Definitions: The Building Blocks of Computer Graphics
Computer graphics is the field of creating and displaying images that appear on computers, TV’s and mobile devices. It is made up of several different basic components, referred to as the building blocks of computer graphics.
Pixel is the basic ‘building block’ of computer graphics. This is the point in an image or graphic that appears on a screen. The image resolution is determined by the number of pixels, or picture elements, that appear in a given area.
Texture is an additional property of a graphic, and it describes how it looks and feels. Textures can be used to make an image look and feel smooth, bumpy, or rough.
Computer Animation is a form of computer graphics that allows a user to create and control images and their motion in two- and three-dimensional space. Animation can be used for presentation, entertainment, and visual storytelling.
Lighting and shadowing is used in computer graphics to give a sense of realism. It makes an image appear three-dimensional by adding variations of light and shadow.
Surfaces are the mathematical descriptions of shapes, such as cylinders, spheres, planes, etc. These surfaces are used to form objects in a 3D image or scene.
Graphic Effects are used to give added interest to a scene or an image. These effects are used to create a visual illusion of depth, motion, color, texture, and other elements.
Color Model is a system or method used to define the colors of an image. It is used to create a realistic representation of colors in an image.
Line Art is descriptive drawing or illustration made up of line edges such as circles, ovals, rectangles, and other shapes. It is used to describe an object, such as a human face, and can be used to create digital images.
Filter is a type of software that is used to modify the colors or an image as well as to manipulate the textural elements of an image. It can be used to make an image more realistic or to create a specific effect.
CAD stands for Computer Aided Design. This is a type of software used to design two- and three-dimensional models which can then be used to create 3D images for any number of applications.

Transforming 2D into 3D: What are the Basic Building Blocks?
Two Dimensions Becoming Three
Although two-dimensional shapes and illustrations might seem limited, computer graphics are capable of generating versatile 3D animated models that are realistic and captivating. The fundamental elements of this type of imagery are the basic building blocks, which consist of shapes, lines, colours and textures. These allow the creator to create almost anything imaginable from the simple to the complex.
The Challenge of Transformation
Have you ever wondered how two-dimensional assets are realistically transformed into 3D images? It can be quite daunting for a graphic artist to take a set of flat shapes and colours and turn it into a mesh of realistic and interactive 3D models. Without the right techniques and software tools, this can be an especially difficult task.
One of the most important elements of this transformation process is the construction of an accurate 3D mesh. A mesh is created when geometric shapes are interconnected to form a three-dimensional object. A variety of approaches can be taken to create a professional mesh, depending on the type of shape and the desired level of realism. For instance, a designer may choose to render realistic curved lines with the help of a spline algorithm, or employ the “tessellation” function to form a grid of flat triangles.
By combining these methods, a three-dimensional image can quickly come together. After that, other important components become available, such as the textures, scenes, and lighting. Colours, textures, and shadows can then be added to the 3D model to create an incredibly realistic image.
Making the Difference
The result of transforming two-dimensional assets into an interactive and captivating 3D rendering is what makes graphic design stand out. It offers the chance to turn simple objects into fascinating environment tails. For example, a realistic urban skyline can be created by cleverly combining building shapes, textures, shadows, lighting, and animation. The result is a realistic 3D animation that has the power to draw people in and leave a lasting impression.
All this complexity begins with the basic building blocks of computer graphics, which are the cornerstone of a 3D animation. With the right combination of these shapes, lines, colours, and textures, a designer can take a simple concept and create an exceptionally realistic 3D environment that offers endless possibilities for exploration and interaction.
