Mar 22, 2023 · 2D Transformation in Computer Graphics | Set 1 (Scaling of Objects) We can use a 2 × 2 matrix to change or transform, a 2D vector. This kind of operation, which takes in a 2-vector and produces another 2-vector by a simple matrix multiplication, is a linear transformation.

In a graphics API, there will be certain basic shapes that can be drawn with one command, whereas more complex shapes will require multiple commands. Exactly what qualifies as a basic shape varies from one API to another.

When a transformation takes place on a 2D plane, it is called 2D transformation. Transformations play an important role in computer graphics to reposition the graphics on the screen and change their size or orientation.

OpenGL (Open Graphics Library) is a cross-platform, hardware-accelerated, language-independent, industrial standard API for producing 3D (including 2D) graphics. Modern computers have dedicated GPU (Graphics Processing Unit) with …

With this chapter, we begin our study of computer graphics by looking at the two-dimensional case. Things are simpler and a lot easier to visualize in 2D than in 3D, but most of the ideas that are covered in this chapter will also be very relevant to 3D.

In two-dimensional (2D) computer graphics, geometric shapes such as lines, circles, and polygons are defined using coordinate systems. Each point in the image is represented by a pair of coordinates (x, y) that correspond to its position on the screen or image canvas.

Shapes are at the heart of 2D graphics. All user interfaces are built on a foundation of rectangles, a simple but important shape. Text rendering is composed of glyphs, each of which is a shape on its own.

The most common curves used to generate computer graphics pictures are... Bezier (curves, surfaces, patches)... B-spline (curves, surfaces, patches)... Fractals... Graftals... Complex three-dimensional graphic objects can be modeled, viewed, and displayed using... Modeling... Viewing... Parallel projection... Perspective projection...

With these classes you can create virtually any geometric shape and render it through Graphics2D by calling the draw method or the fill method. Example : ShapesDemo2D.java.

Mar 14, 2019 · In this article we're going to look at some of the basic geometric constructs we commonly use in computer graphics, with an emphasis on those for real-time graphics and games. We'll look at points, lines, 2D and 3D shapes, as well as classifying transformations.
