Golem and the Brethen Demoned actually looked pretty damn good in LOTR ... also alot of the beasties did too.
Like the Ogre in the first film, and there are several Orc's that were and were shown close up that I bet a good few people missed.
I only tweaked onto them the 3rd watch of the film cause the lighting was slightly off when the camera changed position.
You have to admit getting 10,000 people into Orc makeup though for simply scenes would've been a nightmare and a half.
But most of them weren't actually CG in the traditional sense, infact the armies were done quite cleverly.
What they did was create the terrain and then they scanned in each of the orcs that you see in makeup in one of the first scenes.
They have them doing actions ... then they generated that onto the computer, then they combined that with a large number of actual made up orcs.
so although there was only around 3,000 extra's they had tags to keep the position, the cameras position was then fed to the camera - so you have alot of real orcs and even more fake orcs ... but most people who had to spot who was real and who was fake was unable to
Golems lighting was off throughout most of the movie which made him stand out a little ... needed to be softer with more GI Rays if you ask me - however when he's in the woods with all of the shadows and such, he looks blood realistic even with the skin defects looking pretty good.
And as i said the Brethen Demon was just awesome when gandolf is fighting him
, although his is a mythical creature you couldn't really do in Real Life very easily ... the whole look, lighting and even the flames & smoke were pretty much spot on and just flowed without you feeling there was any problem with it.
I think that Lucas has gone insane with CG in SW1 & 2 and most of 1 looks very fake and annoying, but in 2 it was alot better.
The animation were still very ropey...
the most major problem with CG is a) details, static models that aren't really affected by sweat/heat/cold/etc... tend to look fake and b)lighting
personally i think Blizzards CG department should do more of the Film Level CG work - i mean if you've ever played Diablo2/Warcraft3/Starcraft and such you'll have seen how good those guys are. Alot of attention and detail goes into thier work that most other animators just don't bother with.
Shaders are fantastic little things that are now seeping into the entire graphics package industry and quite frankly they are what allow people to create truely realitic stuff because you can program a shader so that it'll create the responses and reacte to the stimulae from within a given graphics scene...
meaning that if you want your model to sweat and for it to affect your characters rendering when they're hot YOU CAN now. You want the oil in the skin to change which can either add alot of anistropic or blur to an oylar-blinn you can now.
it gives you the ability to program your graphical pipelines to make your scenes truely interact with each other on a graphical level rather than a scene level.
