Summary:

I wanted to test everything that is possible with a smartphone on this skull and the result really surprised me. While mountain biking in the forest I found this beautiful skull of a wild boar, I immediately thought it’s too good to just leave it there. 

So off to a tree stump with him, the light there was almost perfectly diffuse. I think there were about 40-50 photos at the end. I then loaded this photogrammetry 3d model into CaptureReality at home and let the magic begin, the textures were then delighted. For Sketchfab, I reduced the number of triangles again in Blender and for the depth, the ambient occlusion was created as a vertex color and the textures were optimized accordingly in Photoshop.
