Algorithm (Workflow)

This function, camlightdelete, is designed to remove all light sources of type 'Light' from the current axes in a MATLAB figure. It is part of the SolidGeometry library, specifically for visualization purposes.

Input Parameters

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

Algorithm Steps

1. Retrieve all child objects of the current axes using get(gca, 'Children'). This returns a list of handles to all objects contained within the current axes.
2. Identify objects of type 'Light' using findobj(h, 'Type', 'Light'). This function searches through the list of child objects and returns handles to those that are of type 'Light'.
3. Delete the identified light objects using delete(li). This command removes all light sources from the current axes, effectively deleting any lighting effects applied to the 3D plot.

Output

The function does not return any output. Its effect is visual, as it removes lighting from the current plot.

Example Usage

The function can be used in a sequence of commands to manipulate lighting in a 3D plot:

SGbox;        % Create a 3D box
camlightTL;   % Add a light source
pause;        % Pause to view the effect
camlightdelete; % Remove the light source
