Calculate Area of 3D points

Hi everybody,

i need to calculate the area of 3D points representing a leaf. How can i do it?

Thank you,

Riccardo

Hi @ Riccardo Rossi,

Try using the polyarea function in Matlab to calculate the area of the polygon formed by the points. For more information on this function, please refer to

https://www.mathworks.com/help/matlab/ref/polyarea.html#

Finally, display the calculated area using disp function along with the area value converted to a string for proper display. Here is an example code snippet to help you understand.

% Define the 3D points representing the leaf

points = [1, 2, 3; 4, 5, 6; 7, 8, 9; 10, 11, 12];

% Calculate the area of the leaf

area = polyarea(points(:,1), points(:,2));

% Display the calculated area

disp(['The area of the leaf is: ', num2str(area)]);

Please let us know if you have any further questions.

If all points on a plane are in 3D space, you could create a polyshape object by using polyshape and then use the area function to calculate the area.
