toggle view projection between "orthographic" and "perspective"

Description

During design of technical components the orthographic makes more sense for view(0,0), view(0,90) etc.

Algorithm (Workflow)

This function, toggleviewprojection, is designed to toggle the view projection of a plot in MATLAB between "orthographic" and "perspective". It is part of the SolidGeometry library and was introduced in version 5.4.

Input Parameters

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

Algorithm Steps

  1. Retrieve the current projection type of the active axes using get(gca, 'Projection'). This returns either 'orthographic' or 'perspective'.
  2. Check if the current projection is 'orthographic'.
  3. If it is 'orthographic', change the projection to 'perspective' using set(gca, 'Projection', 'perspective').
  4. If it is not 'orthographic' (i.e., it is 'perspective'), change the projection to 'orthographic' using set(gca, 'Projection', 'orthographic').
  5. Check if there are no output arguments expected from the function using nargout == 0.
  6. If no output is expected, print the current projection type to the command window using dbprintf('projection is now: "%s"', get(gca, 'Projection')).

Output

The function does not return any output. It modifies the current axes' projection and optionally prints the new projection type to the command window if no output is expected.
