It focuses on the mathematical and computational foundations of image generation and processing rather than purely aesthetic issues. Computer graphics is often differentiated from the field of visualization, although the two fields have many similarities. One of the first displays of computer animation was Futureworld , which included an animation of a human face and hand—produced by Ed Catmull and Fred Parke at the University of Utah.
There are several international conferences and journals where the most significant results in computer graphics are published. The subfield of geometry studies the representation of three-dimensional objects in a discrete digital setting. Because the appearance of an object depends largely on its exterior, boundary representations are most commonly used. Two dimensional surfaces are a good representation for most objects, though they may be non-manifold.
Since surfaces are not finite, discrete digital approximations are used. Polygonal meshes and to a lesser extent subdivision surfaces are by far the most common representation, although point-based representations have become more popular recently see for instance the Symposium on Point-Based Graphics.
In fact, it can be disastrous to spend hours working on a file and have it in the wrong format. Artwork in the wrong file format might be:. All of these will result in costing your more time and money.
The good news is: experienced business savvy designers will know from experience exactly which file type to use for each specific circumstance.
For those looking for a little extra knowledge, or gluttons for punishment, here is a quick synopsis of when to use which file type:. The downside to this format is that compressing the image too much will cause it to visibly degrade and look jagged. Gifs do an incredible job of compressing images and making them suitable for fast downloads. In contrast to the. One added bonus is that the.
Sometimes the artwork has a sharp, unattractive border when the image's background invisible, when this happens, go with the next file type, the.
