What does 3D animation mean?

Is to describe this person as abnormal.

Three-dimensional refers to the space system formed by adding a direction vector to plane two. Three dimensions are not just the three axes of the coordinate axis, that is, the X axis, the Y axis and the Z axis, where X represents the left and right space, Y represents the front and back space, and Z represents the upper and lower space (the spatial direction cannot be understood by the plane rectangular coordinate system).

In practical application, the left-right movement is generally described by X axis, the up-and-down movement is described by Z axis, and the back-and-forth movement is described by Y axis, thus forming a three-dimensional sense of human vision.

Three dimensions are composed of one dimension and two dimensions, that is, two dimensions only intersect in two directions, and one dimension and one dimension are superimposed to get three dimensions.

Three-dimensional is three-dimensional, and the front, back, left, right and up are only relative to the observation angle. There is no absolute front, back, left, right, up and down.

The way 3D animation technology simulates real objects makes it a useful tool. Because of its accuracy, authenticity and unlimited maneuverability, it is widely used in many fields such as medicine, education, military affairs, entertainment and so on. In the production of film and television advertisements, this new technology can give people a refreshing feeling, so it has been welcomed by many customers.

Three-dimensional animation can be used to make special effects (such as explosion, smoke, rain, light effects, etc.). ), special effects (crash, deformation, illusory scenes or characters, etc. ), advertising product display, title flying and so on.
