output normal direction of wall

Submitted by shokeyi on Sun, 08/18/2013 - 18:19

Hi everyone,
According to the dump code, it could output the stl style of wall with the normal direction. However, I want to call it in the source code. Does anyone know how to modify the code? I found the "dump_mesh_stl.cpp" source code has the definition of the "surfaceNorm". Is it to call this code to obtain it?
