Looping textures

[Oenone]

I've created an object in my vertex buffer which forms a tube around the
y-axis, and I'm rendering it using DrawIndexedPrimitive, such that the
points where the start and end of the tube meet are the same points in my
index buffer.

I've wrapped a texture on to the tube, and it looks fine, but because the
texture's u coordinate is 0.0 at the start of my tube and 0.9 at the other
end, the join between these two points (where the tube end joins back up
with the tube start) repeats the entire texture, compressed into a tiny
space and back-to-front.

I'm sure I have read about an easy way of stopping the texture from doing
this, so that in this section the texture coordinates will range from 0.9 to
1.0, instead of 0.9 to 0.0. Have I imagined this? And if not, could someone
remind me what I need to do?

Many thanks,

d3dDevice->SetRenderState(D3DRS_WRAP0, D3DWRAPCOORD_0);

That'll specify that U coordinates are wrapped for texture stage 0.

Perfect -- many thanks for that.
