3D Animation fundamentally comprised of triangles, also known as faces or polygons. Each polygon is made up of vertices and edges.Perceive motion as a series of images played back in rapid sequence. Each image differs slightly from the one before it. Animation is the creation of these images.
3D Animation is the process of applying motion to a 3D object.
Animating 3D objects is very similar to animating in 2D, the process of stop-motion animation. An object’s location or appearance is set for specific moments in time. When these movements are played back in sequence, you get a 3D animation.
In traditional animation, lead animators draw the important poses and then handed the drawings off to an inbetweener to fill in the blanks.
Animated characters use a skeletal system to drive their motion. This is referred to as a Rig, and consists of a hierarchical set of connected bones, much like a human skeleton, and controllers to help the animator pose the character. Each bone is manipulated by an animator to create different poses for animation.
The resulting data can be used to track people/animals, robots, deformation of objects, etc.
Rendering is the process of converting models into pixels for storage in an image or to display on screen. When CG movies are created, each frame of the film is sent to a series of computers to be generated into an image.This process can take hours, even years, depending on the length of the film and the number of computers producing the images.
It is most commonly used in the Entertainment Industry for films or video games.
It is used heavily in the advertising industry.
Architectural spaces are expensive and traditional models are limited. Creating an architectural space in 3D allows for easy revision and presenting of designs.
Geometric Modeling has been tightly integrated with the fields of Engineering and product design for many years.
3D models can be used to generate working prototypes or molds. In this process, 3D models are sent to a 3D printer, which converts them into tangible objects by layering materialto build up a 3D form.
