The invention discloses a visual three-dimensional code touch screen compiler product and its programming technique. According to the invention, visual geometric programming and three-dimensional code programming are realized; a programmer can finish programming work by one-hand or two-hand touch screen operation, therefore the workload of the programmer is greatly reduced; and the programming work is driven to humanized and intelligentized development. The built-in technologies of the new type geometric decoder and three-dimensional compiler of the invention comprise: generating a code plate and selecting a code element, coding a rule, information expression, hexadecimal number expression, conversion of digital and geometric codes, plane code to three-dimensional code, and so on; the functions of the compiler comprise: a touch screen function, program three-dimensional coding, a three-dimensional code paraphrasing function, an intelligent detection function, an automatic code storage function, an automatic connection function of three-dimensional code chains, and so on. According to the invention, the program code is converted into a shape code; a new pattern is provided for the security operation of the program; each code chain is not divided, so there is no leak for an external virus program to implant; the program is effectively prevented from being tampered and attached; and the program security is improved.
