Thank you for your answer and I am sorry I didn't give enought info.
So first the geometry :
I have two rings of N vertices indexed 0 to N-1 for the first and N to 2N-1
for the second
1 *-----------------* 4
/ / \
/ * 2 /_-* 5
0 *--------------------*
3
every vertex has correct normal and position, so far I have
6 indices, 6 positions, 6 normals
I also use N quads : (*facepalm* just realized something, my indexing wasn't
that simple)
so in fact the index until now was just virtualy, it is the order in wich I
generate my vertices, my positions..
here the inexing for the quads :
indices->addValue(vertexlist[j]->index);
indices->addValue(vertexlist[j+1]->index);
indices->addValue(vertexlist[j+1]->index);
indices->addValue(vertexlist[j]->index);
and for the last quad :
indices->addValue(vertexlist[j]->index);
indices->addValue(vertexlist[0]->index);
indices->addValue(vertexlist[0]->index);
indices->addValue(vertexlist[j]->index);
this gives the following array : 0143 1254 2035
those are the correct quads
..this all works fine, but now I want a texture all around the tube

that would be perfect :) ..but how can I do that? this is my first selfmade
geometry (except for the water of the tutorial) I realy could need some code
examples ^^
There exist other methods for texturecoords like setTexCoords1 or
setTexCoords2 etc.. what are they for? could they be usefull here?
thank you for your help,
Victor
