It's not about how easy it is, or how many ways there are to do the thing. The point of a 3d scan is to reproduce the facts of the object being scanned: there's this surface at this position with this normal, another one there with these properties, etc. Choices to be made might trade accuracy for less cost (in time and/or money), but those choices don't change the fact that the scan's purpose and value rest in the facts being recorded. It's like the quake fast inverse square root vs the pedestrian n => 1/sqrt(n), the skill in writing fast inverse square root doesn't imbue the result of its evaluation with any of that.

WRT your second paragraph, I'm not sure I understand. How could there be a copyright violation on something that can't be copyrighted?

Ok, if the facts that are used to make a phone directory can't be copyrighted, then why would the facts that are used to make a 3D scan be copyrightable?

I mean, nobody other than the scanner chose or wrote down all those numbers. The creator of the object made an object. Seems like the same distinction to me as a house vs. its phone number and address which locate it.

I'm not quite following wrt the phone book/ house / phone number / address.

Per wikipedia[1] copywrite is on "the original expression of an idea in the form of a creative work".

The bust is that expression, the scan is a copy of that and therefore subject to the same copyright as the bust itself (in this case, no copyright).

For a house, I suppose the original expression would be the architect's plans, the house itself is a performance of that expression (when you commission plans from architects part of the terms are under what conditions you can build according to those plans; where I'm from standard terms are for a single performance, at the site the plans were originally commissioned for).

A photo of the house (partially) copies the house which (partially) copies the plans, therefore the photo is subject to the same copyright as the plans (depending on what the jurisdiction says about photos of things in public space). However, a photo may also contain creative expression in the framing, lighting, etc, and is therefore also subject to its own copyright. So to distribute the photo you need permission to distribute this original expression, plus permission to distribute the underlying expression. The more concrete example of this is with models -- advertisers need permission from both the photographer and the model being depicted in the photograph.

There's no creative expression in a phone number or an address, so copyright doesn't apply. Even if there were, there are usually exceptions to enable interoperation (AFAIK Oracle including a poem as part of the database wire protocol[2] hasn't been tested in court, but it's basically the same thing as in Sega vs Accolade[3], which didn't go well for Sega).

I hope something in there answered your question.

Again I'm not a lawyer, this is my understanding from my past work both as a photographer in my own name (i.e. I own the copyrights) and doing work-for-hire. And more recently contracting with architects and arguing over the terms.
