Another way is to use a special camera...
This method will distort the texture (or scene) in strange ways, but it
remains absolutely clear and unblended.
In the code below you can replace the textured sphere with any scene, and
you can change the location and look_at of the camera to whatever you wish.
You will be able to get some really interesting effects...

// Width and height of output image must be equal.

camera {
   ultra_wide_angle
   location <0,0,0>
   up y
   right x
   angle 360*pi
   look_at <1,1,1>
}

sphere {
   0, 1
   pigment {spiral1 1}
   finish {ambient 1 diffuse 0}
   hollow
}
