The 3D modeling of games requires an art foundation. The computer is two-dimensional and based on relevant knowledge of color science. The protruding parts on the edge of three-dimensional objects generally show high-brightness colors, while the concave parts generally show high-brightness colors. Part of it appears dark due to light blocking. In this way, you need to use art to render related colors. If you don't have an art foundation, it will be more troublesome to use it.
In addition, for example, if the 3D text is to be drawn, a high-brightness color is displayed in the original position, and its outline is outlined with a low-brightness color in the lower left or upper right position, which will visually produce the appearance of 3D text. effect. These all require the use of art foundation.
Extended information:
3D is the abbreviation of three-dimensional, which is three-dimensional graphics. Displaying 3D graphics on a computer means displaying three-dimensional graphics on a plane. Unlike in the real world, there is a real three-dimensional space with real distance space.
The computer only looks like the real world, so the 3D graphics displayed on the computer look just like reality. One characteristic of the human eye is that when the near side is large and the far side is small, it will form a three-dimensional sense.
Computer screens are flat and two-dimensional. The reason why we can appreciate real-life three-dimensional images is because the different grayscales of colors when displayed on the computer screen create visual illusions for the human eye. , and perceive the two-dimensional computer screen as a three-dimensional image. Based on relevant knowledge of color science, the protruding part on the edge of a three-dimensional object generally appears in high-brightness color, while the concave part appears in dark color due to being blocked by light.
This understanding is widely used in drawing buttons and 3D lines on web pages or other applications. For example, the 3D text to be drawn displays a high-brightness color in the original position, and uses a low-brightness color to outline its outline in the lower left or upper right position, which will visually produce the effect of 3D text.
In specific implementation, the exact same font can be used to draw two 2D texts of different colors at different positions. As long as the coordinates of the two texts are appropriate, different visual effects can be produced. 3d text.
