"Science Fiction is speculative fiction in which the author takes as his first postulate the real world as we know it, including all established facts and natural laws."

Prior to his stay on Iszm, traveler Aile Farr was forced to sit still for an exquisitely accurate biometric identification method.
| "On the gray disk, Farr Sainh - palms forward, eyes wide."
He stood rigid as feeler-planes brushed down his body. In a glass dome a three-dimensional simulacrum of himself six inches high took form. Farr inspected it sourly. |

The feeler-planes were able provide remarkable details about a surface - including finger-prints - in a completed tri-type record.
The problem of 3D model acquisition (the digitization of a real, three-dimensional object) is more difficult than you might think.
(Acquisition with light source, camera, calibration target, test object)
It is particularly difficult to obtain digital models that correctly capture fine texture details:
Several views of each object are captured with different camera and light source positions. For each view, we acquire a series of photographs of the object lit by the point light source, with varying exposure time from which a high dynamic range image [2] is calculated. After calibrating with the known brightness of the lamp, each pixel of the high dynamic range images contains full range, floating point radiance samples. Furthermore, we take two images to recover the light source position relative to the camera and one image of the object's silhouette to register the 3D geometry model with the images [8]. In a production environment, the 3D scanner, camera, light source, and the test object could be combined into single, calibrated gantry to speed up the acquisition process and to render the registration unnecessary.Read more at Digital Collection of Real World Objects.

'Their only check on the growth and development of Vulcan 3 lay in two clues: the amount of rock thrown up to the surface... and the amount of the raw materials and tools and parts which the computer requested.'
'I guess there's nobody round this table who doesn't have a Crosswell [tapeworm] working for him in the small intestine.'
'Figments of his mind in one sense, of course, for he had shaped them...'
'So the parent drone carries a spotter that it launches...'
'...nurse drones that would cruise around dumping large amounts of power into randomly selected pods.'
'It's done with a flip of the third joint of the tentacle on the down beat.'
'...for months Grantline bores had dug into the cliff.'
'I hope all those other cars are on automatic,' he said anxiously.
'It’s smart enough to go wrong in very complicated ways, but not smart enough to help us find out what’s wrong.'
