The operator surface_normals_object_model_3dsurface_normals_object_model_3dSurfaceNormalsObjectModel3dsurface_normals_object_model_3dSurfaceNormalsObjectModel3dSurfaceNormalsObjectModel3d calculates the
3D surface normals for the object ObjectModel3DObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3D using the method
specified by MethodMethodMethodMethodMethodmethod. The calculated normals are appended to the
input object and the resulting object is returned in
ObjectModel3DNormalsObjectModel3DNormalsObjectModel3DNormalsObjectModel3DNormalsObjectModel3DNormalsobjectModel3DNormals. Currently, Moving Least Squares (MLS,
MethodMethodMethodMethodMethodmethod='mls'"mls""mls""mls""mls""mls") is the only normals estimation method
that is supported.
The MLS method for normals estimation is essentially identical with
the MLS method used by smooth_object_model_3dsmooth_object_model_3dSmoothObjectModel3dsmooth_object_model_3dSmoothObjectModel3dSmoothObjectModel3d with the exception
that in surface_normals_object_model_3dsurface_normals_object_model_3dSurfaceNormalsObjectModel3dsurface_normals_object_model_3dSurfaceNormalsObjectModel3dSurfaceNormalsObjectModel3d the 3D points are not
smoothed, i.e., the original 3D points of ObjectModel3DObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3D remain
unchanged. For more details on the MLS as well as a full list and
descriptions of the supported MLS parameters refer to
smooth_object_model_3dsmooth_object_model_3dSmoothObjectModel3dsmooth_object_model_3dSmoothObjectModel3dSmoothObjectModel3d.
Note that for points where the normal vector cannot be estimated, it is
set to the zero vector. This happens, for example, if the 3d object model
contains an identical point more than 'mls_kNN'"mls_kNN""mls_kNN""mls_kNN""mls_kNN""mls_kNN" times.
Note that if a 3D object model is no longer needed or should be overwritten,
the memory has to be freed first by calling the operator
clear_object_model_3dclear_object_model_3dClearObjectModel3dclear_object_model_3dClearObjectModel3dClearObjectModel3d.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on internal data level.
