Technical Scuba Diving
Background The UB88 team first located and dove the UB88 sub in 2003. They did multiple dives on the wreck and produced both still pictures and videos. At some point, Gary Fabian took frames from the videos shot by John Walker and created a photo mosaic of the wreck: UB88 Sub Photo Mosaic (Copyright 2007 [...]
Background When I first started diving the UB88, I was also starting to investigate and learn photogrammetry. At the time (about a year ago), I thought "wow, building a model of the UB88 would be a cool project." I've been posting updates as I've been working on the project over the past year. Doing a [...]
Background More than any other photogrammetry project, getting a complete and good model of the stern section of the UB-88 has vexed me. It has been very frustrating and my first attempt failed. Below is a screenshot of the model I made in November 2020 that was only able to resolve the starboard side: Starboard [...]
Background In the ongoing project of building a complete, detailed photogrammetry model of the UB-88, Drew Wilson and I went back with Ray Arntz on the Sundiver for two more dives. On my previous dive, I completed the port and starboard hulls to complete the front half of the model. My goal on these two [...]
Background It has been a long time since I dove the UB-88 and I had definitely missed it. I think it is one of the coolest wrecks in Southern California. My previous dive on the UB88 was December 10, 2020 and the visibility was soooo bad at depth that Justin and I couldn't even find [...]
Summary: not quite a "wasted" dive but I also didn't get the results I wanted. I had a feeling that the "ghost net" at the stern of the ship would be a tough one to build a model for. There are quite a few complications like the fact that it isn't a solid surface and [...]
Intro A few days ago I posted about my latest dives on the UB88 with the goal of building a complete photogrammetry model in high resolution. The second objective for the first dive of the day was to finish filling in the "gaps" on the conning tower and to get some better pictures of the [...]
Intro/Background I've been learning photogrammetry skills and software. I still need to publish my model of the TBM Avenger but that is going to take more work. In the meantime, I was able to conduct my 3rd and 4th dive on the UB88 this week with the express purpose of working on the 3D model. [...]
Intro / Background After diving the UB88 wreck a number of times and also starting to delve into photogrammetry, I decided to combine both of these into a rather large project: Build a realistic 3D Photogrammetry model of the entire UB88 wreck. This project represents a number of challenges -- starting with the fact that [...]
In my final post on the UB-88, I thought it would fun, unique, and interesting to post before & after pictures of the UB-88. I've dug up photos from the excellent http://ub88.org website and a few other places of the UB-88 prior to sinking and then I've taken quite a few pictures of the wreck [...]
