These diagrams often show a cubic form from which the architects will list a certain amount of operations driven by programmatic, climatic, or urbanistic purposes. Architecture is thus conceived as a original volume (maybe the reminiscence of an older paradigm) that saw itself more or less geometrically modified to achieve another volume.

Parametric design is a process based on algorithmic thinking that enables the expression of parameters and rules that, together, define, encode and clarify the relationship between design intent and design response.
Parametric design is a paradigm in design where the relationship between elements are used to manipulate and inform the design of complex geometries and structures.
The term 'Parametric' originates from mathematics (Parametric equation) and refers to the use of certain parameters or variables that can be edited to manipulate or alter the end result of an equation or system. Parametric design is not a new concept and has always formed a part of architecture and design. The consideration of changing forces such as climate, setting, culture, and use has always formed part of the design process
It seems that the diagrams at the very top of this thread are all singular representations of a parametric design process.
