Computer Graphics

Computer graphics are what make computer screens so fun to look at. What would computers be without graphics? Things would be quite a bit more difficult to learn without that handy image/graphic to reinforce all the concepts we learn everyday while online. The fact is that computer graphics are quite necessary and rendering them wasn't always an easy task.

There are a few different stages when it comes to generating visual images, and the first of them is 2D image or pixel computations. These deal with rotating or displaying images in a certain defined area and shape on the screen. Then things get a bit more complicated when you get into curve computations. These have to do with Bezier curves and matching these curves to other shapes to create images. Finally, we get into 3D computations. This involves rotating a 3D point or computing volumes of 3D shapes. It also involves taking a number of 2D objects and creating a 3D object from them, such as a mesh texture. It also involves intersection of objects in 3D and whether or not they are touching. These are just some of the light starter concepts when you begin to look into how computer graphics work and the algorithms behind them.
