Silly Doom trivia question for anyone who ISN'T following my tumblr:
So someone implied Doom (1993) rendered triangles. I pointed out that it does not, it's solely rendering line strips for walls and sprites, and weird horizontal strips for floors.
HOWEVER: I was wrong. Doom DOES render triangles. But where does it render them? Because it's only one specific place.
(Outside of level designers making triangular rooms. That doesn't count)

That is, anyone who doesn't follow my tumblr and also isn't @fabinou or John Carmack

@kemayo close! But it's an arrow, not a triangle
David Lynch
@foone isn’t there a triangle that represents the player in the map view? (I’m going on very sketchy memories here.)

@nil correct!
nil :demisexual_flag:
@foone the triangles for things when you type iddt twice?

@razze close! But normally there are no triangles in the map view: just sectors and the player arrow (which isn't a triangle)
razze
@foone the map view?

Since a few people have gotten it:
It's the automap, but only if you use the IDDT cheat code. That enables drawing triangles around objects/enemies.

@raptor85 yeah! there's no need for triangles if you're drawing with vertical or horizontal strips, which is how Doom does all the main rendering. The only place it needs triangles is on the automap
Raptor :gamedev:
@foone as someone who's current project's renderer ended up way more doom-like than originally intended, you're talking about the map right? Triangle rasterization wouldn't even be useful in an engine drawing with vertical strips, though i suppose technically possible if you drew it like a sprite. Could also almost count floor slopes as triangle rasterization but the vanilla engine doesn't support that.
