I should stop while this source file is exactly 1024 lines long. Alas, probably won't be, still quite some fbx stuffs to implement.

...my own grandmother did not end up in Siberia only because by the time they rounded up her whole family and loaded them up into cattle wagons, she was away at her friend's house.

...now of course, in USSR times the Soviets conveniently forgot that they themselves have forcibly deported ~130 thousand Lithuanians to Siberia (https://en.wikipedia.org/wiki/Soviet_deportations_from_Lithuania). "Gee I wonder how one would build railroads and gas pipelines far out in Siberia?" -- through 20th century slavery, more or less.

Some of Soviet times brutalist monuments are actually impressive. Here's one close to where I live (there's a tiny human for scale). This was built in 1984 near a fortress where about 45 thousand (!) Jewish people were killed during WWII.

Something I noticed while occasionally looking at https://www.pouet.net/ : we are entering a time when some demosceners are literally dying :( Over past few years, there's been quite some "XYZ has passed away" messages... On some level, it makes sense and is expected, but still is something "new" that the demoscene has to deal with. :demoscene:

"Doom in Blender VSE" blog post https://aras-p.info/blog/2025/01/17/Doom-in-Blender-VSE/ including the part where I assumed that Python is slow (it is! but not that slow) until I looked at the profiler.

Pace of improvements in Godot :godot: is impressive! https://godotengine.org/article/dev-snapshot-godot-4-4-beta-1/

Also very much like that they have ability to summarize a release in human-understandable language that makes sense. For example Unity :unity: seemingly has lost that ability some years ago, and "so what is new in Unity 6.1?" is actually hard to answer.

So... instead of doing anything useful today... I made Blender VSE timeline run Doom. https://www.youtube.com/watch?v=Y2iDZjteMs8

...ffmpeg has implemented DWA decoder on their own, btw (in 2021, for ffmpeg 4.4). But then ffmpeg bases itself more on EU laws.

...my interest is e.g. tinyexr -- it is another implementation of EXR decoding. But so far it has not implemented DWA out of patent bogeyman.

If, hypothetically, someone implements that, does that still fall under "within the OpenEXR standard"?

What is "open" about OpenEXR if parts of it can not be implemented by 3rd parties?

So here's a question: OpenEXR. There's "open" in the name! But, it contains DWAA/DWAB compression modes. Which, supposedly, are patented. OpenEXR license just says "BSD" but if you look at "PATENTS" file in the repo, it says that Dreamworks allows you to use/modify/distribution "implementation of DreamWorks Lossy Compression within the OpenEXR standard".

Now... what does that mean? Can a different EXR decoding library implement DWA decompression?

34 years ago. Through some miraculous chain of events, Lithuania broke out of USSR with only this, instead of full-on military intervention. https://en.wikipedia.org/wiki/January_Events

"Viewing Images" blog post by @wolfpld is quite a journey. Lots of good material, and quite some (deserved) rants. https://wolf.nereid.pl/posts/image-viewer/
