Why Do We Need Polygons In 3D Video Games? 

i do 3d modeling too, doing it in collage next year :D

Tiedie true, I am making a game using only my own assets, and I am manually shaping cubes/basic shapes in blender into the shape I want, but I am no artist and so I have gone for a low poly design since I just don't have the time/patience/skill to create high poly models.

Yo 3D artist here too.

Its interesting to see you here Tiedie I've been subscribed to you for ages now how have a career in game design one day

A pixel is technically not even a square depending on the screen.

A dot is just how something is appearing to the eye,in a nutshell.

A dot is actually a square. Not a dot.

If you are watching it on Trinitron where each pixel are zig-zag itself, it makes you think, is it a pixel, or square, or dot, or zig-zag RGB, or maybe triangle...

bbarrett726 agreed I want more of these

The more you know

Right falcon got the best topics on this channel

The Bakersman having done this by accident I do not recommend.

Doug demuro fan spotted.

The Bakersman I mix Pepsi and Coca Cola with Caffeinated Coffee, works wonders. Just don't replace Pepsi and Coca Cola with Red Bull...

I've seen people put creamer in coca cola. This doesnt sound too bad.

MegaNocab i agree😂

Actually, UE5 on PS5 don't have limitation on Polygon anymore. They explain all polygon are not limited. So we are in the end games is all about IO now and SSD speed to stream all assets without limited by polygon.

@@mightyhadi6132 For Nanite, yes, but Nanite has the downside of requiring heavy precomputation. It doesn't work so well for deforming meshes (ex: character animations) and it's completely unusable for dynamic topology changes (ex: fracturing an asteroid when you shoot it at precisely the point you shot it).

@@darkengine5931 agree , that's why the new UE 5 2.0 are enabling Tessellation , for deformation . Fortunately PS5 is running at higher clock speed and has high fixed operation .

@@mightyhadi6132 Dynamic tessellation is awesome although I think hypothetically we could do even better with per-pixel displacement with a raytracer... but I think real-time raytracing isn't quite there yet.

We don't have a single game that look close to UE5 demo's lol😂

Khalid Himmo Nah, the actual world is a bit stranger. Wave like voxels moving through 26 dimensions.

ron Like ur mom

Scotty Nguyen's 80s Mullet then u r his brother? jajajaja

Khalid Himmo You should watch the video "Are You a Simulation?" on VSauce3.

+ronindebeatrice Games need more voxels.

Exactly! Those f*ckers can´t be bent, therefore it avoids a whole new level of glitches caused by any other more complex face.

Zenthex TRIIIIIIIIIIIIIIIS are annyoinf to work with

Normally you can work with different shapes in 3D Editors. Then it exports them as triangles, but you are not limited to triangles when working, for example, in 3D Studio Max.

you can use quads for relatively flat shapes for example

Yes sir!

Beautifully said.

He literally just said that as I read this.... Woah.

@@CloroxBleach-oj2rl Carl Jung's Synchronicity theory.

chizzy but i hate math

I like porygons more

*I LIKE TURTLES*

Why do i see you everywhere?

The more polygons on a 3D game the better it looks. For example, Heavy Rain video game.

Clen Vingt-trois it depends on the game. realistic games should look realistic. cartoony games not so much. both still benefit from good lighting.

Merry Christmas

**Triangles**

Yep, triangles. If you're doing it right, it only takes 2 triangles; you'd use a shader to render the curvature.

lol 😂 i can just imagine you absalutely paranoid*Circles are made with sqaures...*

Simon Nitzsche Pollygons are rectangles sometimes. height maps and normal maps help draw circles on flat surfaces to : p

Raymarching can render perfect 3d object

No’ît koxöza.

He says it several times in the video. He even says "sam" at one point instead of "same". I have heard many different accents before but this is new to me.

Lol. He said that.

Tim Sweeney believes we'll have true photorealism with 40 Tflops of GPU power. So in roughly 7-8 years. Realtime fluid physics at a large scale are further out as a standard in games, as it requires enormous amounts of processing. I wouldn't expect the oceans of an Assassin's Creed game, for example, to use realtime fluid physics that rivals real life for another 20 years.

Well technicaly it could be done if the only thing youre doing in the "game" was taking water out off bath

Right? lol!

Martin Boylan at that point you may as well just live in real life

But I can do all those weird things while in the comfort of my home, clean and spotless.

Thanks!

I dunno if it's the best but it sure is cute, also i don't remember seeing him that much in the anime..

the one from gen 1 is pretty cool

+JormungandR - Porygon was never banned, *The* porygon episode was. He's appeared in other episodes of the show, but it's never been a popular Pokemon. It's like saying "Wow.. I don't remember seeing Belsprout in Pokemon.. must have been banned."

For sims

its in the game

To make shitty games like skate 99.99 for skateboard

Because they're still making enough money to stay in business. It's pretty simple.

You do know that's GTA V, and GTA V is based in San Andreas just like GTA San Andreas.

Ron Da Bird you didn't know what I meant. I was talking about the graphics around 2:20

He was saying that the graphics at that point in the video looked similar to the graphics in GTA San Andreas.

Which video ?

nop, san andreas was lower poly count and got worst texture ( except if you use mod ;P) and thatboi hops it's wrong, Gta V is based in southern San Andreas, 2/3 of san andreas map is missing ( San Fierro county and LV)

years ago. There's a reason there's no news about that. There's no real-time application for it, as it's not actually feasible.

Bearded Weirdo TV Thank you. There is an indie game thats out that uses it.

DwayneW1987 Do you recall the name of the indie game?

yea I remember watching tht 6 years ago, but we dont hav the tech yet for everyone, the general consumer, to hav a system tht can play those kind of games. (plus its still too expensive.)

The company is still in good business, and they do use the technology. But they seem to have stopped following the plan to use it in games. www.euclideonholographics.com/ I guess at some point they came to some technical difficulties that they just can't overcome yet.

That is more of a lighting and shadows question though. Also with Blender, it doesn't do anything light related until you hit the switch on one of rendering engines it has, and even there: Blender Internal does only 1 calculation for 1 pixel for X lamps you have in the scene, either if it's lit by it or not(unless you use smoothing then 15 samples is enough). To be honest, games would run with Blender Internal at like 5FPS. Blender Game engine does stuff like a game engine and does more smoke and mirror stuff by predicting where the shadow would be. Cycles is I believe the one you were talking about with that. A lot of ray scattering and... even more of ray scattering. Eevee(coming in 2.8) is kinda like game engine, but it's a mix between raytracing and modern game engines, where it's 99% realtime, but if you look close enough you would still see it losing noise over time every time you stop moving the view around.

QuickscopingFTW Didn't Carmack have a raytracing engine running in game in near real time 20 years ago?

+ronindebeatrice Yeah, but that was like 320x1 raytracing with just 1 simple thing - see which part of the wall/object/whatever's texture it needs to render for that pixel, and the distance. Reason that the height resolution is 1 is beause it does only 1 check for a whole vertical line on the screen, and then draws that whole line based on 3 variables - what texture to use, what part of the texture, and how close it is(how big to draw it). It's maybe a bit more complicated than that(transparency, for example, drawing hand of an enemy and a wall at the same time), but still, same logic applies - non-realtime raytracing with a lot of calculations and Wolfenstein 3D's simple near-realtime raytracing aren't the same thing.

Architector #4 I wasn't thinking Wolfenstein actually, but something much later.

What is it then? Can't think up of any other raytracing thing Carmack did long time ago...

Like dating sims for example

I play them for research.

Gamer dude89 and if you enjoy doing those things witch you can’t do in real life then the main purpose is for enjoyment

Or used for training solders. While we pretend they have no effect on people because it's "just a game". *eats my cake*

I play gta v to go into the nightclub

I typed up a comment for this just now, looked to see if anyone else did already, and now I'm sad.

Better luck next tim

Alpha Morty I was wondering if anyone else has noticed this. In all these videos, most of the time when he says "game" on it's own it comes out as "Gam", but things like "video games" and "gameranx" always sound fine lmao

OSHMKUFAHSA He's talking about the way falcon says "video game".

vidyo gam

Whas it even actually explained why do we need those polygons? Have I missed it? He didin't even shown any alternative...

Why do gamers nowadays cares more about game graphics, rather than gameplay?

Because... there is ni gameplay nowadays?

He did mention an alternative but that alternative is too expensive processing wise, which is rendering 3D models like a voxel image, with algorithms defining a shape.

Jay Co I'm pretty sure that even voxels use polygons. Though I have no idea how you'd create a perfect sphere using a 3D application, but I suppose you'd do something similar to how you create a perfect circle in 2D. That would require an insane number of polygons though, so how does one create a 3D sphere, in a 3D environment, without polygons?

Funny how a sophisticated structure of atoms is asking why it needs atoms to exist.

It isn't that we "need" them to per say, they just do. I won't say "simply" because there is nothing simple about them.

WooferJr that's why I believe in God cause of how amazing we are perfectly structured. :) either that or believe in random lucky chance that we exist only to question our existence.

Those atoms may be virtual and be nothing more than a simulation.

You could argue that it may have already hit it's first plateau. Ultimately the goal is to create a piece of art that is pleasing to look at and conveys the message of the story. Something you can get lost in and forget you're not part of that world. I'd say they hit that level a generation or two ago. It isn't a coincidence that so many games are coming out with less realistic ascetics. It isn't just because it's cheaper (Though I'm sure that helps). It's because the artistic direction has long since become more important than our ability to make something look believable. Mostly because realistic is something we can already do at any level we'd need to. There's a second plateau. One that strives for indistinguishable realism in games. That's an artistic goal all it's own. But if you ask me. Success like that is now just a goal for those pushing the limits for that wow factor. Not something every developer needs to, or even should, strive for. These days it's about what's good for the game. Not so much about what's going to show off the power of the system. Now to undermine myself a bit. I just got done with Evil within 2. Who animated the faces in that game? A Barbie doll sculptor?

Frank Stapleton I never said whether they were good or bad but the technology is in its infancy, it has a long way to go before It hits what many see in sci fi movies

Hardly surprisingly considering that was released 25 years ago. I mean it's pretty obvious VR is still in it's infancy, the technology has only just begun and has a lot of restrictions still despite some fun games.

"Games are becoming more and more graphically impressive" - on screenshots, maybe (still, they are just copy-pasting "reality", not really impressive for alter/digital world), but in action they are becoming more and more annoying. Soon all games will look same, they already do... As for me, it is quite boring and monotonous, and really not Impressive (Well, maybe, only if for a person with complexes or with psychological problems, who do not live, but simply exists)

Project Gamer If you're looking for a plateau, we've been in the 256 bit era for over two console generations. Even the Xbox One X and PS4 Pro are 256 bit consoles, as was the original Wii. Let that sink in for a moment. The only differences are processing speed, RAM, resolution, and a few other factors, but other than that we've essentially been using the same outdated tech for a while now.

Technically you're dealing with pixels regardless of how you render objects. But I'm assuming, though not certain, that you just bypass the vertex shading and go straight to pixel shading (or whatever method of drawing the pixel that's used). From what I understand, you need to use ray-tracing or ray-casting. I know a little about ray-tracing now, so I have a bit of an idea how it's all done now, but I'm still not sure.

I'm guessing without polygons, you're using a center point and the width, depth, and height of a voxel (or just a width if you're using cubic voxels) to determine whether or not a ray (from camera position) strikes a specific voxel (through a pixel on the screen). Then you just draw the pixel based on the colour of the first voxel struck. I'm going to look into it in more detail someday (hopefully soon).

You could use bezier curves, so that the mesh is infinitlely defined (kind of). check out this demo, not really pratical for rendering or modeling, but still show the point: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KYekhnLHGms.html

Nacim DarkDrifter In other words, use one or more mathematical calculations to draw each pixel individually like you might do if you wanted to draw a circle in two dimensions.

Nice question. I'd say make your 3D models with spheres, then cast a ray from each pixel on the screen to hit the sphere, and there it is. Another way is your models could be made of voxels each the size of a pixel, and do the raycast thing again to get the voxels nearest the screen. Another way is to make everything out of billboard points and draw an image to the screen at that point.

15k is quite low for AAA games. Most models are double that, with certain key models being 3-4x that amount.

Blueberry Bandit pc or consoles?

Polycount isn't that heavy that you are limited to 15k per model console and Pc games have models with 200k plus polys especially vehicles. (Lead 3D artist here)

Diego Salazar Consoles, and specifically for characters. I've seen models with as high as 85k on console.

for something like a gun, I usually stay under 10k verts

FreePenguin5000 cubes are made of 6 polygons

WarioGiant 😐

FreePenguin5000 what?

WarioGiant I didnt know that so I made a 😐 face

FreePenguin5000 well think about it: polygons are just any 2D closed shape and cubes have six sides made of squares which are 2D and closed and therefore polygons
