So for something absolutly horrible and a prime example of 3d render art being poorly used to promote horrible and inhuman architecture, here's a prime example. NEOM or " The Line" (or as former president Trump would probably put it: Build the Wall.) by Saudi Arabia's prince Bin Salman.
Jezus whept what a monstrosity
The Line – due to be just 200 metres wide – will make Neom world’s most liveable city ‘by far’, officials claim
www.theguardian.com
Brings to mind 40k's hive cities or Mega city one from Dredd. And ofcourse its being sold with fancy renders as this "totally neccesairy utopian sustainable 100% renewable ai technology green insert buzzword here where everyone inside will be happy and fullfilled"
yeah good luck with that with 0 human scale, 0 fresh water supply to maintain all that greenery, 0 relation to its natural and historical context, absurdy large liminal quality and uni-directionalism( something we totally didn't try in every other sort of modernist,brutalist top-down central planned "utopian" experiment in the 60's ramped up to 9000), not to mention the ridiculous levels of entropic decay and maintainance that this will require and it all being part of a very authoritarian religious sekte government that will monitor your (and your gay or just female friend's) every move in a very confined enclosed space with massive AI surveillance.
though I suppose they can always use it to place their increasing number of kafala's...
