In a world where people never stop trying new things, revolution and development happens every day. It is due to this fact that technologists have shifted focus from the common 2D computer graphics to 3D computer graphics. 3D which stands for three dimensional graphics are 2D optical illusions that plays some tricks in your mind and makes you see objects in a 3D dimension. It can also be described as any object that can be represented on a three axis system which is the X, Y, Z axes. X is horizontal, Y is vertical and Z is the depth.

It is important to note that the Z- axis is very important in computer graphics. The Z- axis helps to measure the depth of an object, the distance of an object, the location of an object and the Z- axis of rotation.

Basic Points about 3D Computer Graphics

It is important to note that unlike in the real world whereby 3D objects can be physically represented in the three dimensions, the 3D objects can only be represented mathematically in the digital world.

3D models refer to any representation of an object in the digital space.

With 3D computer graphics, you do not need to do the calculations yourself since there are 3D software that help solve the calculations. Some of the software environments have some built in real time render engines that make it possible for 3D graphics to be represented with semi-realistic textures, shadows and lighting.

3D models cannot be restricted to any practical space.

How to Do 3D Computer Graphics

3D computer graphics consists of three essential parts. The first part is the 3D modeling which is responsible for defining the shape of the object. The models that are used in 3D graphics come from two different sources. One originates from a modeling device in a computer used by an engineer or an artist while the other source originates from sources that are scanned to a computer from an actual object. The second part of 3D computer graphics is layouting and animation which seeks to define the movement and position of the objects within the setting. The last part of the graphics is positioning which helps define the spatial relationship of the object considering its size and place.

For a beginner, the above is very vital information as it helps you to understand some of the important basics of 3D computer graphics. Take it to learn about it and you will be amazed of the amazing objects you can create.
