Parallax mapping is also how RDR2’s landscape textures look very detailed at times. All the little rocks, dirt, paths look like they’re tessellated but a closer look at them reveals it’s parallaxed

0:33 i just love how the interior changes in a split second when the protagonist crawls around the corner. Suddenly, a kitchen area turns into a dining area with a door on the left that leads you out of the building on the 30th floor.

Indeed a limitation of the technique, but I’d argue the profits (greatly) outweigh the expense. Also, this could be used to great effect in another game to be purposefully ‘trippy’.

[@farhadaa]

A common problem with parallax mapping on surfaces that characters stand on is that it makes the player look like they are floating above the ground, as is seen when turning around in Genshin impact.

[@Mempler]

One way to fix that would be to clip the player just a tiny bit into the ground. Just enough that it still looks Natural

[@user-oo7dw4qw4b]

I'm not well versed in 3D but couldn't they have used normal maps instead of displacement maps? Normals may not be the best for low end devices but it could be visually better. But then again it's a game and not really a render piece.

[@Yotrymp]

@@Mempler The character will still look like they're sliding on the ground.

[@theminecraft4202]

@@user-oo7dw4qw4b both normal maps and displacement maps are used, the difference is that a normal map tells how a surface interacts with light, while a displacement map is more about what parts of the surface the player can see (the whole "fake depth" bit from the video). To get the best kind of results you want to use both since they provide information on different aspects of a material

[@Mempler]

@@Yotrymp oh yeah true due to it not being really transparent but rather an illusion hmm. What if you multiply the intersection with the height map?

4:16 The Bedroom in this Parallax Cubemap is amazing! It gives the illusion of a second room, that is wider than the cube itself

[@simoncowell1029]

That does look really cool ! I think that the extra bit is distorted, if you look really closely, because they are pushing the technique quite far. It's like the original problem of textures with depth looking too flat, but they've buried the problem one level of illusion deeper than normal. My brain didn't even notice the distortion, first and second time around.

Really interesting. Thinking about how older games handle this, it's usually that every window has glare on it / reflects the sky.

It's fine from a distance. parallaxing seems to be the next step up. Easter egg should be one room you can actually interact with :D

Don't get confused by Parallax and Tessellation *1.* Parallax is a 2D Fake 3D to fool your eyes, it's the old tech used first in FEAR Game back in 2005 on PC, and it was supported by DirectX 8 & 9, DirectX 9 has higher depth and improvement over DirectX 8 *2.* Tessellation is a Fake 3D Cover of the lower polygons, which makes it completely High polygons, that you can't see a single square or visible polygon, it was used first in DirectX 11 Games Like S.T.A.L.K.E.R.: Call of Pripyat on Characters model

then you get into texture atlases texture arrays or 3D textures and instancing or computes allowing you to render this single polygon with one draw call for thousands of windows saving alot of CPU time and GPU bandwidth and memory if you so wish and the only thing that changes in between the drawcall is the cubemap layers or the texture array position, for a myriad of different combinations of these rooms. and the texture is also only loaded on across the pipeline. but honestly, this is the good thing about having hardware performance stagnate for a period of time, developers tend to get REAL creative regarding these sort of things to get MORE onto the screen for less. then when new faster hardware comes around they still don't move to the real deal instead they improve on their earlier tricks to make them look even better and vastly better performance still.

I feel parallax rooms look great from afar, but when you get too close the illusion breaks really badly. Furniture painted on the back wall, corner rooms not matching up, doors leading directly to a 20 story drop... perhaps masking the cubemap with semi transparent curtains or blinds to obfuscate the shapes behind them would help sell it immensely.

Blade and Sorcery uses this as well to conceal unloaded areas you would see through open doors. The only issue is that it isn't replaced with the next loaded area before the effect is noticeable to to the player.

In Godzilla vs Kong they used the same technique on the windows of the buildings i and Hong Kong. Since they had built a 1-1 Hong Kong replica in 3D, finding anywhere to trim geometry was key. Parallax Window mapping helped boost the visual feel of the city without adding additional render time.

It's one of the small things that I liked in playing the GTA Trilogy Definitive Edition (as it was my first experience with 3 and VC). I just liked staring at the windows.
