2D and 3D content in XNA

Drawing layers of 2D and 3D content in XNA on the Windows Phone.


private void OnDraw(object sender, GameTimerEventArgs e)
{
SharedGraphicsDeviceManager.Current.GraphicsDevice.Clear(Color.CornflowerBlue);

spriteBatch.Begin();
spriteBatch.Draw(background, mainFrame, Color.White);
elementRenderer.Render();
spriteBatch.Draw(elementRenderer.Texture, Vector2.Zero, Color.White);
spriteBatch.End();


Draw3DContent();

spriteBatch.Begin();
spriteBatch.Draw(cursorImage(), cursorPos, Color.White);
spriteBatch.End();
}


So this is a modified versuion of some code that i came to when drawing 2d stuff and 3d sutff using silverlight and xna for both 2d and 3d elements. The first chunk is going to be a begin and end for the background and some UI elements that are drawn in silverlight. then I have another function that has all of the 3d elements each chunk ending in mesh.Draw();
the last bit is to draw a silverlight cursor using xna sprite stuff since the cursor is animated and has several states.


I wasn't able to find an example of this anywhere so im posting it here.
