rotation around an edge

i want to determine the orientation sequences of the stl file. does anyone have an idea. i have written the code but it revolves around a specific point not the edge..you can see the image when i rotate 90 gard around y axis

figure
gm = importGeometry("Teil1.stl");
pdegplot(gm)

vertices = gm.Vertices;

%xs3 = s3.Vertices(:,1);
%ys3 = s3.Vertices(:,2);
%zs3 = s3.Vertices(:,3);


% Define the point around which to rotate the figure
point = vertices(1,:) ; % change the values according to your desired rotation point

% Rotate the figure around the specified point
gm2 = rotate(gm,90, [1 0 0], point)

figure
pdegplot(gm2)
% Rotate the figure around the specified point
gm3 = rotate(gm2,90, [0 0 1], point)
figure
pdegplot(gm3)
gm4 = rotate(gm3,90, [0 0 1], point)
figure
pdegplot(gm4)
vertices = gm.Vertices;

gm5 = rotate(gm4,90, [1 0 0], point)
figure
pdegplot(gm5)

It's not clear to anyone which edge you're trying to rotate around, or whether the point you chose is on that edge.

Hi,

From your question I understand that you wanted the image to be rotated along a particular edge instead of a point . You can use a function called

imrotate()

to do the same.

Refer the code below to apply the same according to your needs.

% Read the image
im = imread('your_image.jpg');

% Find the edge pixels along the top edge <this you can find using your
% image>
edgePixels = [1: size(im,2); ones(1,size(im,2))];

% Rotate the image by 90 degrees along the edge
rotatedIm = imrotate(im, 90, <method> , edgePixels(:,1));

% Display the rotated image
imshow(rotatedIm);

OP has no images to rotate. They have a DiscreteGeometry object and a set of line and patch objects created by pdegplot().

jetzt ich will eine methode zur Bestimmung des Energiepotentials zwischen den Posen finden
