The Questions We Ask Before We Ever Turn On a 3D Scanner

By the time we scanned The Hive, the 20,000 square foot garden centre we built for the Earl of Suffolk's estate, we had already spent longer planning the scan than most people would expect. Turning on a scanner is the easy part. Getting a useful result out of it depends entirely on questions we ask before that happens.

The first question is always what the scan is actually for. A scan destined for a photoreal render needs dense coverage of every surface a camera might land on. A scan destined for a floor plan or a planning document needs accurate dimensions far more than it needs visual detail. Treating every scan as if it needs maximum density everywhere wastes hours of capture and days of processing on detail nobody will ever see.

The second question is access and light. Garden centres, unlike a controlled studio, change light through the day and are full of moving stock, staff, and customers. We map out a capture route in advance that avoids direct sun hitting glass at the wrong angle, and we agree a window with the client, usually early morning, when foot traffic and light are both at their calmest.

The third question, and the one clients are least prepared for, is what happens to items that will not be there when the render ships. A garden centre's plant stock turns over constantly. We agree upfront which fixed elements, the buildings, the shelving, the layout, need scanning in full detail, and which changeable elements, seasonal stock, temporary signage, we will model separately so the render still looks right in a different month.

Getting these three questions answered before a single scan happens is what turns a day of capture into a usable asset, rather than a folder of point cloud data nobody quite knows what to do with. The scanning itself rarely goes wrong. The planning beforehand is where a project either sets itself up to succeed or spends the following month firefighting gaps nobody noticed on site.
