Advanced Mortgage Calculator

After my first post about a simpler mortgage calculator now I developed a more advanced one, especially designed to compare different mortgages, and calculate which one lets you pay less interest over time.

The app can be found here

Compared to the last tool, which just calculated the total interests and the installment amount, this app offers these other features:

  • charts of the installments over time
  • capability to add different types of events:
    • interest rate change
    • time renegotiation
    • amortization on time
    • amortization on installment amount

Adding events makes this tool extremely versatile and allows for simulating complex scenarios. You can compare a 10 year mortgage with a 20 years one in which you reduce the time amortizations with annual cash deposits, or a combination of different interest rates which may happen in some situations. The charts are updated automatically, and there is a comparison chart to make it easy to compare the two mortgages over time, focusing on the interest amount paid.

Plani3D – Planimetry/map to 3D model

In the last days I’ve been working on this helper software to make it easy to turn a planimetry of a house into a simple 3D model to make it easy to visualize it or any modification you would want to make.

The functionalities are extremely limited and it may be buggy – it was only coded to suit my specific needs.

So far it lets you:

  • Load a custom image (planimetry, map)
  • Define a scale (so the 3d model will have the right measures)
  • Draw 3 types of entity with the mouse
    • Walls
    • Windows
    • Doors
  • Change thickness of walls
  • Generate the 3D model
    • saving the link will let you see it in the future too, the model gets encoded in the url (which could get veeery big)
  • Export the generated model as a GTLF file

Note: no deletion of added walls is possible at this time. Not even editing the generated model. It’s more a rapid prototype tool, doesn’t let you make things precisely.

The project can be tested here.
