I know what bump mapping is. I know what normal mapping is.
But now the new buzz word is parallax mapping and I have no idea
what that is. Anyone have any good explainations or links discussing it?

 

[lollerskates]

is Perfect Dark Zero the first game with parallax mapping.

 

[HooDoo]

And normal mapping too, please. Or whatever it's called.

 

[SantaC]

i believe doom3 can have parallax mapping

 

[Sapiens]

Because you were too lazy to search the forums, so am I, but an excellent explanation can be found....

 

[lollerskates]

i believe doom3 can have parallax mapping

i thought that was only using a mod though.

 

[TekunoRobby]

i believe doom3 can have parallax mapping

This is true and here is the mod to enable it: http://doom3.filefront.com/file/Parallax_Mapping_Mod_v10;29475

Really good description of parallax mapping --

Bump mapping

Normal mapping

[Raiden]

And Half Life 2, people just say it because PD0's heavily usage of it, its been around a while.

I'd also like to add this website which has a good comparison of all the texture rendering techniques and gives a decent technical explanation of what Steep Parallax Mapping is (the step above regular Parallax Mapping).

[JRPereira]

Whoah, nice find Robby.

 

[Raiden]

Yeah really nice Googling guys: http://images.google.be/images?hl=nl&q=Parallax mapping&sa=N&tab=wi

I doubt anyone knows here what Parallax mapping is exactly, besides the graphical difference they can see.

EXEPT ME CUZ ME>ALL1!1!1!1!1!11!1

 

[JRPereira]

Well if you want to simplify it I would say it's like per-pixel displacement mapping - creating virtual polygons or tacking voxels onto polys.

It makes me wonder - would you be able to do collision detection that matches what you see from parallax mapping?

 

[TekunoRobby]

Nope since its still mapped onto a flat plane. On future texture rendering techniques? It could be possible, I haven't the foggiest.

Speaking of voxels (volume pixels) I loved that goofy ass technology. Anyone ever play Delta Force 2 or Outcast?

 

[Lathentar]

Delta Force 2 was amazing. So many people on a map, quite the feat for the time and huge huge levels.

 

[Mama Smurf]

Is there a reason for the smooth, shiny, plasticy crap look so many of the examples seem to get?

BTW, Kameo uses Parallas mapping too...

Thanks for reminding me, here's one of the best examples of parallax occlusion mapping available:

Pay special attention to the sign and the cobblestone street. If you haven't seen this video you'll be absolutely floored by what you can acheive with some shader effects, great particle effects, and beautiful texturing work. For the technical minded there are over 700 unique shaders, volumetric lighting, and dynamic soft shadows being used as well.

HL2 doesn't support it yet, but in a few updates it will. Unless the Lost Coast had it...I didn't notice it.

You can basically convert your textures into parrallax maps and actually use them in game, but you don't see the proper result, you just see it as a flat texture, until the appropriate Steam update comes along and then you'll notice it.

 

[mrklaw]

whats the overhead? surely this is a v.complex shader. So how does this technique compare to drawing some actual bumpy floors from polys?

Going by Perfect Dark Zero, it's overhead sucks all talent away from the art director and 3D modellers.

 

[SantaC]

therefore I called it "can have"

 

[conker]

Actually drawing bumpy floor/walls would be RETARDED with current hardware.
Nevermind the development time it would require.

And voxels rule. They worked out niceley in Tiberian Sun.

Parallax Mapping: Someone found the long hidden Inner Bevel / Emboss command in 3DSMax


:lol

 

[Sinatar]

FEAR used parralax mapping for all the bullet hole, wall deformation effects before PDZ came out.

parallax mapping is old news. Relief Mapping is the new hotness.

 

[Speevy]

After playing Kameo, I'm confident it's something that at least two consoles can do easily.

 

[Warm Machine]

It is also knows as an offset shader. You can find one for 3ds max at...

Relief mapping is unbelievable.

I'm serious...I just don't believe it could be done.

If someone could use relief mapping in a game and it didn't bog down the hardware...there's no excuse for real looking games.

 

[JRPereira]

Oh dude, I just went and read a bit about relief mapping and dayam. If I read that right, that's freaking awesome.

There's a movie of relief mapping WITHOUT self shadowing.

But with self shadowing it would be the ultimate form of texture mapping.

 

[The Shadow]

I'm actually not too impressed with parallax mapping. That picture with the lion shows why. Things start to look really ultra shiny when they're pulled out too far from the flat plane. It's somewhat obvious in the Doom 3 Parallax mod and really obvious in the improved parallax mod for Quake 4.

 

[Miroku]

it appears to be creating the illusion of extra geometry by stretching pixels, which would in turn stretch the specular masks of the shaders causing there to be a lot of undesirable shinyness. Areas highly affected by the relief map should have their specular maps toned down to minimize that effect.
