  • Patent number: 11625158
    Abstract: A method for displaying simulation images through clicking and rolling operations is provided. A client device executes an application program to display a carrying object on a display unit. Then, the application program generates a click event at the carrying object according to the client device and produces the corresponding event result by displaying at least one structural object on the carrying object. When the click event ends, at least one template object is loaded. The client device then rolls and thereby removes the carrying object such that the at least one structural object is superimposed on the template object to complete a superimposed display.
