If you share or publish Python scripts they have to be made available compliant to the GNU GPL as well, if they use Blender Python API calls.

Is it actually possible to put constraints on scripts that make calls to an API like this?

ygra• 5 years ago

If I remember correctly that depends a lot on the interpretation of the word linking in the GPL. A lot of the license language only works reliably for C code and expectations around it, and things tend to break down in more dynamic languages.

That seems odd to me. Are they arguing that the API calls themselves are under copyright, and so the GPL applies? That sounds like a similar situation to the Google vs Oracle lawsuit - which ruled that the API usage was fair use.

If I write a Python script which a user can use to interact with Blender, and I share it without sharing a copy of Blender, why does the GPL apply?

Taking this to its conclusion - if I write a Python script on Linux which uses any system APIs, those APIs are also licensed under the GPL. By that reasoning every Python script which runs on Linux must be GPL.

That's obviously not the case - which suggests that maybe the Blender declaration is also unenforceable.

Why link to that old issue instead of just the LICENSE file? https://github.com/vvoovv/blender-osm/blob/dev/LICENSE

app4soft5• 5 years ago

Why link to that old issue instead of just the LICENSE file?

Because until linked issue thread was started there was NO branches with a source and `LICENSE` file — as on 2017 in add-on repo there was only one branch with a single file (`README.md`) without any metnions of GNU GPL licensing.

See this comment[0].

BTW, Only in early 2020 branches with a source and `LICENSE` file was added into repo.[1]

A decade ago or more I played a lot of action quake and I remember when I travelled to Europe how awesome some of the locations would be as levels.

A future fun FPS mod would be to take the output from a project like this and randomly throw you in various small parts of the world for team competitions.

People could play their whole lives and learn every major city’s layout. :)

I can see the headlines already:

It could probably be done with Cesium for Unreal, although I question weather it's a good idea to provide shooter games in real locations. Perhaps a less violent sandbox game would be a better idea.

Shooter games are just paintball wars for the brain.

There is also plugin for Godot Engine[0] and a lot of other frameworks[1] and tools.[2,3]

That's more or less what was done in Overwatch from Blizzard. Each map is based on a real location/city and uses its local architecture, typical layout... (However it's not 1:1 with reality. For example the map Rialto is obviously based on Venice, but you won't recognise any particular street or place).

I'm patiently waiting for a game which lets you play in real-life environments. Like an FPS or racing or sim game that lets me play in my favorite cities, or better yet, my favorite towns.

Doesn't even have to be accurate, although it probably needs to look realistic. Like I really only need the aesthetics, not the specific placement / distance of buildings. As long as I get the "feel" of familiar cities / nature that would be awesome.

Geoguessr is already a popular game, and all you do is travel around a location and guess where it is.

Doesn't the newest flight simulator already do this?

Latest FlightGear already supports OpenStreetMap's OSM Data to be used as scenery source.[0]

Like an FPS or racing or sim game that lets me play in my favorite cities, or better yet, my favorite towns.

In most cases you could convert OSM Data of your town[2] using Blender into scenery for such games, which supports import user created scenery. May be some additional export add-ons for Blender would be required to instal for specific game file formats.

Yes, MSFS uses satellite/aerial imagery and OSM data for buildings:

Yes! The only issue is that it takes a beefy GPU on a PC. Which I guess would happen on most games like this, but it still means it's unplayable for me.
