= Appearance and voice theft =
Appearance is thieved with [[digital look-alikes]] and voice is thieved with [[digital sound-alikes]]. These are new and very extreme forms of identity theft. Ban covert modeling and possession and doing anything with a model of a human's voice, but don't ban the [[Adequate Porn Watcher AI (concept)]].

= Bidirectional reflectance distribution function =

[[File:BRDF_Diagram.svg|thumb|right|300px|Diagram showing vectors used to define the [[w:Bidirectional reflectance distribution function|w:BRDF]].]]

{{Q|The '''bidirectional reflectance distribution function''' ('''BRDF''') is a function of four real variables that defines how light is reflected at an [[w:Opacity (optics)|opaque]] surface. It is employed in the [[w:optics|optics]] of real-world light, in [[w:computer graphics|computer graphics]] algorithms, and in [[w:computer vision|computer vision]] algorithms.|Wikipedia|[[w:bidirectional reflectance distribution function|BRDF]]}}

A BRDF model is a 7 dimensional model containing geometry, textures and reflectance of the subject. 

The seven dimensions of the BRDF model are as follows: 
* 3 cartesian X,Y,Z 
* 2 for the entry angle
* 2 for the exit angle of the light.

= Covert modeling =

'''Covert modeling''' refers to both covertly modeling aspects of a subject i.e. without express consent.

Main known cases are
* Covertly modeling the '''human appearance''' into 7-dimensional [[#Bidirectional reflectance distribution function|Bidirectional reflectance distribution function]] model or other type of model.
* Covertly modeling the '''human voice'''
There is work ongoing to model e.g. '''human's style of writing''', but this is probably not as drastic a threat as the covert modeling of appearance and of voice.

= Digital look-alike =
When the [[#No camera|camera does not exist]], but the subject being imaged with a simulation of a (movie) camera deceives the watcher to believe it is some living or dead person it is a '''[[digital look-alikes|digital look-alike]]'''. Alternative term is '''''look-like-anyone-machine'''''.

Saying "digital look-alike of X" would imply possession, but "digital look-alike made of X" is more suited, unless the target really is in possession of it.

= No camera =
'''No camera''' ('''!''') refers to the fact that a simulation of a camera is not a camera. If people realize the differences, and thus the different restrictions by many types of laws e.g. physics, physiology. Analogously see [[#No microphone]], usually seen below this entry.

'''No microphone''' is needed when using synthetic voices as you just model them, without needing to capture. Analogously see the entry [[#No camera]], usually seen above this entry.

= Reflectance capture =
'''Reflectance capture''' is made by measuring the reflected light for each incoming light direction and every exit direction, often with many different wavelengths. Using polarisers allow to separately capture the specular and the diffuse reflected light.
