Pour créer un effet de vagues sur l

Pour créer un effet de vagues sur la surface, on aura besoin
d’une carte de normales. On pourra utiliser une telle
carte de texture pour y retirer des valeurs qui seront utilisées
comme normales sur notre surface.
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.
Pour ce faire, il nous faut au minimum la normale et la
tangente de la surface d’eau exprimés dans le repère global.
Puisque le plan d’eau est statique, la normale n, la tangente
t et la bitangente b sont toujours identiques. Notons qu’une
déformation de la géométrie modifie ces vecteurs (voir la
section 2.6).

to create an effect of waves on the surface,
will need a normal map. can be used as a texture map
y to remove values ​​that will be used as normal
on our surface.
first of all, make sure to be tangent mark.
this is important, because normal that is extracted
of the texture map are of course in the reference object
(Reference tangent). 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.
to do this, we need at least normal and
tangent of the water expressed in the global reference surface.
because the water is static, normal n, tangent
t and b Tangent are always identical.
note that a deformation of geometry change these vectors (
see section 2.6).

To create an effect of waves on the surface, we will need
a normal card. You can use such a
texture map to pick values that will be used
as normal on our surface.
before all things, be sure to mark tangent
is important, because the normal is extracted
the texture map are of course in the subject mark
(tangent mark). Therefore, move our vector
light l and the v in the tangent landmark perspective
order to correctly implement our model
lighting.
to do this, need us at least normal and the
tangent of the surface of water expressed in the landmark global
since water is static, normal n, the tangent
t and the both b are always the same. It should be noted that one
deformation of geometry modifies these vectors (see la
section 2.6).

To create an effect of waves on surface, there will be besoin
d' a chart of normals. One will be able to use a telle
carte of texture to withdraw there values which will be utilisées
comme normal on our surface.
Avant 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' éclairage.
Pour correctly this to make, it is necessary the normal at least for us and la
tangente surface of water expressed in the global.
Puisque reference mark the water level is static, normal N, the tangente
T and bitangential B are always identical. Let us note that une
deformation of the geometry modifies these vectors (see la
section 2.6).
