for item in chunk.markers:
   if item.position == None:
      continue
   v = item.position
   v.size = 4
   v.w = 1
   if not chunk.transform:
      chunk.transform.matrix = Metashape.Matrix.Diag( (1,1,1,1) )
   T = chunk.transform.matrix
   v_t = T * v
   v_t.size = 3
   proj = chunk.crs
   v_out = proj.project(v_t)
