Talk:Bump mapping

message: The traditional method of surface normal perturbation (vector addition) can't be right, can it? e.g., if the surface normal is pointing at 45 degrees, and the bump normal is also 45 degrees, then the surface normal won't change at all. And if the surface normal is less than 45 degrees, then adding a 45-degree bump normal will aim the surface normal in the wrong direction (!)
Shouldn't the surface normal be rotated using the angular separation of it and the bump normal?  —Preceding unsigned comment added by 70.68.70.186 (talk) 17:14, 8 September 2008 (UTC)

replies: text: Yes, what's discussed in the article applies to EMBM bump mapping as well as dot3 bump mapping. Oddity- 03:46, 31 August 2006 (UTC)

text: EMBM is where they simply add a working environment map along with the height for great and acurate bumpy reflections. BobtheVila

message: The article is in dire need of attention from someone who knows about this stuff and is able to write proper English. I know a fair deal about computer graphics but was not able to understand what most of the sentences tried to tell me. I've added grammar and expert-verify templates to the article.

replies: text: As I note above, the focus also needs to shift from platforms and implementation details to what bump mapping is. I will try to improve the english as far I can understand the content. Dhatfield (talk) 09:32, 18 July 2008 (UTC)

text: I saw two problems. Firstly, the explanation was too technical, so I added the 'bump mapping basics' section. The second problem is with the English in the later sections - I will address this ASAP. The third problem is the structuring of images, but I don't have plans to fix this yet.

text: A agree with the platform thing and it never was my intention, only I wanted to include PS2 and GC in with the other consoles told to have done it. There was a problem with my paragraph on real bump mapping because of the tutorial it cam from. It was hard to convert it into simpler context.--BobtheVila (talk) 18:30, 4 September 2008 (UTC)

text: Also, theres a missconception on bump mapping basics, parallax mapping is not an alternative. Normal mapping needs to be used also or it will only stretch the pixels without changing direction. Also a tutorial states height mapping has no true data on it's own and neighbor relient. I guess the manner of usage would reveal fully.  --BobtheVila (talk) 22:37, 30 August 2008 (UTC)
replies: text:  Parallax mapping is usually an extension of normal mapping (in that normal mapping is done as well), not a "replacement", yes. Also normal mapping is a type of 'bump mapping' technique where instead of storing a hightfield which is used to calculate normals, the normals are pre-calculated and stored in the map instead (merging steps 1 and 2 in the currently listed algorithm). 60.240.243.216 (talk) 13:00, 30 March 2011 (UTC)

thread_title:  [[Bump mapping (sixth generation consoles)]] 

message: This entire section is horribly outdated. The information is from 2001/2002-ish, which is a lifetime ago in the field of real-time graphics. There has been so much research done in this area since then, that listing the "Realtime bump mapping techniques" from 2001 to 2011 could fill an entire page by itself.
This section should probably just be removed.

thread_title:  Realtime bump mapping techniques 

message: Hi, I am trying to convert the HTML list element type to Wiki markup in the section Realtime bump mapping techniques, but it did not go well for me. So I reverted, and tried again. But it does not display properly, so I will revert to the July 2019 edit. Sorry for the editing goofup. Jimj wpg (talk) 00:33, 14 August 2019 (UTC)
