Love this! One nit. The homepage says “All of our content is copyright-free. It means, you can use them anywhere you want which includes commercial projects too.” That's not how copyright works. All of these works are copyright. That copyright is what allows the owner of the copyright to place them under a CC0 license. What CC0 really means is "the copyright holder has waived the rights they have under copyright by g…

CC0 is “a tool for relinquishing copyright and releasing material into the public domain”, and the official icon for it says “public domain” [1] mainly created because actual public domain is problematic across different countries, I believe. Actual public domain really is ‘copyright-free’, and it makes sense to describe CC0 as making things ‘copyright-free’ to a general audience that may not be familiar with the subtle intricacies of copyright law. It is true that only the original copyright holder has the authority to release their works into the public domain, but once they’ve done that, copyrights are no longer held, and the work is no longer subject to protection under copyright law.

Earlier quoted context omitted.

Let's say I want to "texturize" an existing brick wall of a building. I make high-quality photos, but then what? How do I create bump maps and so on? Do I need a stereoscopic setup? Do I need polarizing filters or something like that? What software is used?

IF you want to make it high-quality, there is a technic called photogrammetry. You need to take hundreds of photos under same light, without shadow or reflection. Then you create the 3D model of the facade using photogrammetry software like metashape or realitycapture. After you have the 3D model, you need to transfer 3D data to 2D texture. It's called baking. After baking is done you endup with basecolor(diffuse/col…

Thank you, these are great keywords to google.

This does depend on the jurisdiction. In some legal jurisdictions the effect of putting something in the public domain is to assert that no copyright exists in the work. In other jurisdictions that's not legally possible.

Is there any software meant for casual users for displaying and walking around these objects? I'd love to have some sort of VR room with the simplicity of "The Sims" where I could add these, plus perhaps some connections to the rest of the internet. A fake TV that displays the frontpage of HN or a 24-hour Twitch feed. A radio object that can play Spotify streams, with 3D audio enabled.

How is that done? What more than a camera and a computer do you need to create those textures and associated maps?

Substance Designer is a defacto industry standard in procedural texture creation. As of 5.4 UE also has a texture graph editor. They're all node based editors combining a bunch of PCG techniques and patterns to produce textures in parametric, non-destructive way.

Don't know of anything like this, but this is a really good idea! It would be sweet to have a scene and renderer with well-known properties (which could be adjusted to account for style; realistic/toon/dynamic lighting/baked lighting, etc) which could be dropped in to a webpage so that users could mess with it. That way, developers could independently include it and write their own ways of injecting the assets.

The end result being a web widget that is a 3D environment with whatever the developer wants to put in it (with some defaults like "sunny outside", "sun room", "basement", "cave", etc), and drag-and-drop asset selection for users to view the showcased assets in the scene. Could even double as a code-guide, based on your idea of including functioning TV and Radio assets (an example of how to include this functionality into the assets). Overall, just a really great idea!

What is PBR? Not Pabst Blue Ribbon! Here's a brief description from Adobe:

Physically based rendering (PBR), sometimes known as physically based shading (PBS), is a method of shading and rendering that provides a more accurate representation of how light interacts with material properties. Depending on which aspect of the 3D modeling workflow is being discussed, PBS is usually specific to shading concepts while PBR refers to rendering and lighting. Both terms describe the process of representing assets from a physically accurate standpoint.
