Algorithm (Workflow)

This function, VLFLplothide, is designed to interactively hide or delete a graphical patch object in a 3D plot using user input. Below is a detailed explanation of the algorithm and its parameters:

Input Parameters

The function VLFLplothide does not take any input parameters. It operates on the current figure and axes in the MATLAB environment.

Algorithm Steps

1. Disable 3D Rotation: The function begins by turning off the 3D rotation feature using rotate3d off. This is necessary to ensure that the subsequent user input is not affected by any interactive rotation of the plot.
2. User Input: The function waits for a single mouse click input from the user with ginput(1). This input is used to select a point in the current figure.
3. Select 3D Object: The function calls select3d, which is assumed to be a custom or library function that returns information about the 3D object at the selected point. The outputs [a,b,c,d,e,h] are used, where h is the handle to the graphical object.
4. Check Object Type: The function checks if the selected object is a patch using ispatch(h). This is a logical check to determine if the handle h corresponds to a patch object.
5. Delete Patch: If the selected object is a patch, the function deletes it using delete(h). This effectively removes the patch from the plot.
6. Enable 3D Rotation: Finally, the function re-enables 3D rotation with rotate3d on, allowing the user to interactively rotate the plot again.

Assumptions and Dependencies

• The function assumes that select3d is available and correctly implemented to return the necessary information about the selected 3D object.
• The function operates on the current figure and axes, and it does not create or modify any new figures or axes.
• The function is part of the VLFL-Lib, as indicated by the header comment.

Conclusion

The VLFLplothide function provides a simple interactive mechanism to hide or delete patch objects in a 3D plot based on user input. It leverages MATLAB's graphical input and object handling capabilities to achieve this functionality.
