3D Warehouse Management: Visualising Stock in 3D

Most warehouse systems show stock as lists and tables. That's fine for finding a product. It's much harder to see the warehouse as a whole: which aisles are full, which are empty, where slow movers are clogging up the best locations.

A 3D view turns location data into something you can look at. Done well, it helps people make better decisions about space and slotting. Done badly, it's a screensaver.

What a useful 3D view shows

• Occupancy. Each bin coloured by how full it is: empty, partly full, full
• Velocity. Bins coloured by how often they're picked, so you can see slow movers in fast zones
• Product search. Type a product and its locations light up
• Age and expiry. Highlight stock nearing expiry or not moved in months
• Exceptions. Locations with open count discrepancies or blocked stock

The point is to answer questions faster than a report would.

Where the data comes from

The 3D view is just a layer on top of your ERP or WMS. It needs:

1. Location geometry. Where each location sits: aisle, rack, level and position
2. Location dimensions. Width, depth and height, or at least capacity
3. Stock by location. Quantity, product and lot from the ERP
4. Movement history for velocity and age

In Odoo, stock.location records include X (corridor), Y (shelves) and Z (height) position fields. Fill these in systematically when you set up locations and you already have most of the geometry. Dimensions and capacity can be added with a small extension. Stock and movement history come from standard tables.

How to build it

A practical stack:

• A small backend endpoint that returns locations with coordinates, capacity and current stock (from Odoo's API or a custom controller)
• A web front end using a 3D library such as three.js to render racks as boxes and colour them by the selected metric
• Click a bin to see its contents, with a link back to the ERP record

Start with simple boxes. Photorealistic models add cost without adding insight.

For big warehouses, render only what's in view, and aggregate to rack level when zoomed out. Thousands of bins render fine in a modern browser if you're sensible about it.

Uses that justify the effort

• Re-slotting. Spot slow movers in golden-zone locations and fast movers buried at the back. See warehouse layout and slotting.
• Space planning. See true free capacity before agreeing to a big inbound order or a new client.
• Training. New staff learn the layout faster.
• Management reviews. A picture of an overflowing zone makes the case for racking faster than a spreadsheet does.

Digital twin, or not?

"Digital twin" usually means the 3D model updates in real time from live data, sometimes from sensors such as RFID readers. That's possible, but most businesses get the value from a near-real-time view refreshed every few minutes. Go real-time only when a specific process needs it.

Getting started

1. Make sure location codes and coordinates are clean in your ERP
2. Build a simple 3D occupancy view for one zone
3. Add velocity colouring
4. Show it to the warehouse team and ask what they'd want to see next

We build 3D warehouse views on top of Odoo as part of our warehouse management work. See also RFID integration with Odoo if you want live location data feeding the model.
