1. Scientific visualization is an interdisciplinary research and application field in science, which attaches great importance to the visualization of three-dimensional phenomena, such as various systems in architecture, meteorology, medicine or biology.

2. Information visualization Information visualization is to study the interactive visual representation of general data to strengthen human cognition. General data includes digital and non-digital data, such as geographic information and text.

3. Visual Analytics Visual analysis is a new field formed with the development of scientific visualization and information visualization, focusing on analysis and reasoning through interactive visual interfaces.

definition

Visualization is a theory, method and technology that uses computer graphics and image processing technology to convert data into graphics or images, display them on the screen, and conduct interactive processing.

It involves many fields, such as computer graphics, image processing, computer vision, computer-aided design and so on, and becomes a comprehensive technology to study a series of problems such as data representation, data processing and decision analysis. At present, the rapidly developing virtual reality technology is also a visualization technology based on graphics and images.

application area

Visualization technology was first applied to computer science and formed an important branch of visualization technology-scientific computing visualization.

Visualization of scientific calculation can turn scientific data, including measured values, images or digital information involved in calculation, into intuitive physical phenomena or quantities that change with time and space, so that researchers can observe, simulate and calculate.
