How to render bezier curve with D3D?

I'm writing code to make my camera moving in cubic bezier curves, and I think it'll be nice if I can see the camera track, but I just don't know what's the right way to render the curve.

Is there a way to render a 3d bezier curve other than breaking it into line segments?

Thanks.

You will always have to split the curve in some segments, I think there's no way around.

On though I just had, perhaps it is possible to split the curve in quad segments and the apply a special fragment shader to it which calculates the curve in this quad pixel perfect.

Or u can just tesselate the lines in a geometry shader so that lines near the camera look smooth

I think lines segments will be ok in this case, Thank you !
