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
