There are no quad strips. Only triangle strips. Quads get broken down to triangles by the drivers, so might as well use triangles in the first place.

1-3-5
|.|.|
2-4-6 etc

glBegin( GL_QUAD_STRIP )
glVertex3fv(1);
glVertex3fv(2); .. 3.4.5.6etc
glEnd();

using quads instead of tris require less typing and also for certain things its easier to see whats going on eg make a sphere with quads + tris, view both in wireframe or the quads look better

Oh yeah, sorry, I know all that... I am more interested in the order in which the vertices need to be declared.

Sorry for the mis-information,

I have figured the order out using trial and error now..

I have a different problem though.

How do I select different textures to be used on diferent quads?

I can select a texture to be used.. but selecting textures in between the glBegin(GL_QUAD_SRIPS_ and glEnd functions does not work(in this case anyway, it must work for some). So how do I choose a second or third texture?

Since vertices overlap with strips, how am I to select 2 textures for those vertices.. I''m guessing that I don''t.. so whats''s the deal with this! Strips seem only good for coloured polygons, or those that require just one looping texture.

theres a few things u cant do between begin..end statements binding textures is one of them. u will need to use multiple calls to begin(QUAD_STRIP) end()
