I mean, seriously! In Fallout 3, if you shoot a brick wall, or something else that's concrete, it makes an actual hole instead of a decal. I'm wanting to know how they did this, without eating memory up.

I'm guessing some kind of tessellation

It's the choice of Steins Gate

I'm almost certain that what you're seeing is decals with bump mapping applied to appear as if they're 3D. I've played both Fallouts, and never seen actual holes being made by bullets.

There's actually 4 Fallout games.
Fallout 1, 2, 3, and then New Vegas.
Fallout 3 and New Vegas are the ones with the "3D" bullet holes.

Huh. Never really noticed that. I'll check it out.


btw, does anyone else just hate the draw distances for Fallout? Always thought messing with the fader slides will fix it but it's not satisfying enough.

Yeah, Fallout 3's drawing distance is a bit iffy. However, I play on Xbox 360, so I wouldn't know. I can see buildings like 50 miles off into the distance.
Only question is, WifiKing42, can you see the Washington Monument from Megaton?

"btw, does anyone else just hate the draw distances for Fallout? Always thought messing with the fader slides will fix it but it's not satisfying enough."

don't remember what it was called, but there was a guy on youtube named 'gopher' (i think) who used a mod to fix the draw distance

i'd recommend leaving the draw distance the way it is, though, because whenever he fired from a long distance, npc's didn't even react to the gunshot(even when it hit them) since the npc's weren't programmed for such a long draw distance

Did the mod also fix reactions to gunshots?

well, i think he also installed a mod that was supposed to fix it,

and, although it did work, it was buggy as all hell, sooooo

@vertex

It's more likely that it's a normal map,

because they have more depth.


@OP

Geometric* or topological* not "3D"
because
decals are technically 3D objects with a depth(Z axis) of 0.000000000000000000000000000001

and it's probably one of three things,

Boolean objects

or

Physx

or

Softbody dynamics

Your new face is derp



Also
wouldn't it just be similar to making a 3d crater, but a much smaller scale?

@Star

Holes imply that there is no geometry in the back of the object,

no a crater.


even if it was,

Softbody dynamics or "fractures" === Crater

I meant, more like the bits where bullets hit, but don't penetrate.
Butye.
That isn't really a hole :P

Actually, have you ever played Fallout 3 or Fallout: New Vegas? I'm serious.
There are actual bullet holes, and not decals. It's like a 3D object overlaid on another object, without eating memory, or the textures having a glitchy surface. I'm puzzled on how they did this. And I know it's not a decal, because a decal is a 2D object with a texture that's supposed to look 3D. However, these bullet holes, are actual holes/craters in the concrete surface.

@Fireking

It's 2015

the technology to do that has been around since 2008.


Ever since rayfire became mainstream

@Tested

Bump mapping doesn't work that way...

bump mapping is an illussion, it's fake.


you can tell the difference between the two easily.



@OP

I JUST REMEMBERED!

Displacement mapping + Tesselation!

How could I have forgotten!

Dissplacement allows devs to create the appearence of actual geometry

and add that with sub polygo- err... I mean tesselation, you get the result!
