WriteSTL_Improve.cpp

Hi Tezza2010

What is improved in this version ?

I see you add a normal, but your do not calculate the normal

you simply repeat a vertex.

fprintf(fp,

"facet normal %f %f %f\n"

,mat->hReal[0][i],mat->hReal[1][i],mat->hReal[2][i]));

Anyways, I have created a normals function, now saving normals to the STL file as you suggest above and to be frank I can not tell the difference in Creo.. which I believe Creo computes the normals in the rendering engine
