(Matlab) Please go to https://www.mediafire.com/file/3b63q1ex0jv41c2/ThinkerASCII.stl to download the file. Rename the attached as Thinker.txt and read the data only, using  sca nf command.

Find the z-co o  r d range (height) of the statue, and remove the bottom 50%.

Re-create Thinker Half .STL using  f print f command. Hint:

(1) The first and last line should be kept as it is. First line: solid Exported from Blender-2.79 (sub 0) Last line: end solid Exported from Blender-2.79 (sub 0)

(2) The STL file is repetition of 7 lines that defines many triangles. First line (facet normal) is the direction vector of the triangle, and 3-5 lines are the (x, y ,z) of triangle vertex. You should find and delete triangles whose vertex z-coordinate is below a critical z value. See my video lecture for more details. facet normal 0.278814 -0.935724 -0.216066
