Normal transformation and homogeneous coordinates I did not complain, I perceived an aggressive intent and I was wrong. I apologized for the misunderstanding and credited Nicol Bolas for his help both in the comments and in the question way before your intervention. So I'm wondering what is your contribution to this argument besides the whole pointless discussion on who knows what. |

Normal transformation and homogeneous coordinates Benefit of the doubt is an important part of the scientific reasoning |

Normal transformation and homogeneous coordinates @Nick Wiggill: I don't agree with you, criticism and directness can be counterproductive and I don't consider them at all part of teaching and learning. You should never take for granted the background of a person, especially when you infer it from few lines in a discussion forum. I come from a mathematical background and if someone replies to a question of mine saying that something I'm sure of is totally meaningless (see the first part of the answer) I take it as an aggressive response and he loses credibility to my eyes (which is not constructive). |

Normal transformation and homogeneous coordinates Ok sorry for the misunderstanding, then. Although, I think I made the mistake of taking for granted some assumptions. I'm not talking about homogeneous coordinates in a perspective transformation but in an affine transformation. See the edit of the question. |

Normal transformation and homogeneous coordinates Moreover, I'm trying to see the problem from the math perspective (as I wrote in the question) that's the reason I linked that article. I was expecting a response related to that model, not a response attacking it. |

Normal transformation and homogeneous coordinates Please refrain from such aggressive response, they are not constructive from the OP perspective. First of all it does make sense to take the dot product of a position/vertex with a normal (for example take the algebraic equation of a plane dot(P,N) = d). |

How does UVW texture mapping work? Thanks a lot, that's what I was looking for |

How does UVW texture mapping work? @Byte56 What does that mean? I know how U and V are used, but W? The texture is 2D flat image, what is the 3rd dimension? And more importantly how should be used. Give me a formula or something... |

How does UVW texture mapping work? Thanks, but still it is not clear to me the meaning of W. Is there some kind of book to follow? |
