4 years ago I've been talking to MVTec about this and they said that several customers of them forget to remove these zero points. This makes later processing slow and/or wrong. I think it is a good idea to implement this
Our Genicam producer sets the invalid points to (0,0,0). This means the output object model 3D has many points in (0,0,0), which need to be removed by the user/programmer. For example, in the case of the surface-based matching, the algorithm will slow down and the 3D edge extraction will fail. That means, if we do not remove the invalid points (or the zero's), the user/programmer has to do it by hand (for example using the operator select_points_object_model_3d()). But, this is often forgotten by the user and therefore worsens the performance.
Before we can remove zeros from the SDK we should remove them here.
