Computer graphics is the science of using mathematical algorithms to convert two-dimensional or three-dimensional graphics into the raster form of a computer display. Simply put, the main research content of computer graphics is to study how to represent the graphics in the computer, and use the computer to carry on the calculation, processing and display of graphics related principles and algorithms.
The development of CAD also shows the trend of intelligence. According to most popular CAD software at present, the main function is to support the drawing and output of the product's subsequent stages. The product design function is relatively weak, and the most commonly used function of AutoCAD is interactive drawing.
