| Another excelent tutorial. It's articles like these that keep me coming back to GameDev. Honestly, you should think about compiling all this for a book. Great job!!!!! D.V. Carpe Diem |

| He is, actually. A lot of this material is the basis for his book ShaderX, which should be coming out this year from Wordware. I'm personally glad to see that these articles are well received. I know Wolf has put a lot of work into them: almost a year and 160 pages worth of text. |

| Quite simply, this series is the best introductory-level material ever made on shaders - in any media. I haven't encountered a website, book, or article which has the same clarity, depth, and level of detail. Not that it is perfect, it is bit too 'how-to' in nature. I would've preferred more 'why-so'. But these minor flaws. Amazing work. I already preordered ShaderX - it looks like a great shader resource, with a smorgasbord of different topics. Somewhat like what I expected, but didn't find, in Special Effect Game Programming with DirectX. |

well, this is another reason why gamedev is better than flipcode  . |

| I kind of doubt anyone checks this thread anymore, but in this tutorial, the constant that is being set called fLightPosition. It seems to me that that is actually the direction of the light. Is this a correct assumption? Matt Hughson __________________________________ [ Website ] [ Résumé ] [ Contact ] [ Have I been Helpful? Hook me up! ] |

Quote: It's in the source. But even in the tutorial he uses the #define LIGHT_POSITION which seems a little off to me. Edit: Yeah I positive its just a typo now, as the defines change to Light_Vector (or something similar) in the tutorials that follow; not to mention its a directional light, so it has no position.
