How would I render a sky dome with XNA

I was looking for sky domes - a semi-sphere dome with a single texture wrapped around.

Is there any reason to favor boxes over domes, for say a spaceflight sim I would think the tradeoff is that a box involves fewer polygons, but a dome looks better.

They are both the same concept... keep locked to the camera position and rotate with the camera in one form or another.

The only things to base a decision off I can think of :

Domes:
You can do more with shaders. IE clouds skimming over.. multiple paralax.. a better simulation of a dynamic atmosphere and or background scenery.

Boxes:
Very fast and easy. Not really good for a dynamic background.. the only way would be to render a seperate scene to a cube map type scenario and only updating every now and then.

That said my first XNA game is using a Sky Box solution due to the fact that the scenery is static... also a correctly made and implemented skybox is hard to tell from a static dome. I had a space game I shelved that used randomly generated space skyboxes... it had very nice looking boxes no domes... though the professional game before last used sky domes my last ship was sky box based as it was the unreal engine....

Not much of a difference I guess but there is a little to base a decision on. =)... wow i got wordy on a simple question...

I'm using a skydome in my 4th series. Here's the chapter: XNA Skydome tutorial
