it's simple build engine trick, if you open build engine, you will see that mirror is actually a large room, that redraw map that before mirror and put it in buffer, if mirror is not enough to put all sectors you will saw HoM effect, if you destroy the mirror, room instantly collapse and you again see HoM because there is nothing to draw. Btw this is old DN3d version, that kill you instantly in a void space, because there no vertical point to stay, it will fixed later, but simply remain old 'height' stat within void space. You won't die after mirror collapse because there an actually a room with floor and ceiling (but in the same point, so for the game nothing to draw there and you got HoM) *HoM -Hall of Mirror effect, actually game engine calculate distance, and draw a texture and save it in buffer, to avoid constant overflow, there always a drawbox, for 'visible area', this is used mostly in a modern games too, so if players collapse with surface, and there no texture or game cannot draw texture beneath it (void space), they simply remain to draw latest what is in the memory, so you see that weird repeating textures, and etc.
That's some great Build engine trivia. I thought it was going to be a simple 'mirrored room' on the other side of the mirror hardcoded to pull it off. But it's actually the engine redrawing the map through itself for mirrors. The way the uploader could walk around on the other side and see enemies they haven't fought yet was cool. Let alone how it stops as the mirror breaks. Good engine design given the time the game was made.
A common but demanding way to fake "reflections" in games. They often try not to have to re-render another entire room flipped on the other side to get a "reflection" effect these days, lol. Not a glitch though, working as intended ;)
There's another way. If you have a jetpack, go up to the mirror, repeatedly press the buttons to activate it, you should make it to the other side. That's actually how I found it.
Those people on the bottom don't know that it is on original build engine, it uses viewportals or something similar i'm pretty sure to draw it in a separate sector so it looks like a mirrror
I wonder if there's a way to take advantage of this in the Build engine? Either have a sprite/character show up inside the mirror when the player looks in it for a horror effect, maybe even have an enemy trapped on the other side of the mirror... Or, to have the mirror show the location of a hidden door - the player can see something in the mirror reflection that they don't see in the "real world", giving them a hint to the secret's location
Playing with keyboard only, using a big screen, filming directly FROM screen..... that's the real deal, ladies and gentlemen. :D That reminds me to 1997, we started the same way.

Runs more smooth than i thought

I'm playing this via eDuke32 on my 3DS, and _all_ the mirrors have this "HOM" effect. There any way you know of that I can fix it...?
If the mirror is broke it should get its ass up and look for a job.

My dude here recoding a gaming video in 2011 like it was 1997.

Saw a newer video explaining this recently. I wondered where the inspiration came from…now I know!

The Matrix Explained's videos about Mirrors brought me here lol

Yes a glitch though, working as intended ;)
So
Doom my house inspired from this
What engine is this? on what system? In the original build engine this would be impossible.
algorithm
It's not a glitch, you just went out of bounds.
I always called that bizzaro mirror world cause it's whack
great!
Are you playing that on a monitor or a toaster?
