I am testing https://github.com/johnyf/fig2u3d to convert Matlab figures to u3d. I have set up it with its dependencies,

Then I tested its examples, it fails to convert figures with surfaces. it works fine if there are no surfaces in the Matlab figure.

It was originally written for Matlab 2012 and I am testing it on the 2020 version few minor problems is with functions isnan.

another problem with the dependency function mesh_normals it is not returning empty matrix instead of the proper direction of normals, that I have changed/corrected.

Now it is generating the IDTF file properly but while converting it to u3d with IDTFconverter it giver error.

In the process of debugging, I find that the program to write the IDTF file from fig is not detecting surfaces or patch, they are returning empty matrix.

after running the program the command window shows

test_fig2u3d_contour_surf Warning: Axis aspect ratio unequal. Exported U3D will look different.
