Where to find engine code for HL2 source code?

[Stroyed]

I'm gonna get back to editing for source, and i'd like to take a look at all the source code for the game's engine. I know it's on github but I'm talking about the deep stuff like rendering, physics, etc. I saw one file included a header that came from a folder labled engine, so how would I find this folder or the code that I'm looking for? I know hl1 had it but there's the possibility they simply didnt release it.

Now that I think about it, I probably can't find the physics code because it mostly belongs to havok, but whatabout rendering? That's my mian focus.

The engine code has never been publicly released. They only include interface headers under src/public/ so you can code against it.

The engine code is only available to Source Licencees.

Source engine licenses are free. If you want to sell it commercially though, you have to pay fees to havok and rad.

That only applies to the SDK, where you use the closed-source engine binaries from the SDK base.

Developers have been able to license the engine from Valve, although it's under NDA, so I have no idea what parts of the code they actually get.
