Wall representation

[simonsapiel]

What is the correct way to interpret the House modules wall representation? This wasn't clear whilist looking at the source code for house.py. In the source it seems to be generated by the following block

for w in self.new_walls:
      end_points = w.end_points.round().astype('int').tolist()
      if w.name == "Wall":
            self.representation['walls'].append([end_points, ['wall', 1, 1]])
      else:
            self.representation['walls'].append([end_points, ['wall', 2, 1]])

Trying this with a sample data point I got that

house.representation['walls']

returns

[[[[25, 260], [474, 260]], ['wall', 1, 1]],
 [[[474, 260], [474, 680]], ['wall', 1, 1]],
 [[[468, 787], [468, 997]], ['wall', 1, 1]],
 [[[235, 997], [468, 997]], ['wall', 1, 1]],
 [[[25, 1003], [230, 1003]], ['wall', 1, 1]],
 [[[25, 260], [25, 1003]], ['wall', 1, 1]],
 [[[24, 62], [24, 241]], ['wall', 1, 1]],
 [[[474, 62], [474, 241]], ['wall', 1, 1]],
 [[[39, 71], [460, 71]], ['wall', 2, 1]],
 [[[235, 745], [235, 997]], ['wall', 1, 1]],
 [[[235, 745], [400, 745]], ['wall', 1, 1]],
 [[[40, 745], [230, 745]], ['wall', 1, 1]],
 [[[411, 691], [411, 776]], ['wall', 1, 1]],
 [[[411, 776], [477, 776]], ['wall', 1, 1]],
 [[[477, 691], [477, 776]], ['wall', 1, 1]],
 [[[411, 691], [477, 691]], ['wall', 1, 1]]]

so the question is that should I interpret the first two lists as (xmin, ymin), (xmax, ymax)?
