@kfarr If you have any real world reference images, please share. They would be useful. Thank you

[kfarr]

Here are some examples of arcade construction style or similar: https://en.wikipedia.org/wiki/File:Metz_-_Place_Saint-Louis_-622.jpg Lego style (helpful to see some key elements for low poly) https://www.aliexpress.com/item/1005002870580500.html https://www.alamy.com/arcades-in-the-elegant-buildings-of-the-center-of-milan-italy-image181198422.html https://www.momentousasia.com/arcade-buildings-in-guangdong/ (various pictures in the gallery on the page)

I made a modular asset in Blender using geometry nodes

[kfarr]

This is great @gnansai . I assume this also uses the common atlases? It would be good to save this original blender file with the geometry nodes in the 3dstreet-assets repo?

For now we will need an old-fashioned gltf export. Using this fantastic tool you've created, can you export 4 different arched building variants combined into 1 gltf with 1 material? Length: between 2-7 -- randomized or as you choose Width: 4 for all buildings Height: between 1-4 -- randomized or as you choose

Roof geometry: you choose

Is it possible to vary the main building color for 2 of them? The other 2 should use the colors that you have already chosen as default.

[gnansai]

@kfarr, It is using same material atlas. I will upload the blender file in in GitHub. yes, we customize the buildings(Length, width and height) as required easily.
we can also change the colors easily.

[gnansai]

If we need new designs on building, we can alter these shapes to get complete new design.

[gnansai]

I have made 4 variations,

[kfarr]

great! these look good to me

These old buildings does not have any details on back and side parts. But arched buildings has details on back and side parts. I can remove the details on back and side parts if needed.

[kfarr]

Let's keep it as you have it already, it looks better to have details all around

[kfarr]

The asset build portion of this ticket is complete, next step is to add support for 3dstreet viewer

[Algorush]

https://github.com/3DStreet/3dstreet/pull/257 made the first PR in the 3DStreet repository to support arcade style buildings. I think that instead of asphalt, tiles around these buildings would look better?

[kfarr]

@Algorush tiles like the sidewalk?

[Algorush]

Yes. Or maybe with a different finish, or a tile with a different texture so that it does not blend into the sidewalk

[kfarr]

ok done! https://github.com/3DStreet/3dstreet/pull/257
