Doubt regarding Assignment 1 (Optional One)

[ppriyank]

I have downloaded the assignment 1, and set up the libigl
After completing the "First Steps with Libigl"
I download the the github repository in a fresh new folder and again do the cmake and make file thing.

I can see the executable "./ex1_bin" but no mesh.o object. still running the command "./ex1_bin mesh.o"
I see

IOError: mesh.obj could not be opened...
Assertion failed: (F.cols() == 3), function doublearea, file GM_Assignment_1master/external/libigl/cmake/../include/igl/doublearea.cpp, line 27.
Abort trap: 6

Can some one help on how to proceed?

It requires a mesh as input, you can launch it with:

./ex1_bin ../data/bunny.off

or use any other file in the data folder.
