  2. Introduction • Animation is an art form created and cultivated over the last century. • Through animation, new worlds can be imagined. • This modern art form evokes emotion through the movement of a sequence of drawings, paintings, photographs or rendered images. IMD2214 - Chapter 1: 3D Computer Graphics

  3. Introduction • Digital characters and sets can now be built and animated, then presented in different media formats such as film, video and interactive games. • Characters and visual effects can even be seamlessly integrated into live-action footage. IMD2214 - Chapter 1: 3D Computer Graphics

  4. 3D Computer Animation • The use of 3D graphic tools is now an important part of many television, film and multimedia projects. • The way objects appear in perspective, the way a surface bends and twists, or the way a light illuminates a space—all of these complex 3D effects can now be recreated on the computer. IMD2214 - Chapter 1: 3D Computer Graphics

  5. 3D Computer Animation • Broadcast • Animated Short Films • Feature Films • Visual Effects • Interactive Video Games • Visualization and Web IMD2214 - Chapter 1: 3D Computer Graphics

  6. Broadcast • 3D computer graphics has had to animate a flying logo as a new and dynamic way of getting the message across. • Flying logos are now integrated into more complete 3D environments where a product is advertised or a corporate message introduced. IMD2214 - Chapter 1: 3D Computer Graphics

  7. Broadcast • Character animation is also used more to bring objects to life and help sell the message. IMD2214 - Chapter 1: 3D Computer Graphics

  8. Animated Short Films • This animated short films were able to tell a compelling story about the influences of our society on the average person. • Short films provide a fertile ground for experimentation that help drive innovation in the computer graphics industry. IMD2214 - Chapter 1: 3D Computer Graphics

  9. Animated Short Films IMD2214 - Chapter 1: 3D Computer Graphics

  10. Feature Films • Before this, many films have integrated 3D into existing live-action scenes. • Pixar’s Toy Story® became the first feature-length animation that used 3D exclusively for characters and sets. • Sony Pictures • Imageworks’ Stuart Little® took this one step further and made a digital mouse the star of a live-action movie. IMD2214 - Chapter 1: 3D Computer Graphics

  11. Feature Films IMD2214 - Chapter 1: 3D Computer Graphics

  12. Visual Effects • Film sets can be partially built and then extended with detailed 3D digital sets. • Animated stunt people can be thrown off buildings in ways not recommended for real people. • smoke, fire and exploding objects can now be simulated within the safety of a computer screen. IMD2214 - Chapter 1: 3D Computer Graphics

  13. Visual Effects • It is ideal for generating visual effects that can be fully integrated into live-action shots. • The best effects make it impossible to find the line between reality and where computer graphics are used. IMD2214 - Chapter 1: 3D Computer Graphics

  14. Interactive Video Games • Video games have developed from black and white pixels to real-time virtual environments built with 3D characters and sets. • Game artwork is becoming more sophisticated with complex 3D models, texture maps, lighting and even dynamics. IMD2214 - Chapter 1: 3D Computer Graphics

  15. Interactive Video Games IMD2214 - Chapter 1: 3D Computer Graphics

  16. Visualization and Web • Digital content creation tools are used in a number of fields including fine arts, architecture, design,education and scientific research. • With advances in the web’s ability to present graphic and 3D information, visualization on the internet is emerging as an important tool for many companies. IMD2214 - Chapter 1: 3D Computer Graphics

  17. Visualization and Web IMD2214 - Chapter 1: 3D Computer Graphics

  18. The Animation Pipeline • The animation pipeline can be summarized in 7 stages: • modeling; • characters; • animation; • materials and textures; • lights and cameras; • effects; • Rendering and compositing. IMD2214 - Chapter 1: 3D Computer Graphics

  19. 1. Modeling • This is the stage where you build geometry to represent objects and characters. • This geometry describes the position and shape of your models and can be manipulated in the 3D workspace. IMD2214 - Chapter 1: 3D Computer Graphics

  20. 2. Characters • Characters are models that use special controls such as skeleton joints and inverse kinematics for animation. • These controls make it possible to create the complex mechanics required by characters. IMD2214 - Chapter 1: 3D Computer Graphics

  21. 3. Animation • Once a model has been setup for animation, you can begin to animate it. • By changing its position or shape over time, you bring it to life. • The timing can then be tweaked to create very specific motion. IMD2214 - Chapter 1: 3D Computer Graphics

  22. 4. Materials and Textures • In order for geometry to be rendered, it must be given material attributes that define how it will be shaded by light. • Texture can also be added to bring detail and visual richness to the surfaces. IMD2214 - Chapter 1: 3D Computer Graphics

  23. 5. Lights and Cameras • As you would on a movie set, you must set up lights and cameras to illuminate and frame objects. • You can then animate both the lights and the camera to further mimic Hollywood effects. IMD2214 - Chapter 1: 3D Computer Graphics

  24. 6. Effects • There are many effects such as fire, fields of grass and glowing lights that can’t be easily represented using models and textures. • Tools such as particles and Maya Paint Effects can be used to add effects. IMD2214 - Chapter 1: 3D Computer Graphics

  25. 7. Rendering and Compositing • Once all the scene’s parts are ready, you can render a single image or a sequence of images. • You can also render objects separately, then bring them back together in 2D using a compositing system. IMD2214 - Chapter 1: 3D Computer Graphics

  26. Production Pipelines • Single Artist • Small Production House • Large Production House • Gaming Company • School/Student IMD2214 - Chapter 1: 3D Computer Graphics
