Parallax mapping option as an alternative for displacement

<< < (8/8)

burnin:
There are daily cases where everything else fails and only high budget geometry offers a way.
Most prominent example in use for archviz is to look through windows, into a room or a tunnel, hole, a portal of any sort. It's so often used that's become banal and surpasses use of clouds. Cuz when one is occupied, there's rarely time to invent and after, old habits die hard.
It would also makes it easier/cheaper & faster to animate far-away/mid to low LOD objects (use billboards instead of 3D), even representing surfaces under water/in volumetric objects... to ease and speed up actions which are repeated most often is where most benefit  is coming from.

Imagine rooms scattered over houses, blocks & skyscrapers, then buildings & skyscrapers scattered in back... or it could even be starting w/ grass, bushes, trees, animals, ppl... whatever entourage comes to mind. IIRC, ages ago there was a 3DS Max plugin which also provided whole library sets supporting such workflow.
Somebody surely remembers...?

maru:
We are still not convinced parallax mapping would be very beneficial. It looks like there aren't many common uses cases for this. Sure, it would be nice to create a skyscraper with rooms you can peek into and they are actually flat textures, but I don't think it would be commonly used. There are also some workarounds to this, like using OSL.

We would still prefer to improve our displacement if needed, than to develop a new feature like this.

Of course, if someone can share a good example of how parallax mapping (or decals with parallax) would be useful, please do.

Juraj:
Parallax alone is quite useless, and the use-case of projected rooms is easily done by great OSL commercial plugin.

But Parallax Occlusion mapping can great alternative to normal mapping before stepping to Displacement, but that depends purely on render-cost and I have only seen it implemented in F-Storm, and I have no idea what performance penalty it brings.

To allow future tracking (even though we still have the same concerns as mentioned here), an entry was created on the Ideas Portal at https://chaos.aha.io/ideas/ideas/CMAX-I-32
