the convexHull is not computed correctly

[diguaseven]

int MinimumZoneFitPlane(const Point* pointsIn, int lengthIn, PlaneKernel* outLseg)
{
ConvexHull hull(pointsIn, lengthIn);
std::list faces = hull.GetFaces();
std::vector vertexs = hull.GetVertices();
std::vector pointT(vertexs.size());
for (int i = 0; i < vertexs.size(); i++) {
pointT[i].x = vertexs[i].x;
pointT[i].y = vertexs[i].y;
pointT[i].z = vertexs[i].z;
}

std::string filePath = "D:/CMM/PlanePointsVertex.csv";
WritePointsCSV(pointT.data(), pointT.size(), filePath.c_str());

return Geom3DError::OK;

}
The above is the call code for computing the 3D convex hull, the result is not correct;
