Photogrammetry has started to gain steam within the Games Industry in recent years. At DICE, this technique was first used on Battlefield and they fully embraced the technology and workflow for Star Wars: Battlefront. This GDC 2016 talk from DICE's Keneth Brown and Andrew Hamilton covers how they built the technology and process to scan props from the Star Wars films to generate assets for the new Star Wars Battlefront.
GDC talks cover a range of developmental topics including game design, programming, audio, visual arts, business management, production, online games, and much more.

@bananaboy482 7 лет назад

yea its amazing

@d3tach3d 6 лет назад

alot of apply to there amazing renderer. They can cut down on polys with such a nice Physical Based Lighting and Texture detail. Were getting to a point where polycount in individual assets is becoming "enough" because we can focus most the realism/detail with normal maps and/or displacement maps with tessellation. I think the big things to tackle now are more assets on screen, animation, and physics to hit that next big step in realism. We already have ability to achieve photorealism just not in "realtime" time. All that would take is processing power which we are achieving. It's amazing that we are at this point to where our software/algorithms are just waiting for the hardware to keep up along with optimization of course

@Jester497 5 лет назад

@galaxiesaver Not really, virtual texturing, invented by id software, fixes the memory problem of textures pretty nicely. The big players just need to implement this solution in their engines (which is what Epic is doing right now for the next version of UE4). The lighting problems we still have will be fixed by path tracing (which is still a shit ton of time away though), so the big problems to tackle will be object count, physics and draw distance.

"Yes I'm so glad someone asked about the tree capture" *video cuts off* XD

@iFukuyama 7 лет назад

You can see the last few minutes on the GDC Vault page. Basically, they photographed the trees at an angle (standing on the ground, looking up) and used that data as far as they could, and supplemented it with traditional hard surface modelling on top. Because there are many trees, anything above 10m is very low poly, but the bark and moss make it look good.

@jimmysgameclips 7 лет назад

I'm a little surprised, but also it makes a lot of sense for the game. Neat, thanks

Almost a shame that these levels are "wasted" on online gaming only. I could easily see myself wanting to explore these landscapes in a single player mission without any time pressure and just appreciate their wonderful work. With online matches, no one can really pay much attention to these backgrounds.

Imagine an open world game like skyrim or the witcher with this quality graphics. Hopefully ES6 will use next gen techniques and look absolutely badass.

@RiderZer0 7 лет назад

Clevver I think there are several mods for skyrim that use photogrammetry. Just something that might tie you over until es6 comes out. Which may be another decade.

@mso1ps4 7 лет назад

Clevver That would be amazing. I can't imagine how much work that would take or how big the game file would be, though.

@eborge9711 7 лет назад

Photography isn't great for fantasy games. As they mentioned themselves, you still need to 3d model objects that don't exist in the real world. Skyrim and witcher have a lot of fake species and races of people. Though, their other tech is very impressive. Their use of detail maps is very impressive.

@maan7715 5 лет назад

@@CrackedTubeGamer And they just announced they are using photogrammetry for the upcoming games and working really hard to update their engine. I'm disappointed as well that it will be the same engine, but I kinda have more hope now. And they are finally using substance painter as well.

@TheApaura 8 лет назад

Assassin's Creed would honestly benefit from this the most, for obvious reasons. Amazing visuals with amazing performance, and more development time on content. Ubisoft must adopt it, for commercial and development success.

@jokesterthemighty227 8 лет назад

you call 30fps amazing perfomance?

@anabukashka 8 лет назад

AC Unity already looks amazing with it's next-gen Anvil tech.

@TheApaura 8 лет назад

Jokester The Mighty Battlefront didn't run in 30fps on console, so why would Assassin's Creed with photogrammetry? Honestly, unlike multiplayer, single player games don't fundamentally REQUIRE 60fps. It's great to have it, but I'm content with a stable 30, so are a millions of others.

@TheApaura 8 лет назад

Alexander Abdulov Still has got nothing on Battlefront, and performance could be boosted with this technology. So essentially we'd get better graphics with better performance.

@HenkkaArtGames 8 лет назад

When you talk about "this technology", what do you mean? Photogrammetry or Frostbite engine? Because photogrammetry alone can't save a game from bad performance if the underlying engine is not up to par.

@xplorer3475 7 лет назад

really great. Any idea of how they setup their object space normal map in photoshop, to remove some ambiant lighting and shadows informations, with a black and white filter ? i don't understand how they set this up

@soggyclog 7 лет назад

They're accessing the individual RGB channels of a normal map in photoshop (from the Channels tab). The black and white mask you saw was one of the channels visualized. Each channel in the normal map corresponds to an axis in 3D. Typically R=X, G=Y, B=Z. So for example if the shadows are in the Y axis, they can CTRL+Click the green channel to select the pixels facing towards Y (or invert it for the opposite direction). Then they can just paint over those pixels or colour correct or whatever.

@xplorer3475 7 лет назад

thanks a lot !

@jonathanxdoe 8 лет назад

I wonder why ZRemesher was not good enough for them. I find it crazy good to create low poly organic assets, plus you can always correct them.

@xplorer3475 7 лет назад

it can be good yeah, especialy for such assets which aren't faces. personnaly i like to do a first zremesher, then a dynamesh on it at low res, smooth it, then re reun zremesher, it gives better results for the low poly version. but maybe they didn't use it since they want to have more control on the topology, to later have a better uv layout, well optimized, and no deformation.

@jonathanxdoe 7 лет назад

Thank you for the suggestion, I'm checking some videos but it doesn't look half as good as ZRemesher to be honest... Even giving some direction it won't produce a result as natural as ZBrush. Anyway I gonna try it if it's actually free.

@Deck_Dynasty 6 лет назад

Why does reducing texture size to 512 and then adding detail texture reduce texture memory? It's an extra texture lookup. Were the detail textures like 256? Also, were the detail textures simply tiled over the entire bark? @ 24:00

@swaterik1986 7 лет назад

Does anyone know how they remove the light/shadow information with the object normal?

@MrLysaght 7 лет назад

Object-space normals gives you surface direction information. That means you can select pixels facing a specific direction around your object. If you know the light direction on your source data, you can easily suppress it by selecting pixels pointing to this light source and bring their brightness/exposure down with some Photoshop magic. Invert the process for shadows. Well, I mean I guess that's how they've done it.

@SuWoopSparrow 6 лет назад

Art is creative and interpretive. Using scans as a base? Sure. What they did with the terrain is awesome. Sculpting it in person and scanning it. That's creative and interpretive. Using scans verbatim isn't artistic. Scanning Norman Reedus isn't artistic, regardless of how much labor is involved in the process.
