Three-Dimensional Computer Animation Erli Ling
Introduction • Animation all moving imagery involves a sequence of still images played back quickly enough for your eye to see them as continuous still images are produced individually is known as animation
Computer-generated animation the impact of this goes well beyond what you normally think of as animation. it also used to produce movie special effects, video games, scientific simulations, architectural walk-throughs.
Techniques • Traditional techniques • The most basic technique: to draw and then photograph each frame one by one • Technical advances made: the use of transparent sheets (cels), onto which were painted different layers of a scene
Computer techniques • The first program developed in NYIT focused on two-dimensional animation and enabled the animator to produce automatically what are called the “in-between” frames. • The next step entailed applying this same principle to three-dimensional animation.
The computer automatically generated the in-between positions and rendered each position as a frame of animation. • Today three-dimensional computer animation is no longer limited to mimicking the techniques of traditional cel animation
Basic steps • Storyboard a sequence of images and verbal descriptions describing the intended animation 3D storyboard sample
Modeling developing a mathematical, wireframe representation of any 3D object via specialized software
Rendering the computer processes the three-dimensional data that define your model to produce flat, two-dimensional representations of the model see-through wireframe-> hidden-line-> shaded rendering
Animation a series of still images that, when played back in quick succession, appear as continuously moving much of 3D CG is based on key-framing approach • postproduction compositing + editing
3D video demos • Jinghua City View • Music • Pixar production • Animator vs Animation • Chicken • 3D water • Bear golf • 3ds max tutorial
Conclusion • The basic steps to produce 3D computer animation design and planning -> modeling the shape of an object -> rendering the surface of an object, the lighting, the use of the camera -> animating -> postproduction
