    3D File Formats to Archive and Display

    Hello All, DNGs are the standard for archiving photos for posterity, my question is what is the best 3D file format? OBJ? I have noticed that STL and OBJ seem the most common to export from photoscan especially for CRM professionals however I find that those formats are not the easiest to share/display, especially loading online. I have used three.js in the past to display models and those developers recommend using gLTF format because of its quick load time and efficiency, hence the nickname "jpeg of 3d". Any thoughts here? PDF's are easy to share but I know they are a horribly lossy file format... P.S. On this form I found a OBJ/Collada>gLTF converter https://groups.google.com/forum/#!topic/cesium-dev/0tzql9s-e6M .

    Problems with Flat Runs on Pottery

    Ozbigben, I am aware of the issue getting good tie points on the edges of more 2d subjects. Do you have any tips for getting more good look angles on the edges, or getting more of the whole sherd in focus? I know that the recommended f stop should be no higher than f11 from CHI. I have exceeded that limit occasionally after talking with Charles Walbridge from the MIA who is active on this forum. I have been shooting on a clean background and then flipping the object and getting a few circuits on either side, I'll post some screen caps in a bit.

    Problems with Flat Runs on Pottery

    Hi All! Longtime lurker here, I AM having trouble getting Photoscan (regular licence) to recognize both sides of a pottery fragment. I am getting a lot of holes on the sides and the bottom isn't being built. Unfortunately I don't scale bars which I know would help. I attended the Sept 2016 photogrammetry training with CHI in San Francisco. Since graduating college in 2017 I have continued to model but mostly on objects in the round or completely flat and immovable like petroglyphs. I know I need different camera calibration sets and blank shots for building the masks. Any help would be appreciated. Jack
