Bump Maps: Possible?

[Dr.]

Well... I'm tired and I don't want to write a wall of text so I'll leave these here and comeback later to further explain.

4-8Mb gifs Ahead, be patient and let them load.

Sorry but you are not allowed to view spoiler contents.

@Tcll
^This is what I'm talking about. If you don't want to further research because it's not proper Normal Maping, that's totally fine. I might look into it sometime, but not right now


Note: I know these are crappy zoomed-in gifs but my connection is extremly slow to even think of uploading videos to youtube, so deal with it. If you want to take a better look, go to Melee and look at Giga Bowser trophy; or Brawl and take a look at Sages trophy.
I might edit this if I manage to get my thoughts straight.

that's actually not all that bad for quality... :)

yea, I do see the bump-mapping effect a bit...
IDK... last place I can look is the materials...

it's not an NBT model, but it does have an interesting effect >_>

[Dr.]

The only downside: there's only one texture in the Sages MDL0 for the actual body, and that's the ""Bump Map""

And that's probably why it doesn't look like Bump maping in the sages.

I'm an idiot... I didn't realize, bump map vs normal map

the difference between them is a normal map actually follows light...
the bump map only modifies the light no matter what direction you look at it.

for a bump map, rotate both the model with the light, and nothing should change in appearence if I'm correct.
where the lighting would change slightly with a normal map.

the seiges only has a bump map, not a normal map, where G-Bowser has a norml map and a bump map.
(I havn't actually seen the normal map, but the NBT vectors make me think one exists)

Having dealt with such maps in Game Art Assets over here on campus, I can tell you that you that you're correct. Normal Maps react to the lighting, while bump maps do not. It'd be really cool if we could get bumps or normals to work on characters, cause it would increase what we can do with these textures we make and other similar things.

I envy you... lol

anyways, not just ncrease what we can do, but more show the power of what the Wii can do.

I wanna try to get Brawl to support the v11 MDL0 format so I can actually give Pika his fur. :P

normal mapping can be used to make his eyes look better and so on...
(I don't have to explain everything, use your imagination) :P

my knowledge from this also comes from Nexuiz

I'm just a little curious if the wii could actually support depth sampling
I forget the term honestly, here's what I mean: (look at the walls and the floor)


I used to have a GL sample that made a floor look like gold bricks...
I think it was called oversampling or something...

Well, I found something interesting while running about, Tcll.

Look into Environment-Mapped Bump-Mapping?

[DarkPikachu]

Look into Environment-Mapped Bump-Mapping?

recently no... I've been going off legacy knowledge about it (very little) fo a while...

I'm currently designing the scene graph of my dual-ended graphic interface...
(I'm expecting the VIEWER plugin for UMC v3.0 to be able to render CryEngine3-quality graphics upon it's first release)
^I've gotten knowledge from Ian Mallet to help me out with this.

I'll get there though... eventually :P


however, I am interested in your findings :)

Well, my findings sadly only amount to looking around for the types of mapping possible for the Wii, EMBM came up and it sounds interesting.

well heck, I'm interested ;D
any sources or cites?? :)

Well, Technopedia has a very sparse rundown on it, that may be a place to start.

[DarkPikachu]

ah I think I found it: http://www.techopedia.com/definition/26365/environment-mapped-bump-mapping-embm
boy this is quite sparce, but I think I understand it...

I'll have to look up a few other things to fully get the idea :P

I'll get to it when I get to advanced materials ;)
(the modern materials used in shaders which use more than the 5 basic definitions)

EDIT:
here's a better explanation: http://www.anandtech.com/show/298/5

[Dantarion]

Falcon has a spec map doesn't he?

[DarkPikachu]

yea, but that's just specular... neither bump nor normal

unless I'm missing what you're pointing at :/
