Hi together,

I'm trying to create a transformer that processes point cloud data from a LAS file. To do so, I'm modifying the CenterOfMassCalculator_Python example.

How can I access the point cloud data? The feature.hasGeometry() attribute is true, but feature.getGeometry() returns None.

Code:

def input(self, feature):
   self.logger.logMessageString("--- input() ---")
   self.logger.logMessageString("  Feature type (fme):   " + feature
   self.logger.logMessageString("  hasGeometry (fme):    " + str(feature.hasGeometry()), fmeobjects.FME_INFORM)
   if feature.getGeometry() is None:
     self.logger.logMessageString("  Geometry is none")

Output:

--- input() ---
  Feature type (fme):   LAS
  hasGeometry (fme):    True
  Geometry is none
