Spatial variable standards

Spatial Variables are a powerful feature allowing you to define location-dependent values. To support seamless interaction between independently developed objects it is necessary to follow standards for naming, types, content and sampling of spatial variables.

This article collects several community-proposed standards made with the goal that other users - instead of creating their own - reuse them for compatibility with other creations.

Physical Quantities

Temperature, pressure and other values can vary greatly between different locations. (i.e. temperature within fire vs. temperature of an ice cube)

Variable	Type	Unit	Interpretation	Sampling Recommendation	Notes	Proposed by/when
Temperature	float	K	temperature			TheAutopilot, 2025
Pressure	float	Pa	pressure			TheAutopilot, 2025
Gravity	float3	m/s²	global acceleration due to gravity			TheAutopilot, 2025
Force	float3	N	global force applied to all objects within the field			TheAutopilot, 2025
Density	float	kg/m³	density of the gas/liquid/solid at the sampled position			TheAutopilot, 2025
Velocity	float3	m/s	global velocity of the gas or liquid at the sampled position			TheAutopilot, 2025
