If anybody sees someone videotaping next to him, they have the co-chair's permission to beat th e living daylights out of them. By the way, it won't matter. We have two gian t electromagnets just inside the door. When you leave we're going to turn them on. REEVES : John and I got this idea at last year's SIGGRAPH. You come to SIGGRAPH every year and go to the film show , and everything is so slick. It's just great most of the time. Bu t behind the scenes there's a lot of effort, a lot of horror storie s and a lot of bloopers. We thought we'd have a session abou t that. LASSETER : Over the past few years at Pixar, Bill, Eben and I have started saving some of our more ridiculous mistakes, such as when the rendering just doesn't go quite right and the head i s about the size of a pin. We started saving those thinking tha t some clay we'd like to show them and so we're able to sho w them here. We told AV this is about bloopers, so if they screw up , then it's all part of the show. We left the form of this sessio n open so that if Bill and I heard of some more silly thing s occurring in films that were made this year, we would add them. Since the panel was formed we've added two more speakers and I think you'll really enjoy their stories. . We'd like to start with our first speaker. Put your hands together for a big SIGGRAPH welcome for Mr. Loren Carpenter of Pixar. I've been given the dubious honor of speaking first. I don't know what that means in this situation, but the first thin g we're going to do is show you a film, Vol Libre, I did about nine years ago. There is sound on this, but I don't want it very lou d because I'm going to talk over it. There are a couple of stories with this film.

Blinn","doi":"10.1145/77276.77287","DOIUrl":"https://doi.org/10.1145/77276.77287","url":null,"abstract":"My name is Demetri Terzopoulos and my co-chair, John Platt, and I would like to welcome you to the panel on Physically-Based Modeling -- Past, Present and Future. I'll start by introducing the panelists; the affiliations you see listed on the screen are somewhat out of date. I'm Program Leader of modeling and simulation at the Schlumberger Laboratory for Computer Science in Austin, Texas, and I was formerly at Schlumberger Palo Alto Research. I'll speak on the subject of deformable models. John Platt, formerly of Cal Tech, is now Principal Scientist at Synaptics in San Jose, California. He will be concentrating on constraints and control. Alan Barr is Assistant Professor of computer science at Cal Tech. Last year he received the computer graphics achievement award. He'll speak about teleological modeling. David Zeltzer is Associate Professor of computer graphics at the MIT Media Laboratory. He will be speaking on interactive micro worlds. Andrew Witkin, formerly of Schlumberger Palo Alto Research, is now Associate Professor of computer science at Carnegie Mellon University. He will speak about interactive dynamics. Last but not least, we have with us James Blinn, who of course needs no introduction. Formerly of JPL, he is now Associate Director of the Mathematics Project at Cal Tech. He says he'll have several random comments to make against physically-based modeling. I was also asked by the SIGGRAPH organizers to remind the audience that audio and video tape recording of this panel is not permitted. Many of you are already familiar with physically-based modeling, so I will attempt only a very simple introduction to this, in my opinion, very exciting paradigm. Physically-based techniques facilitate the creation of models capable of automatically synthesizing complex shapes and realistic motions that were, until recently, attainable only by skilled animators, if at all. Physically-based modeling adds new levels of representation to graphics objects. In addition to geometry -- forces, torques, velocities, accelerations, kinetic and potential energies, heat, and other physical quantities are used to control the creation and evolution of models. Simulated physical laws govern model behavior, and animators can guide their models using physically-based control systems. Physically-based models are responsive to one another and to the simulated physical worlds that they inhabit. We will review some past accomplishments in physically-based modeling, look at what we are doing at present, and speculate about what may happen in the near future. The best way to get a feel for physically-based modeling is through animation, so we will be showing you lots of animation as we go along. I would like to talk about deformable models, which are physically-based models of nonrigid objects. I have worked on deformable models for graphics applications primarily with Kurt Fleischer and also with John Platt and Andy Witkin. Deformable models are based on the continuum mec","PeriodicalId":405574,"journal":{"name":"ACM SIGGRAPH 89 Panel Proceedings","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116091319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I assume you all can see me -- thats why these lights are here. My name is Chris Schmandt from the Media Lab at MIT. I'm co-chairing this panel with Barry Arons, who is sitting over here. It's actually quite a pleasure to co-chair this panel with Barry. We've been working together off and on for more years than I care to remember. This panel has a long ridiculous name. Basically it's about audio and window systems and workstations. I'm wearing two hats here. I'm going to spend a minute or two introducing the panel and then I'm going to spend some time talking about my own segment of the panel. We're going to try to be a panel as opposed to a series of five mini-papers that never get published. In other words, we're going to try to keep our presentations relatively short, then segue into a series of prepared questions that the panelists are going to answer amongst themselves. Then we'll open the floor up for questions. In some ways this is a very incestuous crew. We've all known each other for quite a while. We have different slants and we're actually going to try to focus on those slants a little bit. So if we disagree with each other, that doesn't necessarily mean we really hate each other. We're all friends. Where this panel is coming from is a surge of interest in audio, and multimedia, in general, in computer workstations. The Macintosh has had audio for quite a while -- you may or may not choose to call that a workstation. The NeXT computer sort of surprised people by having fairly powerful DSP and audio in and out. You'll get a demo of that later if you haven't seen it. The Sun SPARCStation has come out with some primitive digital record and playback capabilities. On the other hand, there's been interest in voice in computer workstations for years and years, and what we've seen so far is that voice really hasn't had very much success. There have been a number of products that have come and gone. What has become popular has been centralized service -- specifically voice mail. Voice mail is tied in more to a PBX -- and the interface is more like a telephone than it is a mouse and window system, in the computer workstation interface. Obviously, window systems are here to stay. We're not suggesting that audio is going to replace the graphical paradigm, but rather have to interact with it. On the other hand, everybody has a telephone. People had telephones on their desks before they had workstations, and we talk all the time at work. Voice really is a fundamental component of the way we talk, the way we interact with each other. What we're seeing in terms of the technologies showing up in these workstations is higher bit rate coding. Gone are the days of unintelligible low bit rate linear predictive coding or something like that -- except for specialized applications. Speech recognition is here, but it's in its infancy. Text-to-speech -- it's around, it's difficult to understand.

My name is Dorothy Spencer, and this is a special session entitled Computer Art - An Oxymoron? Views from the Mainstream.Before I introduce the panel members I want to tell you two things briefly about the session. First I'm going to tell you what the session does not focus on, and to do that I'm going to read from the SIGGRAPH 89 Show daily that came out this morning. So, for any of you that read it and came here expecting to hear museum curators, gallery owners and artists discuss the evolution of computer art as a means for artistic expression, you can go away now; we're not going to do it.What we are going to do is talk about the fact that computer generated imagery --- although it's been around for several decades, the mainstream art world has been slow to acknowledge it as a viable medium for the creation of fine art. There have been few computer art exhibitions and even fewer reviews. Like photography, is computer art going to take three-quarters of a century before it's accepted into the mainstream?Is it partially the fault of the artist? Are artists too wrapped up in the technological processes to be concerned with the aesthetic results?Does the majority of the artists using the computer not participate in regular juried shows because they feel their work is not understood?Does the technology need to be understood before the work can be judge aesthetically?These are just a few of the questions that we hope to discuss this morning and hopefully we'll have answers for. After each panelist has made his or her presentation, we'll let the panelists respond to each other's remarks before we let you people loose with questions and answers.My first panelist is Harry Rand. He's curator of painting and sculpture at the Museum of American Art in Washington, D.C. He'll be followed by Kathy Huffman, She's the director of the Institute of Contemporary Art, Boston. Followed by Philip Pearlstein, internationally-known artist and former professor of painting at Brooklyn College; Bob Riley, curator of media art, San Francisco Museum of Modern Art; Will Stapp, curator of photography of the National Portrait Gallery; and Vivian Rainer, art critic for the New York Times. We hope you enjoy the session. Thank you.","PeriodicalId":405574,"journal":{"name":"ACM SIGGRAPH 89 Panel Proceedings","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127726109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I promised everyone I would come out wearing the data suit, but it just slipped my mind and I never got around to it. Actually Marvin Minsky was saying that the thing to do would be to come out with nothing on because that would be the perfect interface to the computer. So I kind of shunned the whole thing off at that point.We just heard Nicholas Negroponte ask us -- \"how do we communicate with computers?\" Well, that's why this panel is here today. We'll be discussing virtual environments and interactivity with some of the people who have been doing a lot of work in this field. I was interviewing a lot of people last night at the parties about virtual environments and I realized that everyone has their own idea of what their virtual environment will be. Some want to interact more, others less. Some want little people running around on the screen bringing them all sorts of messages or images. We'll be hearing about a lot of different types of interactivity on our panel today.I'd like to point out that Margaret's slide should also include the MIT Media Lab as well as UNC.I'm going to show some tapes and do some talking later on so I'd like start of by introducing Jaron Lanier. He's the guy with the dreadlocks you've seen at the Silicon Graphics booth. He has an amazing collection of musical instruments from all over the world and when he plays them, he transports you to other times and other places.

Wray","doi":"10.1145/77276.77290","DOIUrl":"https://doi.org/10.1145/77276.77290","url":null,"abstract":"Good morning. My name is Tim Heidmann and I'd like to welcome you all to this panel, which is entitled Future Directions in Desktop Video, and I'd especially like to thank all you people who stayed up a little late on Thursday night to come to this panel. It's really good to see you all out there. I've gotten word that this panel is being transcribed. They're putting together a booklet, so they're taking the slides and the stills from the videos and all the things that we're saying. So I'd just like to take this opportunity to say hi to the person who's transcribing this and sorry you couldn't be here today, and I wanted to let you know that the word of the day is Neopraseodymium, and I hope you've got your scientific dictionary close by. When we first started putting this panel together, I talked to my friends who were involved in a number of different areas in video, and the question that came to the forefront very quickly is what exactly desktop video is. There's been a lot of talk about it, a lot of magazine articles. It's a good buzz word. But we all felt it incorporated a whole bunch of different areas that weren't easily put into one category. We did agree that the name of desktop video came from the field of desktop publishing. In desktop publishing, which has been a rapidly growing field in the past few years, the whole point is that we've got a computer bringing together elements from the outside world, creating elements inside the computer, putting them all together and coming up with a final product. The point is it's all done inside the computer. Again, it does the things that computers do really well -- like text editing and graphics design and layout. And it was made possible by the fact that these high quality printers -- laser printers -- had come out that you could produce a very high quality output from it. Well, on the video side, there is a similar development. That is, it's possible now to make video animation completely within the computer. There are software packages for modeling objects, for creating animation, for rendering very high quality images and outputting them directly to tape. And I guess you could call that desktop video. You're doing the same thing as you're doing in desktop publishing, but now you're producing videotape and animation. But really what's happening in video is a lot bigger than that. I've kind of come up with this map. If you look at the entire video process, you can split it into four parts. The first being creating the elements, which I've called Source here. Now that would include such applications as computer graphics, generated completely inside the computer, but also things like pointing a camera at someone or something, things like medical imaging. Basically the creation of the images. The second step would be assembling those images and probably some audio into a master video production. Just about everything you do in video involves some sort editing to it, even if it's just putting a t","PeriodicalId":405574,"journal":{"name":"ACM SIGGRAPH 89 Panel Proceedings","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127800211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
