Three-Dimensional Computer Animation Erli Ling

Introduction Animation Animation all moving imagery involves a sequence of still images played back quickly enough for your eye to see them as continuous 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 still images are produced individually is known as animation

Computer-generated animation Computer-generated animation the impact of this goes well beyond what you normally think of as 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. it also used to produce movie special effects, video games, scientific simulations, architectural walk-throughs.video games scientific simulations architectural walk-throughsvideo games scientific simulations architectural walk-throughs

Techniques Traditional techniques Traditional techniques The most basic technique: to draw and then photograph each frame one by one 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 Technical advances made: the use of transparent sheets (cels), onto which were painted different layers of a scene

Computer techniques 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 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 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.

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

Rendering Rendering the computer processes the three-dimensional data that define your model to produce flat, two-dimensional representations of the model 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 see-through wireframe-> hidden-line-> shaded renderingsee-through wireframe-> hidden-line-> shaded renderingsee-through wireframe-> hidden-line-> shaded rendering

Animation Animation a series of still images that, when played back in quick succession, appear as continuously moving 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 much of 3D CG is based on key-framing approach postproduction postproduction compositing + editing compositing + editing

Conclusion The basic steps to produce 3D computer animation 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 design and planning -> modeling the shape of an object -> rendering the surface of an object, the lighting, the use of the camera -> animating -> postproduction
