Hi
arwtyxouymz <arw.tyx-ouy_mz at ezweb.ne.jp>
vtkBestFitPlane could help you, or just using the following code (input
array of points or one point)
void computeBestFitNormal(std::vector<vtkVector3d> v, int n/* vector
size*/, vtkVector3d& vNormal)
{
double resultX;
double resultY;
double resultZ;
const double *p = v[n - 1].GetData();
const double *c;
// Iterate through the vertices
for (int i = 0; i < n; i++){
// Get shortcut to the "current" vertex
c = v[i].GetData();
// Add in edge vector products appropriately
resultX += (p[2] + c[2])*(p[1] - c[1]);
resultY += (p[0] + c[0])*(p[2] - c[2]);
resultZ += (p[1] + c[1])*(p[0] - c[0]);
// Next vertex
p = c;
}
vNormal.Set(resultX,resultY,resultZ);
vNormal.Normalize();
p = nullptr;
c = nullptr;
}
