We all know 3D as an amazing visual experience in movies, games and images – to the point that it appears like how it is in real life. But there are so much more about 3D graphics that many of us don’t know yet. Let’s discover them here.
3D (Three-Dimensional) Graphic Arts is also known as CGI (computer graphic imagery). It uses design techniques in order to “give life” to images, video game characters, and movie animations to name a few. To come up with realistic visuals and smooth motion graphics, a freelance 3D designer uses more advanced and quite skeptical design methods compared to 2D arts.
Working on Shapes
Shapes are everywhere in real life. Some are even unidentified. The same thing applies to graphics. They are also made up of straight lines and various shapes. However, the shapes in real life are not as sharp and edgy as the shapes we have in math classes and graphic templates. To create images that would have smooth curves like those in our faces and other objects, 3D designers layer or put together different shapes to achieve the desired lifelike output. This composition is called wireframe.
Achieving the Texture
We can tell so much about the texture of a real object from a distance. Sometimes we need to observe from several angles to be sure, or even touch it to confirm if it is soft, hard, sharp, slimy, rough, etc. This is the most challenging part for 3D graphics. How can they make the viewer feel the texture of the object? Well, because 3D graphic designers are very talented, they can make this possible. They follow three steps to do it. If one of the three is inaccurate, the illusion of reality will not be achieved.
The artist needs to determine the color of the object. Does it contain only one color? How about shading? If the object is a rose, does the artist need to use different shades of red for the rose?
Secondly, he/she needs to know its texture. Does it contain bumps or it appears soft? Are the irregularities on the surface? After that, they would refer to texture maps to determine what kind of shape they need to layer to formulate the design.
Lastly, the designer recognizes the amount of light the object reflects. For example, when light reflects on the knife, you’ll know that is a sharp object. This also applies to plants, trees and other objects.
