1 Definition
A Data Type digitally representing the surface and relevant features of a 3D Object:
- Sensed from the real world for use in a Virtual Space, or
- Digitally generated, or
- A mixture of the two.
It may be rendered to be perceived as signals in the human-visible range (380 to 700 nm).
2 Functional Requirements
A 3D Model includes the Qualifier of the Data Type of which the Model is an instance.
A Model of a human is called Persona and may:
- Faithfully reproduce the visual appearance of the human.
- Have their visual appearance altered, compared to that of the human.
- Have an unrelated visual appearance.
- Display a presumptive Personal Status in speech, face, and gesture.
- Be driven by
- The movements of the human.
- A Process.
