What does modeling really do

3D modeling in layman's terms is the use of three-dimensional production software to build a model with three-dimensional data through virtual three-dimensional space.

3D is an abbreviation for three-dimensional, or three-dimensional graphics. To display 3d graphics in a computer is to display three-dimensional graphics in a plane. Unlike the real world, computers just look a lot like the real world, so a 3d graphic displayed in a computer will look like the real thing to the human eye. The human eye has the property of being large near and small far, which creates a sense of three-dimensionality. Computer screen is two-dimensional, the reason why we can appreciate the three-dimensional image, because displayed on the computer screen when the color grayscale difference and make the human eye to produce a visual illusion, and then the two-dimensional computer screen perceived as a three-dimensional image. For example, to draw 3D text, i.e., in the original position to display high brightness color, and in the lower left or upper right and other positions with low brightness color outline, will be visually produce the effect of 3d text.
