Impressive. I believe he's working on a Doom port.

It may just happen to be doing the same thing, but it looks like a hack of the Mega Drive Duke Nukem 3D port.

Since when does that port support sectors with multiple heights?

sectors with multiple heights

Niiiiiiiiice!!

Why does it look all melty?

Why does it look all melty?

Probably because it lacks of perspective correction, which is one of the bottlenecks in rendering.

Except it does have perspective correction, it's just being computed wrong (looks like not enough precision).

[mo68K]

Looking the video I still think there is no perspective correction, I really think the developer is using some sort of Affine, like you can see in this example: https://youtu.be/RyYEGdGwnFs

And like I said previously, correcting the texture through distance was very heavy for many computers back in the day, because dividing by z.

Why I think it's just Affine without perspective correction is because in the video when clipping Near-Z you can see (Around 10s to 11s) this:

Yeah I highly doubt it's doing any sort of texture mapping. So it's not an affine texture warping thing.
