How to create computer graphics – a beginners guide
Very often, when the phrase “computer graphics” is used, they mean graphics used in computer games, because that is where it is important.
Computer graphics in games for beginners will seem like a rather complicated element, but knowing certain basics, as well as the types and types of graphics in games, you can stop being afraid of it.
Moreover, computer graphics are not only games but also:
- a virtual reality;
- cool web design;
- 3D printing;
- architectural visualization;
- effects for cinema;
- and much more.
Today we will talk about computer graphics, touching on the topic of creating graphics for games. Matrix is used in 2D and 3D graphics. To find the determinant of a matrix, an online matrix determinant calculator is available.
Types of graphics in games
Computer graphics in modern games are of 2 types: 2D and 3D or 2D and 3D graphics. Each of these is divided into its own kinds and types, depending on the method and its implementation.
Types of graphics in games: 2D graphics and their types
The history of graphics in games dates back to the 40s when the first slot machines were invented, and a canvas of ordinary light bulbs acted as a screen. It is difficult to call it graphics, but it all started that way. Then there was a long development of graphics in games and its gradual improvement. 2D graphics in games first appeared in the 80s but became widespread in the second half of the 90s.
To date, 2D graphics are still used in computer games but are not as active as 3D. But a few words about two-dimensional graphics need to be said.
There are the following types of 2D graphics in games and not only:
This is a set of simple geometric elements, such as. The point, line, circle, rectangle, etc. In general, this kind of 2D graphics is used as icons and logos for websites. Used less often in games. A distinctive feature of such graphics is the ability to scale and deform without loss of quality.
Such graphics are based on a matrix of pixels, where each pixel has some value or a combination of color, light, transparency, etc. The main disadvantage of such graphics is a higher “weight”, as well as loss of quality when scaling. However, this is the type of graphics most often used in games.
Whatever one may say, two-dimensional graphics are gradually becoming obsolete. This does not mean that it will completely disappear, but the time will come when it will be used in minimal quantities, and 3D will confidently take its place.
Types of graphics in games: 3D graphics
Three-dimensional graphics are a trend in modern computer graphics. It is widely used in everything from small objects on websites to computer games and movies. It is impossible to briefly describe all the processes associated with the creation of three-dimensional graphics in games. Not least because they are quite diverse, and to become a specialist in the field of 3-D, you need long enough to learn and a lot of practice.
But to lift the veil and tell everything is as simple as possible.
Computer 3D graphics for beginners
No matter, for which you will create a three-dimensional object, you need to know some of the concepts, properties:
This is one of the most popular technologies for creating 3D objects, where each object is described by a large number of vertices and faces that connect them. In simple words, any of your objects will be a geometric figure consisting of a “mesh”. You will deform this “mesh” until it takes the shape of the object you need.
The object that you modeled will now need to be textured to make it look as realistic as possible. This includes giving the color, transparency, opacity, and so on . to your object.
To make an object as realistic as possible, it is not enough just to add the necessary texture. It is very important that the light on it is correctly adjusted. For this, there are point and global light sources that can be used depending on the situation.
Creating a realistic subject with the right lighting isn’t everything either. What is it for if it won’t move? Therefore, any object will need animation. For this, a “skeleton” is created for the object and the process of changing its appearance is controlled depending on its movement.
Creating an object and animating it is already an achievement, but when there are several objects, how to combine them? Composite – this is the process whereby perish dit combining multiple animated objects in one frame.
CPNS be several objects and place five of them into a single frame – this may be enough for a full game scene. When you need to give more visual effects, come to the aid of particle simulation. In fact, it is a system of free points in space that you can use at your own discretion. From them, it is possible to make a fire, water, sand, the effectiveness of explosions or magic, and t. D.
Computer Graphics for Beginners: Tools
No need to believe so eat, who says that to work in 3D you need to know the basics, and having one on hand is a good tool for the job. We first need to prepare theoretically for Xia to work with computer graphics.
To do this, you can take specialized courses, read books or find yourself a good mentor, and then you can proceed to search for tools.
As for the tools for creating computer graphics, there is a huge field for choice. Famous companies, such as Pixar and Disney, use expensive software or software personal development.
Among the cool and expensive programs are:
- 3DS Max,
- and etc.
However, a novice specialist is unlikely to want to spend a lot of money on specialized software, so many people stop at free Blender. Although it is free, its capabilities are not inferior to many paid “brothers”.
