Graphics & Image Generation

Computer graphics is a field that combines art and technology to create digital images. Depending on the image generation technique, there are two basic types of graphics: raster and vector.

Raster graphics are the act of creating images from points of a specific color, called pixels. Examples of images generated in this way can be digital photographs or scans of documents.

Vector graphics, unlike raster graphics, are based on the mathematical description of shapes using vectors. It is a technique used, for example, in the creation of logos or illustrations, which require maintaining sharpness even with a significant change in scale.

Digital collectibles, such as digital art, often use vector graphics because of its scalability and precision.

Digital tools and computer graphics have also made it possible to create NFTs, i.e. indivisible digital tokens that are closely linked to unique works and can function as certificates of authenticity for works of digital art.

A key aspect in generating graphic images is choosing the right technology depending on the application. It is worth remembering that both methods have their advantages and limitations, which are taken into account when choosing the right tools for a particular graphic design.

Non-interactive graphics, that is...

Non-interactive graphics refer to computer-generated digital images that do not require or respond to user interactions. This type of graphics is presented in the form of a ready-made image or visualization, created on the basis of predefined data.

When viewing a non-interactive graphic, the viewer is in the role of an observer who has no influence on the formation of the image. For example, POV-Ray uses a three-dimensional scene definition file to produce a rendered final image without any further intervention by the viewer.

The distinctive features of non-interactive graphics are:

• Constant image quality: Regardless of the scale, this graphic retains its quality without Distortion.     
• Limited editing: Although you can edit individual objects before after the final image has been generated, the finished result can no longer be modified.
• File size: For simple images, the size of the files can be relatively small compared to interactive graphics files.
  
  

Interactive graphics, i.e. ...

Interactive graphics provide users with dynamism and the ability to influence visual graphic elements in real-time. It is the basis for many modern applications, including computer games, educational programs and virtual reality. A key feature of interactive graphics is the ability not only to receive, but also to actively participate in the visualization process.

Applications:

• Video games 
• education       
• Virtual Reality
• Simulations

In the context of interactivity, digital collectibles and NFTs are also becoming important, especially in the virtual space. Interactive graphics allow users not only to display such objects, but also to manipulate them within a given digital environment.

Interactive graphics use both raster and vector techniques to create dynamic images. In this case, the smoothness of the animation and responsiveness to the user's actions, which are achieved with the use of complex computer algorithms, are important. Images are generated in real time, and their quality has a fundamental impact on the user experience.

Technological challenges:

• ensuring smooth animations
• low Interaction Latency
• complex algorithms that generate images
  

The boundary barrier between the real and virtual worlds is becoming more and more blurred, and interactive graphics play an important role in this phenomenon.

Real-time graphics, i.e. ...

Real-time graphics is one of the fields of computer graphics that allows images to be dynamically generated and displayed in response to user actions. It is characterized by the fact that the updates of the scene take place very quickly, often dozens of times per second, which ensures fluidity and continuity of visual perception.

In this category of graphics, low-poly models are distinguished, which have a relatively small number of polygons, thus allowing for faster graphics processing, which is crucial for maintaining high performance of applications in real time. Despite the lower detail, it is often used in games and simulators.

High-poly, on the other hand, presents models with a large number of polygons, which provides a more detailed and realistic image, but can negatively affect performance, especially in applications that require quick graphics updates.

Applications of real-time graphics include, but are not limited to, computer games, simulators, virtual reality, and  information  and graphics portals. They allow users to interact with virtual environments, being a key element for the visual experience.

The development of technology, including AI methodologies, opens up new possibilities for real-time graphics. AI-based methods can increase its efficiency and quality, as well as make it easier to create more complex scenes without compromising performance.

Nowadays, real-time graphics are encountered not only in games, but also in architecture, automotive or even during video conferences, which shows its versatility and importance in modern multimedia technologies.

Computer graphics is an incredibly versatile field that combines art and technology to create digital images. From raster and vector graphics, to non-interactive, to interactive and real-time graphics, each type has its own unique applications and technologies. Digital tools and advances in technology, including AI, are opening up new possibilities for creators and users, allowing them to create more advanced and interactive visualizations. Computer graphics play a key role in many areas of life, from education to entertainment to professional applications in engineering and medicine, underlining its importance in the modern world.
