Technical Scuba Diving
Background I held my first photogrammetry class between Friday, Jan 20th through Sunday, Jan 22nd. This the first time I held the workshop and the results were very good given the conditions we had for the dive day on Saturday, Jan 21st. After a day of lecture and building a model on land, we dove [...]
Intro The "Butterfly Effect" is part of chaos theory in physics. The theory is that a small change in one state can result in large differences in a later state. The prototypical example is that a butterfly flapping its wings can result in a tornado. I ran into a "Butterfly Effect" between building the model [...]
Summary I conducted Dive #4 for my Yukon photogrammetry project on Sunday, 6 November. The model is now close to 5,000 photos. I spent all week working on the model build process. I went down a lot of rabbit holes and my computers were working overtime. I'm definitely pushing the limits for the current hardware [...]
I had another dive on the Yukon and had planned on finishing the front of the wreck, starting the bow and starboard side and try to get some of the starboard edge done. The starboard edge is probably one of the two hardest tasks for this model. The reason is that currents often flow up [...]
Background This is a report on the results from the second dive in my project to build a photogrammetry model of the Yukon which is about 105 feet deep off Mission Bay, San Diego. The first dive resulted in about the back 30-40% of the stern completed. For this dive, I had planned to map [...]
Background Last year, as part of my learning progress of building photogrammetry models, I decided to build a model of the guns (whose barrels are fake) and a model of the prop (which is also not the real prop) on the HMCS Yukon wreck in San Diego. They were well contained projects and helped me [...]
I won't spend time describing the Yukon wreck since it is probably the most famous wreck in California. I've dived it a number of times and there are a lot of cool features. Probably the most well known and most often photographed are the guns on the forward section of the ship. They are massive. [...]
