3D model exporting is coming to Trimensional v1.02. For many 3D artists and 3D printing enthusiasts, this is the feature that turns Trimensional from an interesting toy into a useful tool, so the plan is (and always has been) to make exporting available to these advanced users as an in-app purchase for a few bucks. (Note that this is the only feature I ever intend to charge extra for, all other improvements will come free of charge.)
Based on feedback so far, OBJ is a format that would work for a lot of people. If that’s not the case for you, please let me know in the comments. As pictured above, I have some example output here (untextured at the moment) if anyone would like to test it out or get a feel for the resolution or how noisy the raw data is: http://www.trimensional.com/models/Trimensional_15.obj.zip
Any reactions at all are useful to me in building the 3D model exporting feature, so feel free to post any thoughts about whether this output suits your needs. If I understand correctly, the 3D printing folks need airtight models. Boxing in the back of the model is one approach — is there something better?
Thanks, and I look forward to a constructive discussion.
