It was while making the simplest model in Blender that the lion kingdom remembered how a 160x200 wireframe of the same thing was about the most complicated 3D graphics a Commodore 64 could draw in a reasonable amount of time.
With much experience, it's now obvious how dedicating memory to lookup tables & using fixed point math could have greatly accelerated it. Could there be any point in writing optimized 3D drawing routines for a Commodore 64 now?

Lions long viewed the neighborhoods bordering the office park as the primest locations.  New construction is always the cheapest time in a house's lifetime.  The houses being

 Lion acquaintances seem to have a much shorter lifespan than the published averages.  55-65 seems to be the norm.  Maybe life expectancy is a camel like inflation.  Die by 60 or make it through the great filter & hit 100.   ---------------------------------------------------- Ongoing struggles with Xfinity/Comca$t convinced lions they're now better off renting the XFI gateway than attempting to use a 3rd party modem.  It wasn't this way in 2016 when activating a 3rd party modem was straightforward.  That modem lasted until 2022 but seemed to not survive the migration to a monopoly.  In 2016, AT&T was a viable alternative.  By 2022, Commie was the only option. 3rd party modems are no longer supported via online activation.  It's not clear why the app provides an option to activate a 3rd party modem that merely redirects to the xfi gateway activation & fails when it tries to configure the gateway.  The modem goes into walled garden mode where you get DHCP, DNS, b

 Finally watched Creepshow, 40 years after rereading the comic book many times by flashlight. The highlight visually might have been the now vintage Apple II which was cutting edge in those days. Nothing utterly terrifying.  Better writing than anything current.  Only slightly deviates from the comic book. The highlight emotionally might have been when after feeding his wife to the warewolf, the now liberated man sits down to doing anything he wants.  The big deviation was the warewolf escaping in the end, while the comic book kept him trapped underwater. The zombies might have been easier on the eyes than the single women. The original comic book is now on archive.org with a 1 hour free trial.  With a 4k monitor, all you need to do is screencap it while turning the pages.  The raw images are very high res but a 4k screencap is still higher than any animal would actually read it in. Helas, the center page crease is cropped off. There's enough in a 2850x1890 screen cap to remember w
