Polygon tables are an essential component in computer graphics for representing complex objects composed of polygons. The process of setting up polygon tables involves organizing and processing a set of input data points to define the connectivity between vertices, edges, and faces. In this article, we will explore a procedural approach to establish polygon tables … Read more
Polygon representations are widely used in computer graphics to model three-dimensional objects. When it comes to representing a cylinder, choosing an efficient polygon representation is crucial for accurate visualization, manipulation, and efficient computation. In this article, we explore an efficient polygon representation for a cylinder and justify its suitability based on several factors, including accuracy, … Read more
In graphic scenes, there are various objects such as trees, flowers, clouds, rocks, water, bricks, wood paneling, rubber, paper, marble, steel, glass, plastic, and cloth. Due to the diverse nature of these materials, there is no single method that can encompass all their characteristics. To create realistic displays of scenes, we need accurate representations that … Read more
When we create and display a 3D scene, there are many things to think about besides just the position in 3D space. Objects can have different shapes, like planes or curves, and sometimes we need to show what’s inside them. Graphics software often has features to display the insides or cutaway views of objects. Transforming … Read more
A graphical user interface (GUI) is a type of user interface that allows users to interact with electronic devices through graphical elements such as icons, buttons, windows, and menus. It provides a visual representation of the system’s features and functions, making it easier for users to interact with the software or hardware. GUIs offer a … Read more
In computer graphics, structures and hierarchical modeling play significant roles in creating and organizing complex virtual scenes and objects. Let’s delve into these concepts further: For example, in 3D modeling, structures might involve the arrangement of vertices to form polygons, which, in turn, create the surface of an object. These polygons can be organized into … Read more
Two-dimensional (2D) viewing in computer graphics refers to the process of displaying and manipulating objects or scenes in a two-dimensional space. It involves transforming and projecting objects onto a two-dimensional plane, typically a computer screen, to create the illusion of depth and perspective. In 2D viewing, the objects are represented using coordinates in a Cartesian … Read more
By utilizing the procedures for displaying output primitives and their attributes, we can generate various pictures and graphs. Additionally, in numerous applications, there is a requirement to modify or manipulate displays. Design applications and facility layouts are developed by arranging the sizes and orientations of the individual components within the scene. Moreover, animations are created … Read more
Output primitives refer to basic graphical entities used to create images on a computer screen or other output devices. These primitives are fundamental building blocks that can be combined to create more complex shapes and images. Here are some common attributes of output primitives: These attributes can be adjusted and combined in different ways to … Read more
Filled-area primitives refer to basic geometric shapes filled with color or texture. These shapes can be used in computer graphics and design to create solid or shaded regions. Some commonly used filled-area primitives include: These filled-area primitives serve as the foundation for creating more complex shapes and graphics in various applications, such as computer-aided design … Read more
