1, different modeling dimensions.
C4D literally means 4D movie, but it is also a 3D demo software. C4D can be used for 3D modeling and drawing, and CAD refers to using computers and their graphic devices to help designers design, mainly for 2D modeling and drawing.
2. Different application fields.
CAD: Now the advanced CAD application system has integrated a series of functions such as design, drawing, analysis, simulation and processing, including architectural design, structural design, equipment design, urban planning, urban traffic design, municipal pipeline design, traffic engineering design, water conservancy engineering design and other engineering design and management.
CAD technology can complete the design of printed circuit board, which will be used in simulation animation, light industry, textile, home appliances, clothing, shoemaking, medical care and medicine, and even sports.
C4D: Now, C4D is involved in the special effects production of many blockbusters. In terms of product appearance design, C4D technology is also needed.
Computer aided design technology;
CAD technology mainly refers to computer-aided technology based on medical images, which is different from computer-aided detection. The latter focuses on detection, computer marks abnormal signs and provides common image processing technology without diagnosis. It can be said that computer-aided diagnosis is the extension and ultimate goal of computer-aided detection.
Computer-aided detection is the basis and necessary stage of computer-aided diagnosis. Some people call CAD technology the doctor's third eye. Using CAD system is helpful to improve the sensitivity and specificity of doctors' diagnosis. With the development of modern high technology, modern high-definition imaging equipment, such as DR, CT, MRI and PET, provides great convenience for the diagnosis of clinical diseases.
However, although functional imaging represented by PET is very helpful for clinical diagnosis, due to the limitation of conditions, in more cases, doctors still make judgments based on morphological information provided by modern imaging and their own clinical experience. Due to individual differences and the limitations of doctors' observation and mastery of image information, sometimes it is inevitable to make mistakes in judgment or mistakes.
