Sketchfab 3D Scan Challenge: A Square of Ground

Back to overview

Help us build a patchwork of 3D scans!

For this month’s scan challenge we want you crop out a small square of ground from your part of the world and share it with the rest of the 3D community. It might be your bedroom floor or an ancient mosaic; the leaves on a forest floor or the cobblestones from the center of town – anything unique to your neighborhood

3rd place – Roman Amphora by VaLiuM

It sounds deceptively simple but there’s plenty of room for creativity. Here’s the kind of thing we’re aiming to create:

As an extra bonus, for month’s 3D scanning challenge we’ve teamed up with 3D Flow to offer some amazing scan software as prizes for the top 3 entries. If you’ve never tried photogrammetry before, now’s your chance – just grab a copy of 3DF Zephyr Free, load in 50 images and away you go! Here’s what they have to say about the challenge:

A simple yet challenging challenge! It will require a balance of technique and originality. It is also a great way to use the Free version of Zephyr at its full potential. You don’t need a high number of photos and we are sure the entries will be clever and inventive.

We are very curious and excited to see what the Sketchfab community creates in this unique challenge.

To make it extra easy to get started with 3DF Zephyr, 3D Flow have made these handy video guides:
