White mystery dots...

[ReZeroX]

Everyone has obviously seen the white dots around G-Mans neck, correct? Well i was just thinking, these remind me of postal 2 and the "body part removal system". The dots could possibly be the line at which a characters head can come off. Im not sure, but that would be very cool if body parts can come off. Just thinkin here...might inspire somone or somthing.

 

[Mr.Reak]

Nah.. I don't think so, it is just a bug, imho. But to get real answer, somebody needs to e-mail Valve about it or wait for HL2 to come out

 

[LoneDeranger]

If anybody is gona loose their head in HL2, it won't be the G-Man. I can guarantee you that

What now Lone?!

DEAR LORD! Now they need a stand in! Wheres Christopher Walken?

usually thats a fragment of modeling. When vertices (little dots that represent a tiny part on the model) don't meet up EXACTLY, sometimes the leave gaps of no model/skin, so you can see through it. The white parts you see are literally the inside of the model, which has no skin.

 

[urseus]

Then surly it would be good skinning to skin a small part of the insides, where the joints are to make it seemless.

They probably will, though even if they dont, i doubt youll be able to see any kind of white lines in game due to characters constant movment.

i guess we will find out in the upcomming days
theres more than one person i would like to decapitate
just to test the engine of course

Polygons are one sided...there is no way to skin the inside of a model. Unless you were dumb enough to model the insides.

The white dots are Gmans collar showing thru. They would be blue dots if he were wearing a blue shirt.

Vertices are actually the edges of a poly, not dots. Its impossible for vertices to "not meet up" (outside of terrible modelling) because the polygons actually share the vertices, like folding a pice of paper down the middle. The fold would be the vertice, and the two halves would be "faces". Vertices arent actually drawn by the engine, only the faces.

Its just an artifact...probably cuz theres no AA to cover it.

Unfortunately, those 'dots' are definitely not a movie compression artifact.

They're gaps in the polygon seams for the G-Man's head and neck. You can see the same on the G-Man's chin as well. Maybe VALVe handles their character heads/facial animations in a seperate program and they get re-attached at a later time. It might even be done programmatically. Maybe it's a skinning artifact. Not really sure, I don't know much about animation, but I've definitely seen this kind of glitch before.

BTW a vertex is a non-rendered point in a 3D space. A face is one triangle formed by 3 verticies. A polygon is two or more triangles formed by at least 4 verticies.

The 'seam' between two triangles can be referred to as the polygon edge. It's quite possible to export a model with the faces/vertices not attached to each other. Though I'm not at all saying VALVe did that in this case.

 

[Wesisapie]

Yeah, i have never done modelling, but due to a little common sense i can safely say it's from an error in the modelling.

"turn on AA to fix it"
no the smartest comment i've ever heard. not even close. AA doesn't "magically" fill gaps, it just smoothens edges. also this isn't a fix, even if it did work, it is just a cover-up.

 

[Demon-Dragon]

Watching the shakey cam video of the whole demonstration again you can notice the same fault. It's harder to see because of the quality but i'm certain it's there.
They have most likely fixed that problem with the model though.

 

[crabcakes66]

Ive noticed it to..but i dont know why people are so worried about.

valve isnt that dumb. its just a demo movie

 

[Guest]

Yeah, for god's sake, this is the 5th thread about this god forsaken problem...just leave it alone...you won't have a problem with it in game (if it's even in the game)...OMG....hee hee hee...have fun doing your mom!

 

[mchammer75040]

ugh

 

[Rabid Llama]

But what if you're playing the game and the G-Man's head flies off and blood sprays everywhere and Alyx has to change her shirt and Gordon has to buy new pants and the aliens take over while they're busy and all because of the G-Man's neck seam?!?!?!?

 

[freddythefrog]

game over?

Well, alyx gets to take her clothes off... all other is irrelevant

But i don't think you'll get to decapitate the g-man. He's too important, and also, it somehow simply doesn't fit in... i donno why, but i don't think its possibel

Best idea for a mod ever.

Right...my stupid "paper" analogy makes no sense...I guess I was tired.

1 thing, a polygon is a face...there is no minimum number of faces needed to define a polygon.

What could have happened, as you point out, is the head was re-attached without (depending on your favorite 3-d package)joining/merging/welding the vertices.
