Hi,
I'm writing a script for Blender and need to build a face array. My
engine needs that all faces must be triangles, so I convert quads to
triangles by dividing them into two triangles. Here is the function:
def build_face_table(mesh):
face_table = {}
i = 0
for f in mesh.faces:
if len(f.v) == 3: # triangle
face_table[i] = f
i += 1
elif len(f.v) == 4: # quad
f1 = NMesh.Face()
f2 = NMesh.Face()
f1.mat = f.mat
## f1.normal = copy.deepcopy(f.normal)
f1.normal = NMesh.Vert(f.normal[0], f.normal[1],
f.normal[2])
f1.v.append(f.v[0])
f1.v.append(f.v[1])
f1.v.append(f.v[2])
f2.mat = f.mat
f2.v.append(f.v[2])
f2.v.append(f.v[3])
f2.v.append(f.v[0])
face_table[i] = f1
i += 1
face_table[i] = f2
i += 1
else:
message = "Can't build face from 2 vertices."
Draw.PupMenu("Face Table Error%t|"+message)
return
return face_table
Everything seems be ok, but i'm getting:
Traceback (most recent call last):
File "<string>", line 169, in write
File "<string>", line 102, in build_face_table
AttributeError: normal
I was wondering why? Though the face has an attribute called "normal"!
Just simply test:
nv = f.normal
and it works! But why my new faces (f1 and f2) no?
Greetings.
