Hi Elliott, This is a great breakdown and very generous in sharing your process and insights, you came a long way from the vending machine days!
Are you planning on releasing the UE4 project to the public? Or only builds? I'd love to play around with it in the editor if possible!
3Dflow has released 3DF Zephyr 3.2 and the long-awaited Zephyr Free. The free version shares the same technology. Although it cannot process more than 50 pictures, it is still a great start for photogrammetry fans that features no time limits.
So, Zephyr Free can process only up to 50 images, which is still enough for very simple subjects and to play with the first few tutorials. You are also limited to using only one NVIDIA card to speed the processing, and exporting/editing functionalities have been limited too. The customized UV mapping tool and some other tools are not available. The full features comparison is here.
You can find more details on 3DF Zephyr Free and download it here.
As for v3.2 of the full version, it features the following updates:
- Upgraded 3DF Zephyr Lite features
