Grzegorz Baran was experimenting with 3d materials recently and decided to try some scanning workflow. The great thing is that he actually documented the whole process and made a short video out of it. This is a nice example of how to capture a non-flat object’s surface.
I wanted to show the way I build low poly for non-planar object and I picked a tree trunk as it seems to be a good example.
I also tried another trick – forced mesh density to hold more vertex color data for baking, but waiting for confirmation from Agisoft it makes sense.
I am still testing part when I combine baked height map with bent normal based one. Works very well but as I haven’t tested it on really extreme and broken surface yet so I am still waiting before I update that section in my tutorial.
If you’re interested to learn more about the technique, do make sure to read the amazing workflow overview from Grzegorz Baran.
