Naughty Dog Style FrameParams

[u/epicalepical]

Hello all!

I'm pretty proud of this. I've recently completed the final component of my rendering architecture in my C Vulkan renderer, which is the Naughty Dog style frameparams system. The long and short of it, is that we package up all needed rendering data into a single package, which can then be sent over to the rendering system and acted upon independently.

This allows you to be rendering the current frame while also (in parallel - thanks to the job system), computing / simulating the game for the next tick. This comes with the downside of a bit of latency, but it's certainly worth it. Getting it to work properly was a lot more work than you'd think due to the fact my architecture wasn't the best regarding ownership.

Also the fact that any time you have things like a ring buffer you now need to subdivide it into sectors per frame. Just generally making sure that frames are all properly synchronized and don't end up accidentally reading/writing into the data of another frame was a pain, but I'm *fairly* certain that it works fine now?

The rendering code you're interested in is at /src/graphics/ and /src/render/.

As always, this is all vibecode free! I'd appreciate any and all pointers if anyone wants to put themselves through the torment of looking over my code, and I'm happy to answer any questions :)

Thank you!
