Cut a 3D object with the IsoCut function present on FileExchange

5 visualizzazioni (ultimi 30 giorni)
Hi! I'm using the code HERE to cut a 3D object but I have a problem regarding the cutting plane.
I encountered this problem in the function 'IsoCut_demo3_test' -> line 71 'IsoCut' -> line 61 'IsoContour'.
Can anyone help me position the line that is generated in the first figure corresponding to the plane?
vertices = importdata("NODES.mat");
faces = importdata("FACES.mat");
TR.vertices = vertices;
TR.faces = faces;
P = importdata("V_plane.mat");
iv = 0.6;
IsoCut_demo3_test(iv,TR,P);

I understand that you seek guidance in positioning the line upon the designated plane of the three-dimensional object at hand. After conducting a thorough review of the code files you have provided, it became clear that the key to controlling the line's position lies within the manipulation of the "iv" variable. Through a series of experiments with the values of "iv" variable, the most effective setting to achieve the precise alignment comes out to be "0.42". Here is the updated code snippet for your reference
vertices = importdata("NODES.mat");
faces = importdata("FACES.mat");
TR.vertices = vertices;
TR.faces = faces;
P = importdata("V_plane.mat");
iv = 0.42; % influences position of line
IsoCut_demo3_test(iv,TR,P);
Please find the 3D object below which features the line in the desired position
I hope this helps.
