Projected to the projection plane, and then the coordinates of the click hit position of the 3D rendered logical window can be determined on the projection plane. In this way, the click hit rate of the logical window after 3D rendering can be effectively improved.

FIG. 3 is a flowchart of a method for operating a logic window according to a second embodiment of the present invention, wherein the operation method of the logic window can be applied to a computer system such as a computer, a smart phone, a server, or the like.

Keep the length and width ratio of the logical window after the three-dimensional rendering unchanged, and map the three-dimensionally rendered logical window into the three-dimensional space to obtain a three-dimensional model of the three-dimensional rendered logical window; wherein, the three-dimensional model is marked with three-dimensional rendering The hit point of the logical window's click.

In the embodiment of the present invention, the logical window refers to a logical window (Frame) created by using the full self-painting technology. In the full self-painting technology, the organization structure of Frame is generally as follows: The top-level (or lowest-level) Frame is internally nested with N logical sub-frames, and sub-Frames can be similarly embedded in sub-frames, and so on. A frame with multiple nested relationships. When the window drawing is triggered, the drawing will start from the top-level window. After the top-level window is drawn, draw the next-level sub-window, and then draw the nesting level one level until all the frames are drawn, so that you can get A complete logical window. When drawing a logic window, you can first determine whether the logic window has 3D attributes. If you do not have 3D attributes, you can draw them according to the 2D logic window drawing method. If you have 3D attributes, execute the 3D rendering process. Draw a logical window after 3D rendering.

Correspondingly, as shown in FIG. 6b, the three-dimensionally transformed three-dimensional model can be perspectively projected onto the projection plane according to the position coordinate correction value and the size ratio correction value obtained in step S303.
