Ah, image reconstruction... there's a lot of info on that on the net.
For now, given almost infinite time, stick with this scenario:

1. Make a prism or cone with its vertex at location and its base
extending about as much beyond look_at. Have it pass through a pixel
of the image and be of approximately the same visual size.

2. Repeat for all pixels

3. Union all those cones

4. Repeat 1-3 for all viewpoints

5. Intersect all those unions

6. Grow old waiting :)
