Avant toutes choses, il faut s’assu

Avant toutes choses, il faut s’assurer d’être en repère tangent.
C’est important, parce que les normales que l’on extrait
de la carte de texture sont bien sûr dans le repère objet
(repère tangent). Il faut donc faire passer notre vecteur
de lumière l et celui du point de vue v dans le repère tangent
afin de pouvoir appliquer correctement notre modèle
d’éclairage.

結果 (英文) 1:

first of all, make sure to be tangent mark.
this is important, because the normal
extracted from the texture map are of course in the reference object
(tangent benchmark). it is necessary to get our light vector
l and that of v terms in the reference tangent
order to correctly apply our model
lighting.

結果 (英文) 2:

Before all things, be sure to mark tangent
this is important, because the normal is extracted
of the texture map are of course in the landmark object
(repère tangent). Therefore, move our vector
l and light that from the point of view v in the tangent guide
order to correctly implement our model
lighting.

Before all things, it should be made sure to be in reference mark tangent.
C' is important, because the normals that one extrait
of the chart of texture are of course in the reference mark objet
(tangent reference mark). It is thus necessary to make pass our vecteur
de light L and that from the point of view v in the reference mark tangent
in order to be able to apply our modèle
d' lighting correctly.
