oh the irony. only hundreds of hours? So elsa was made in a week? yep. you sound like you know.
That's just the base element, depending on where you draw the line on what constitutes Elsa, costumes, customized lighting, hair physics, makeup.
There is absolutely no less work involved in the creation of Cgi movies vs prop movies.
Props are nice to blow up or light on fire, but they generally lack the complex geometry possible in CGI.
In a nutshell, this is what's wrong with the world today.
Actually, CGI tries to emulates the "complex geometry" found in this world either real or imagined, not the other way around. but you knew that, right? You're only actually just kidding here, surely. For example, you clearly will know the "complex geometry" of sunlight / translucency / refraction / reflection and oh, i'm bored now still can't be reliably modelled by cgi.
Notice that tower had mostly flat panels with bumpy protrusions, it'd be very difficult to add complex curvature as in CGI.
You are diminishing what cgi artists do, and yet you know nothing about it..
"bumpy protrustions" - that's clearly the technical term. The artist will state, I'll have some "bumpy protrustions" over here, some more "bumpy protrustions" over here, and some really large "bumpy protrusions" here. Sounds like weird science all over.
By complex curvature, you mean... a sphere, for example a football - something people have been making long before the first resistor ever appeared? That's really complex. Or maybe, you mean weird shapes with curves, just like what Raphael, Leonardo and all the other Greats were chiselling out of marble long before you learnt to say "I've just pooed my nappy"? Those shapes the Greats were carving - just imagine the mathematical equations needed to define them. Wow, MUCH COMPLEX.
Pro-tip, trying to sound like you know what you're talking about by stating your opinions as fact may work with your 15-year-old friends but just sometimes doesn't work in the big-pant-wearing world. For example, computers can't render "curvature". Only straight lines. a cgi 'sphere' is a high resolution multi-faceted shape, or at best, mathematical equations which approximate curves.
I love that you feel you are the defender of the true faith and have to press this point. I think I've forgotten more about 3d workflows than you appear to know.
Do tell me oh wise "Zoltar Speaks" (inserts 10c), what else do i know nothing about?
