[done]Reflective floors or ceilings?

Worth any thought? I think it would be a cool effect to add to the 3d floors.

I'm sure the olde ZdoomGL by Kokak could do this (IIRC the first level of Zanzan did it). It did look pretty.

Shouldn't really be harder than stacked sectors. The way to implement it is almost the same.

i trust it would work better than stacked sectors currently do in zdoom?

Stacked sectors are far more stable in GZDoom than in ZDoom. The hardware renderer isn't bothered by the clipping issues and as a result there's far less HOM (although it's still easy to create some.)

Ooh, nice. Reflective floors are always spiffy for various things, like puddles fo water and stuff

Floor mirrors too? Also while we're here, would a new mirror system be possible in GL mode? It's a bit of a pain with having to have a empty space behind each line.

Yeah, there have been plenty of times I've wanted to place a mirror somewhere but without rearranging the level I can't get enough space behind the line to allow it.

GZDoom's mirrors are more stable than ZDoom's because I am performing one additional clipping step that discards all geometry behind the mirror. That means that in many (not all!) cases you don't need any empty space - although having it is still preferred.

Getting rid of this limitation completely isn't really possible. There are some restrictions imposed by the way a level is handled that can't simply be ignored.

This would be cool, i am already thinking of things I could do with it.

I can actually walk around inside the upper area without crashing the game!!! I definetly have to make use of this.

It isn't quite done yet though. (But for technical reasons it won't work for slopes and 3D-floors.)

Ohh prettyness. Is the level of reflectiveness customisable?

/expects a trademarked Graf "of course"

Post by **Graf Zahl** » Sat Nov 19, 2005 16:21

Of course. Anything else wouldn't much sense, would it?

Good news.

I forsee mods with nice shiny marble floors (etc etc).

But you have to be careful. For each plane the entire visible geometry has to be rendered again. If you build some long stairs that can easily create slowdowns.
