Rendering inside out

I'm trying to figure out how to render a skysphere, and my understanding is that you essentially create a sphere and render it inside out.That way, the camera can be in the center of the sphere, and the sphere's texture shows up on the inside. I'm sure there is a way to do this, but I haven't found it as yet. Is this something a shader would do If so, where is a good resource for HLSL I haven't a clue how to use that. Thanks!

I have another solution for you. Setting culling to ccw is an option, but you can also invert the definition order of your vertices from cw to ccw! This can be done automatically for you using a nifty tool created by Rene Jeschke, and which you can download from my download page. Load your .x file, select the cw to ccw conversion and save your file again. This way, you won't have to bother about changing renderstates anymore.

You can turn off culling before you draw it.

Something like:

GraphicsDevice.RenderState.CullMode = CullMode.None;

<Draw sky>

GraphicsDevice.RenderState.CullMode = CullMode.CullCounterClockwiseFace;

Or when you create it, you can tell your 3D modeling package to invert the normals or draw them the other way before you export it.

Thank you, this is definitely working! Game design is definitely tough, XNA really does help to ease that learning curve. I've got a test skysphere working now!
