First time photogrammetry - Difference between OBJ and STL
Hey Folks,
yesterday i tried photogrammetry for the first time to 3d-scan a part of a tabletop miniature, using the free version of 3DF Zephyr with the 50 images limit. The pictures were taken with an iPhone 13 Pro Max on a semi-sunny cloudy day from varying angles, here is an example picture:
(Is there any way to make the pictures smaller in a reddit post?:D)
3df Zephyr was able to use all 50 uploaded pictures and created the following OBJ-file, which does look very good in my opinion:
After importing the OBJ into Blender, the Mesh actually seems to look like this:
This outcome has shocked me a bit. Does the OBJ only look this good because it uses the photos to mimic the surface while actually not being that detailled?
What can i do to improve the outcome? Am i missing something?
Thanks in advance, feel free to ask any questions. Of course i can share the complete 50-photo-set if anyone has a better solution to turn them into a sufficient STL.
