Ever wondered how google maps street view works?

I happened to be on the Google Maps iPad Application and I went to street view and for some reason it refused to load any graphics. Now we all know that the street view is a series of spheres that you move from the centre point of one sphere to the next sphere as you move down your street and the photos that were taken by the street view cameras are displayed on the inside of the sphere as a texture. Due to the nature of these textures being photos of real life objects. They show distance which means that the texture does not make the sphere look like a sphere
As you can see from the above picture the effect is really good and it doesn't look like a sphere. Now what happens when the google map application refuses to load the photos.
As you can see from the two photos above the background world texture is applied on the blue and yellow bits.
