    Bidirectional reflectance distribution function

    w:Bidirectional reflectance distribution function or BRDF is a 7D model containing geometry, textures and reflectance of the subject.

    The seven dimensions of the BRDF are as follows: 3 cartesian X,Y,Z and 2 for the entry angle and 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|]] 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.
