In the code below, you're using Group_Primitives for the normal
attribute. It should be Group_Points.

Just to test I was also using the position vector for the normal
vector (the way Sphere.cpp does, if I am not mistaken), but still
PoissonMesh errors because it thinks no normals are defined. Is there
something I forgot? Please see the geometry_engine below:
oid xyzReader::geometry_engine(Scene& scene, GeometryList& out)
{
std::ifstream in(filename());
int obj = 0;
out.add_object(obj);
PointList* points = out.writable_points(obj);
Attribute* cf =
out.writable_attribute(obj,Group_Points,kColorAttrName,VECTOR4_ATTRIB);
Attribute* normals = out.writable_attribute(obj, Group_Primitives,
kNormalAttrName, NORMAL_ATTRIB);
Vector3 pos;
Vector4 col;
int r, g, b;
int n = 0;
while (in.good())
{
out.add_primitive(obj, new Point(Point::POINT,1.0f,n));
in >> pos.x >> pos.z >> pos.y >> r >> g >> b;
pos.x=-pos.x;
points->push_back(pos);
cf->add(1);
col.set(r/255.0f,g/255.0f,b/255.0f,1.0f);
cf->vector4(n) = col;
normals->add(1);
normals->normal(n) = pos;
++n;
}
std::cout<<"number of points loaded: "<<n<<std::endl;
}
