The term “rendering” may be by analogy with an “artist’s rendering” of a scene. The rendering equation doesn’t account for all lighting phenomena, but is a general lighting model for computer-generated imagery. Rendering’ is 3d rendering for web thesis pdf used to describe the process of calculating effects in a video editing program to produce final video output. With the increasing sophistication of computer graphics since the 1970s, it has become a more distinct subject.

As a product, a wide variety of renderers are available. Some are integrated into larger modeling and animation packages, some are stand-alone, some are free open-source projects. The result is a completed image the consumer or intended viewer sees. Most 3D image editing programs can do this.
A rendered image can be understood in terms of a number of visible features. Some relate directly to particular algorithms and techniques, while others are produced together. Even tracing a portion large enough to produce an image takes an inordinate amount of time if the sampling is not intelligently restricted. Monte Carlo techniques to obtain more realistic results at a speed that is often orders of magnitude faster. These surfaces are usually rendered to the display using one of the other three techniques. Most advanced software combines two or more of the techniques to obtain good-enough results at reasonable cost.

Generally object order is more efficient, as there are usually fewer objects in a scene than pixels. A high-level representation of an image necessarily contains elements in a different domain from pixels. In a schematic drawing, for instance, line segments and curves might be primitives. In a graphical user interface, windows and buttons might be the primitives. In rendering of 3D models, triangles and polygons in space might be primitives. Here, one loops through each of the primitives, determines which pixels in the image it affects, and modifies those pixels accordingly. Rasterization is frequently faster than pixel-by-pixel rendering.
Alternatively, rasterization can be done in a more complicated manner by first rendering the vertices of a face and then rendering the pixels of that face as a blending of the vertex colors. This newer method of rasterization utilizes the graphics card’s more taxing shading functions and still achieves better performance because the simpler textures stored in memory use less space. Sometimes designers will use one rasterization method on some faces and the other method on others based on the angle at which that face meets other joined faces, thus increasing speed and not hurting the overall effect. Where an object is intersected, the color value at the point may be evaluated using several methods. In the simplest, the color value of the object at the point of intersection becomes the value of that pixel. A more sophisticated method is to modify the colour value by an illumination factor, but without calculating the relationship to a simulated light source. To reduce artifacts, a number of rays in slightly different directions may be averaged.
