Distance to main entrance

Fig. 40 Distance to Main Entrance

Pseudo code

Distance_to_main_entrance_field.py

Input: voxelized_envelope.csv (low and high res), points of main street and public transport

1. Import Meshes
2. Import Lattice and points of main street and public transport
3. Compute from each voxel the average distance to the main street and public transport
4. Choose the voxel with the minimum distance as the main entrance
5. Retrieve the neighbour voxels of the main entrance
6. Set the value of the horizontal neighbours to 1 and the vertical neighbours to 2
7. For each neighbour:
      Find the neighbours and add 1 (horizontal) or 2 (vertical) to its value, when it does not have a value yet
8. Convert the values into values between 0 and 1
9. Construct the field (lowres)
10. Interpolate the lowres field to highres

Output: Distance to main entrance field (low and high res)
