What is a science and technology painting? Be specific.

This painting is the work of the painter Ruan Jia, which is a high level in the original painting. I don't know if you are talking about high-tech painting. . .

As far as I know, I use hand-drawn boards and computers as painting tools to create paintings. Some are drafted directly by computer, and the whole process is completed by computer. Some are hand-painted first, and then scanned into the computer with a scanner for coloring.

Well, that's all. I ordered it wrong just now. I have to add something.
