Hi,
Yes, it is possible to select points from a 3D plot using mouse clicks and save them in an array. One way to do this is to use the "datacursormode" and "getCursorInfo" functions in MATLAB.
Here's an example code that demonstrates how to do this:
% Load your mold mesh data and plot it
load('mold_mesh.mat')
trisurf(triangles,vertices(:,1),vertices(:,2),vertices(:,3))
% Enable data cursor mode
dcm_obj = datacursormode(gcf);
set(dcm_obj,'DisplayStyle','datatip','SnapToDataVertex','off','Enable','on')
% Initialize an empty array to store selected points
selected_points = [];
% Wait for user to select points and press enter to stop
disp('Select points on the mesh using mouse clicks. Press enter to stop.')
while true
% Wait for user to click on a point
pause
c_info = getCursorInfo(dcm_obj);
if isempty(c_info) % User pressed enter
break
end
% Get the coordinates of the selected point
point = c_info.Position;
% Add the point to the array
selected_points = [selected_points; point];
end
% Print the selected points
disp('Selected points:')
disp(selected_points)
In this code, the "datacursormode" function is used to enable data cursor mode, which allows the user to select points on the plot using mouse clicks. The "getCursorInfo" function is used to get the coordinates of the selected point, which is then added to the "selected_points" array. The loop continues until the user presses enter to stop selecting points.
Note that this code assumes that the mold mesh is stored in variables named "triangles" and "vertices". You may need to modify the code to match your specific mesh data format.
