnt understand what he was doing before that, the elder Smith says.
Aside from his artistic sensibilities, former colleagues said the good-natured Smith often helped nurture technical projects behind the scenes, buffering the engineers from the business side. It was a very organic kind of management, says Loren Carpenter, senior scientist at Pixar. What Alvy did was act as an intermediary.
Smiths decision to leave Pixar in 1991 to found Altamira Software was born of his revelation that the personal computer, which he had largely ignored up to that point, could bring graphics technology to more creative souls. The Iceman technology birthed at Pixar, based on its Image Computing Exchange Language (ICICLE) and then extended at Altamira, was used to create a whole set of programming interfaces that made it easier to handle digital images. Apparently, Microsoft agreedit moved to acquire the company in 1994, retaining Smith as a fellow for about five years.
Smith retired in 1999 to work on what he calls old man projects, including genealogies for his parents. He received two awards for his book about his mothers branch of the family and now is working on his dads side.
Marsha Rising, an officer of the American Society of Genealogists, who corresponds regularly with Smith, says he has quickly established himself as a serious researcher. Alvy wants to learn, she says. Hell ask. He recognizes where hes strong and where he needs to learn, and that is unusual.
When hes not dabbling in family trees or reading dozens of scientific treatises and history books, he steeps himself in digital photography. Chances are, we havent heard the last of Smith when it comes to technical breakthroughs that will revolutionalize the culture of art.
I like to talk to artists. I do it a lot. And what I like to tell them is, Dont take the machines as theyre given to you. Dont take the software as its given to you, Smith muses. The computer is the most malleable tool thats ever come down the pike. And one of the things that most of the rest of us need the artists of the world to do is to tell us what in the heck it is we have here. What is this medium? What can we do with this thing? So far, only the technical people have explored it and told us whats going on there. But I know theres a lot more.
