1. Three-Dimensional Computer Animation
Erli Ling

2. 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

3. 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.

4. 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

5. 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.

6. 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

7. Basic steps Storyboard
a sequence of images and verbal descriptions describing the intended animation
3D storyboard sample

8. Modeling
developing a mathematical, wireframe representation of any 3D object via specialized software

9. 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

10. 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

12. 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

13. Apply
animation, television-commercial graphics, feature-film market. Industrial designer, architects, interior designer, sculptor, biologist, chemist, medical professionals

14. Software
Most popular 3D modelers: 3D studio Max, Alias, Blender (open source), Maya, LightWave
Free modelers available via the Internet: Blender, Wings 3D, K-3D, SmoothTeddy, SketchUp
