GitHub has a built-in 3D file viewer that allows you to get a 360 degree view of your 3D models. This 3D file viewer also gives you an interactive diff experience to compare changes between commits!
I created a quick cube using Microsoft’s 3D Builder. I added it to my repo and pushed it up to GitHub.
There are 3 options for viewing the 3D model.
Solid view
Wireframe view
Surface Angle
And the grand finale, how to view a diff of a 3D Model.
Using the 3D Builder software, I added a cone to the top of the cube. I pushed these changes up to GitHub.
If you look at the diff of the commit (click the commit ID circled in red above), you’ll see the diff viewer. By default it shows you what’s changed. Since I added a cone, the cone is shown in green (for additive).
At the bottom of the image, you’ll find the Revision Slider. Click this link for an interactive 3D diff experience!
In the image below, you’ll see how the cone is added.
