Can microscopic structures be created in ZDoom maps?

[printz]

I know I posted a question about floating-point support before, and one of the reasons was this very thing. The answer was that no, Doom is still fixed-point. But anyway, I think that 1/65536, which is the fixed-point quantum, still qualifies as microscopic. So I'm wondering if it's possible to squeeze otherwise gigantic 65536x65536x65536 maps (such as entire Doom IWADs) within 1-unit size cubes. It would make for some very nice easter-egg / bonus maps for highly curious players.

Correct me if I'm wrong, but I think that sector height is still fixed point in integers.

[printz]

You mean fixed point (that is, multiples of 1/1665536 units) or actual integers (multiples of one)?

[Sodaholic]

Gah, crap. I meant integers.

I've tried doing something similar to this before, and I ran into a few problems. Namely, the use distance was the same, so it looked like you were opening doors from a mile away.

[Gez]

Even if technically possible, it is going to be a complete mess for the nodebuilder.

[Graf Zahl]

It's not possible. Since each UDMF map needs to be nodebuilt with ZDBSP its limits apply and it treats 5/65536 as the smallest representable value when it comes to vertex distances.

[Demolisher]

Sooo... 65536x65536x65536 maps within 8-unit size cubes.

That's still tiny.

[Sodaholic]

So, is it actually possible to change the use distance? It's pretty absurd having Doomguy being able to open doors and press switches that are literally like 20 feet from him. (I'm talking about reduced scale here, my 1/4 scale mod kinda sucked because of this.)

And, taken in the other direction, it would allow large players to have a longer reach.

Going for Congestion 1 jokewad eh?

You should check whether this has been suggested before, and if not, make the query yourself.

[Xaser]

Hmm, this indeed makes me wonder how far one would be able to shrink a tiny piece of easter egg geometry before the nodebuilder starts shitting a brick. Micro-E1M1 statuette, anyone?

[printz]

Are the available nodebuilders the ones to shit the brick first, or is it mathematically impossible to make nodes on detail too fine, even before reaching the 5/65536 hard-limit Graf Zahl mentioned? If it's the former, then someone with a hobby and plenty of time may program a more comprehensive utility for this effect.

Too bad that microstructures have no real use in ZDoom, unlike in real life.

[Edward-san]

I think it's possible (change 65536 with one of its multiples, say for example 10*65536), but you need to multiply all the length unities with 10. Too much work with little gain IMHO.
