Bump Mapping

[adrenalin]

Hi.

I have to write a paper about Bump Mapping, but it doesn't become clear to me what Bump Mapping really contains.

What would you think are the main points I should mention?

Does anyone have or know a good, comprehensive summary of this theme? Links, books, anything...

Thanks a lot for help

just google it , you will get more then enough information about it

You can start with kristofs bump-mapping article here on b3d

Hi.
I have to write a paper about Bump Mapping, but it doesn't become clear to me what Bump Mapping really contains.

Start with the original paper, "Simulation of Wrinkled Surfaces", by (graphics god) Jim Blinn and work on from there.

The basic idea of bump-mapping is to simulate bumps on a surface by modifying the lighting equations that are done on a per-pixel basis, typically using one or more textures to represent the local properties of the surface.

The classical bump-mapping methods are:

• Blinn bump-mapping
• Emboss bump-mapping
• DOT3 bump-mapping
• Environment Mapped Bump Mapping (EMBM)

You should be able to find plenty of information on each method with a google search.

Tom has written a good article on Delphi3D : http://www.delphi3d.net/articles/viewarticle.php?article=bumpmapping.htm

Yes, I googled it. But there are many articles about it lighting the theme from different perspectives. e.g.: How is it implemented or what capabilities are there theoretically. Also there is not allways a general terminology.
That makes it difficult for me to get a structure in my paper. Thats what I need help for.

Here is my first idea:
1. Introduction
2. Bump Mapping generally: History, what is it in easy words
2.1. Theory/algorithm
2.2. Implementation
2.2.1. Embossed Bump Mapping
2.2.2. Dot3 Bump Mapping
2.2.3. Environmental Bump Mapping
3. Extensions of Bump Mapping
3.1. Parallax Mapping
3.2. Horizon Mapping

But there are certain more kinds of bump mapping extensions and I do not know where to but items like heightmap or normalmap.
Do you think this could be a good structure? What is missing?

@ Simon F: Can I get this paper anywhere for free? The only place i found it was at SIGGRAPH and there is nothing for free

Perhaps someone on the forum has a copy that could be emailed....
