I have set the drawing to be performed taking into account the scene lights, with:
For the DrawPoly command, I use the normals that I get from the Phong tag, with:
BaseTag* phongtag = op->GetTag(Tphong,0L);
If i is the index of the face that I get the coordinates of, I get the normals of the points of the polygon with:
However, the polygons are drawn with the correct color but with the incorrect shading (illumination).
How can I set the normals to make it display correctly?
p.s. By the way, if there is no Phong tag, I simply use the normal of the face with:
N = CalcFaceNormal(pt_list, pol);
and fill the normals array with:
But this also produces erroneous shading.
