I could write 10,000 pages about CGI

short version

Poser for premade stuff ,render stills
real simple animations
poser pro plug for highend app's
poser chatacters a real high polycount 60,000

DAZ Studio for premade stuff ,render stills
real simple animations.
can use something like a plug for highend app's
Studios characters have geo graphting
Studios characters polycount 20,000 made for high end app's

DAZ Studio is free.
both have strong and week points.

zBrush stand alone for stills
make anything you can imagine
plug for high end app's ,animations.

if you get a high end app for animations
it's very complicated takes a lot of time
to make highend animations ya would need a renderfarm and a CGI crew.
