Function

What are functions

A function is the purpose of a type of building. The term function comes from urban planning jargon, when dealing with zoning plans.

How do functions relate to the Tygron Platform

Functions are the blueprints of Constructions in the 3D world. They describe the purpose and properties of Constructions. A Function also defines which 3D model is placed in the 3D world. A Function is effectively a "type of Construction".

The properties associated with a Function are known as Function Values

Each Construction in a Project has a Function defining what kind of Construction it is. Constructions with the same Function may have different locations, different heights, and different owners. But Constructions with the same Function will have the same set of properties defining their economic, environmental, and spatial effect.

Additionally, Functions can also be used as definitions for actions. When a Function is used as an Action, the Action will be the creation of a new Construction, the Function of which is the Function which is used as Action. Some properties of the Function, such as the minimum, maximum, and default amount of floors, also affect how a Stakeholder can enact their action.

The Tygron Platform contains several hundred Functions.

Function values

Main article: Function Value

Functions are composed of a collection of properties called Function Values. These form the actual numeric definitions which are applied on a Construction which is set to be of a certain Function. In principle, when such a value of a Construction is required for a calculation, the value set in the Function is used. However, a Construction can have a Function Value overridden for itself. If the Construction in consideration for a calculation has an overridden Function Value, that overridden value will be used instead.

A complete list of all available Function Values can be found on the Function Values page.

Function Categories

The function selection window. This will appear whenever you need to a select a function.

Functions are divided into Function Categories. Where a Function itself may be "Old Warehouses", such a Function may belong to a Function Category "Industry". This categorization helps when trying to select a specific Function among the full collection of Functions. It also makes it easier to query Constructions in a Project but filtering on the purposes of the Construction. Rather than creating individual queries for each Function which matches a broad usage for Constructions, a single query for a Function Category can be used.

Functions are always part of at least one Category, but can also be part of multiple functions. An example is a Function for a Construction with shops at a bottom floor, but residences on floors above it. Or flats which contain a mix of both social and luxury housing. In these cases, the Function's Categories each have a respective weight. The Construction will be considered wholly of the specified Function, but the Construction will be considered "divided up" between the Categories when querying, for example, their floor size.

Categories:

Currently the Tygron Platform distinguishes the following Function Categories:

Category	TQL Term	Combinable	Description
Affordable housing	SOCIAL	yes
Agriculture	AGRICULTURE
Bridge	BRIDGE
Education	EDUCATION	yes
Gardens	GARDEN
Healthcare	HEALTHCARE	yes
Industry	INDUSTRY	yes
Intersection	INTERSECTION
Leisure	LEISURE
Market housing	NORMAL	yes
Nature	NATURE
Offices	OFFICES	yes

Senior housing	SENIOR	yes
Shops and restaurants	SHOPPING	yes
Squares	PAVED_AREA
Student housing	STUDENT	yes
Top market housing	LUXE	yes
Underground	UNDERGROUND

Regions

The region selector, to filter the available functions.

To further help with finding the appropriate Function, they are also divided into regions. Based on the location of the Project, the region for the Project is set automatically. Some Functions are only available in certain regions. This is based on what region of the world the Function would be most appropriate for.

When selecting a Function, it is possible to change the region of the Project to gain access to the Functions of other regions. It is possible to Mix Functions of various regions freely.

Regions:

Currently the Tygron Platform distinguishes the following regions:

• Africa
• Asia
• North America
• Northwestern Europe
• Other
