Mesh decimation of an area of interest

I have a script that creates both a custom colormap highlighting an area of interest (grey) and then plotting this area using this code to make a patch in green. I want to preform mesh decimation only on the green plot and not on the whole figure on the colormap.

Plot the triangle
        patch('Vertices', vertices, 'Faces', facesInRange(i, :), 'FaceColor', 'green');
    end

Hi Maryam!

I understand that you are trying to perform mesh decimation only on the part of the green area created by the “patch” function in your code.

I would suggest storing this green patch in an object, let’s say “p”, and then passing “p” to the “reducepatch” function to perform the mesh decimation.

For more information on the “patch” function and how to store and access it as an object, refer to the following documentation page: https://www.mathworks.com/help/matlab/ref/patch.html#d124e1107225:~:text=the%20previous%20syntaxes.-,p%20%3D%20patch(,),-returns%20the%20patch

For more information on the “reducepatch” function, refer to the following documentation page:
