question about ps1 games model ripping

I'm very new to this all and I'm trying to find a website that is good for beginners but I'm having no luck where to start ,
I want to view the models in parasite eve 1 and 2 in a model viewer but have no clue what software I need to use or what model viewer to use , I tried looking for some model viewers but I got a crappy virus site.

has anyone here ever ripped and viewed the 3d models from both parasite eve games ?
is the ripping and viewing method different for everyone ps1 game ?

any help would be greatly appreciated , even a shove in the right direction.
