Tinker Tuesday for December 16, 2025

This thread is for anyone working on personal projects to share their progress, and hold themselves somewhat accountable to a group of peers.

Post your project, your progress from last week, and what you hope to accomplish this week.

If you want to be pinged with a reminder asking about your project, let me know, and I'll harass you each week until you cancel the service

Made good progress actually. Got effectively all of the Unreal systems I'm in contact with under control. Was unhappy with the default 1cm scale unit, so I rewrote all my code to work off of scalar and vector objects that automatically respect a flexible scale factor. Then I decided not to actually use it because too many Unreal systems rely on the default scale. Then I immediately regrettet not using it because as it turns out, double-precision coordinates do not imply double-precision rendering (obviously, in retrospect), and my large, distant objects had all kinds of rendering artifacts. I really don't feel I need the short-range precision that comes with the default 1cm scale - not by many orders of magnitude. I'd be happy to trade a lot of it away for better long-range precision (so long as things immediately in front of the camera don't start to jitter), but that comes with many unknown unknowns. I don't know what all will break, or rather will not work as intended when I implement it, when the scaling is off. So I'm putting the whole scaling and large-objects-visible-at-long-ranges matter on hold for now; better to avoid that technical rabbit hole. It's taken too many months from me in the past.

Overall feelsgoodman.jpg. I can plan things and just do them. Turns out ChatGPT is an adequate substitute for lackluster documentation.
