This custom UI component mainly imitates the Cube View view function of some commonly used 3D modeling software. For example, 3DSMAX, Maya, Revit, etc., all of them have this small tool of Cube View in the 3D operation interface, which is very convenient for designers or users to view a certain focused 3D model. This Widget plug-in is mainly used in BIM and GIS fields, and can also be used in Games or other industry applications. Its performance consumption is very small, even almost negligible. The operation is very simple, the continuity is also very strong, and there will be no obvious problem of viewing angle freeze. There are a total of 6 faces, 8 sides and 8 corners, and the camera viewing angles can be switched arbitrarily without affecting the operation of the free camera. The way to add this Widget component is also very simple, just drag and drop it in without any additional configuration. Of course, I also left some code interfaces to expand its functions.
