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.
Light stage
A w:light stage or light cage is equipment used for shape, texture, reflectance and motion capture often with structured light and a multi-camera setup. (Wikipedia)
