Hello! Everyone, I have Object placed inside a box and i used distance sensors to get the distance of the object from a reference point (0,0,0), now i want to plot the surface of this object using MATLAB, but i am confused, which plotting function to use.

Suppose the object placed is cylindrical object as shown below.

These are the valid points which i get from the sensor from point (0,0,0) and all of these points are same across the z-axis

x = (89.26772163,89.2251516,89.17737906,89.05573047, 88.8611554,88.59463961,88.2572044,87.84990611, 90.60990337,93.38333305,96.16835842,98.96312702, 101.7657715,104.5744107,107.4709263)

y = (86.20483673,83.20379993,80.29567276,77.41496542, 74.56336272,71.74252458,68.95408524,66.19965255, 65.83194826,65.38771374,64.8663768,64.26740613, 63.59031171,62.83464514,62.04836823)

How can i plot using these points to get the image as follow:

With the points above, it is not possible to draw the complete image, but at-least it is possible to draw the boundary of the front side. Please suggest which type of plot, surface plot i can use.

Assuming those distances are in meters, the 10nm sensor resolution you have there is so impressive you should share with us what it is.
