Does a honeybee implementation of the Radiance ‘mist’ primitive exist?
Need for a Volume Based Radiance Primitive
As part of my PhD research, I am using honeybee-legacy as a front end to the Radiance engine in an exploratory attempt to simulate radiation propagation in indoor farms. The farms grow their crop with total lamp sourced radiation or through a combination of lamp sourced and solar radiation. Academic literature has provided various methods of simulating the optical properties of plant canopies as either volumes(1) or distributed surfaces(2), and I am exploring both research pathways. However, all honeybee implemented Radiance primitives only allows implementation of optical properties on surfaces. Only the Radiance “mist” primitive allows implementation of volume extinguishing coefficients.
Honeybee Discourse Question
In this context, Honeybee appears to fully have the capability to act as a front end when simulating the crop as a distributed surface. However, to my yet nascent understanding, I have not found a honeybee script that implements the Radiance “mist” primitive(3). Am I looking in the wrong places? If so, could someone kindly point me in the right direction?
