The OSG allows you to share arrays so there isn't a problem. If you
don't want to share then just now reuse the same array over and over
again.

Hello,
In my geometry I've got 7 different texture (which correspond to 7
different faces) and I want to store
the texture coord of my vertices in 7 different TexCoorArray. Do you see
what I mean ?
My code is:
osg::Vec2Array* texcoords = new osg::Vec2Array;
for (noFac = 0; noFac < nbFac; noFac++) {
optCarTer.facette = noFac;
GeolibTerCarac(fid_ter, GEOLIB_TER_CAR_NUMFACE, &optCarTer,
&noFace, p_erreur);
VerifCode(OASIS2OSG_ERR_GEO, -1);
optCarTer.face = noFace;
GeolibTerCarac(fid_ter, GEOLIB_TER_CAR_NLIGTEX, &optCarTer,
&nligTex, p_erreur);
GeolibTerCarac(fid_ter, GEOLIB_TER_CAR_NCOLTEX, &optCarTer,
&ncolTex, p_erreur);
for (noSom = 0; noSom < 3; noSom++) {
optCarTer.sommet = noSom;
GeolibTerCarac(fid_ter, GEOLIB_TER_CAR_COORDTEXSOM, &optCarTer,
coordTexSom, p_erreur);
VerifCode(OASIS2OSG_ERR_GEO, -1);
texcoords->push_back(osg::Vec2((marge+coordTexSom)/(ncolTex-1),
1-(marge+coordTexSom[0])/(nligTex-1)));
geometry->setTexCoordArray(noFace, texcoords);
}
}
The problem is that all my texture coord are store in the texture unit 0:
in my file I obtain:
TexCoordArray 0 UniqueID Vec2Array_0 Vec2Array 366
{
0.44427 0.498689
0.564294 0.499072
0.564435 0.587068
0.44427 0.498689
..... etc.....
}
TexCoordArray 1 Use Vec2Array_0
TexCoordArray 2 Use Vec2Array_0
TexCoordArray 3 Use Vec2Array_0
TexCoordArray 4 Use Vec2Array_0
TexCoordArray 5 Use Vec2Array_0
TexCoordArray 6 Use Vec2Array_0
Thanks!!
