How do people port models?

[Rixil]

Hey, recently on websites like garrysmod.org or fpsbanana i have seen many people porting models from other games into Source games, notably garry's mod.

I didn't get any help at Facepunch forums, cause everyone there is a bunch of assholes, so i was wondering if perhaps people here might enlighten me?

They use API (DirectX, OpenGL, etc.) rippers.

Alright, thanks. Is there any link to one of them? I got the HL2 compiler now i just need a site that is safe to download the thing from and port a futurama character from UT2004 to Gmod.
