In a schematic drawing, for instance, line segments and curves might be primitives. These elements are referred to as primitives. When this approach is applied to 3D rendering, one arrives at the most basic version of the ray tracing algorithm.Ī high-level representation of an image necessarily contains elements in a different domain from pixels. In this case, each pixel in the rendered image depends on exactly one pixel in each of the source images, so a pixel-by-pixel technique is the natural approach. This approach is frequently used when one is rendering to perform color balancing, video compositing, and similiar effects. One way to accomplish rendering is to take this description literally: loop over each pixel in the image, and determine based on the high-level description what color should be assigned to that pixel. Which approach is chosen for a given task greatly influences the kind of problems that will have to be solved to create a successful renderer.Īs stated earlier, rendering is the problem of deciding what color each pixel should be, given a high-level representation of an image. There are two large-scale approaches to rendering that can be applied to almost any rendering task. More complicated kinds of rendering include the display of two-dimensional and three-dimensional geometric shapes, such as lines, curves, polygons, and surfaces, and ultimately the production of images that are indistinguishable from photographs of the real world - called photorealistic rendering. A simple type of rendering is the display of text, such as what you are now reading: an application stores a text message in ASCII, for example, and the operating system decides which pixels to make light and dark to reproduce the shape of the letters. Rendering is a broad topic and takes on many different forms. In order to actually display the image, it is necessary to convert the high-level representation into pixels, and this process is called rendering. However, this representation of an image does not lend itself well to "high-level" manipulations, and so images are often created and stored using a high-level, abstract representation that describes the components of the image. In computer science, an image is represented using a regular grid of pixels, each of which has an independent color. The aim of computer graphics is to use computers to generate images, usually images of recognizable subjects, or images that are useful in some other way (such as graphical user interfaces).
