-Real time fractal tree generation
-Artificial Neural Networks (AI)
-Genetic Algorithms (AI)

These do not interest me, and nor do other people''s suggestions (GUI, 2d techniques, etc.). Some advanced rendering techniques would be interesting, though. The bump-map tutorial should be updated for a start, www.nutty.org has a better one (not actually a tutorial, but vertex and pixel shader source code).

I am interested in your other ideas, especially if they focus more on the rendering than the physics (for example, the modeling of water has been discussed to death, but rendering of water is still difficult to do really well).

Shadow maps please

I came up with 2 more ideas for tutorials.

The first one is making things break, ie shattered glass, demolished buildings etc.

The second is networked games and how to use internet communication in your programs.

What do you guys think?

That second one really interest me. Perhaps two seperate tutorials could cover it. One on network communication (LAN) and another on Internet communication.

Sure

I''d really like to see the 2 AI tut''s, although I don''t think that they are really suitet for the NeHe site (which is mosttly graphics rendering). AI gives my quite a lot of problems and most tut''s and articles out there are really advanced. I hope you can put advanced AI in plain english.

i would like to read something about:

hooking an OpenGL Application. You write a .dll which u load before u start the OpenGL App. Then u can use some gl-commands to change/add some graphics on the OpenGL App''s screen.
(it IS useful for some advanced programmers)

also i would like to read something about "creating a simple realtime strategy game" (including AI, way-routing, etc...).. just a game like starcraft, but more more less complex! That would be great. ive never found such in the net.

An update:

Ive finished the water tutorial and NeHe is probably putting the finishing touches on it. Im still working on lightning, just debugging the code. After that ill do fog.

Once all of that is done ill show how to integrate everything into one game. Nothing big, but something sort of like Mario 64. Easy stuff Dont worry, its not that hard. I have a working demo that is just tweaks away from such a tutorial.

Once we have that 3rd person adventure environment ill put the ai, networking support in and the rest of stuff we have talked about. They should go in one tutorial at a time. Ill look into .dlls so that when we play each other over the net, the host .dll will be used. That way (im not sure but) we should be able to play with other people''s changes.

By that time we should have a nice 3rd person game. We can then rewrite the game into a strategy and whatever you guys want.

Various methods of bump mapping are documented heavily at nVidias developers site. Further tutorials on this are not needed. A decent water tutorial would be nice, although these are also elsewhere. For instance the deep ocean rendering and animation feature on gamasutra covers alot of ground. There are also multiple other tutorials on the net covering other methods of water simulation ( right down to ripples ). Shadow mapping is also heavily covered on the net.

A GUI tutorial would be nice, although you can pretty much figure that out for yourself anyway, so I don''t consider that a priority.

I think my point is this, if you have completed Nehe, then you should be able to just do alot of stuff yourself, like a console, or GUI. If not, there are other sites dedicated to advanced opengl, like nVidias developers site ( or ATI''s equivilent ), you''d simply be copying content by making bumpmapping and such tutorials.

Something I haven''t seen is a per-pixel volumetric fog tutorial, mind you, this probably comes under the "can work it out for yourself" catagory.

Death of one is a tragedy, death of a million is just a statistic.
