Sky Component Analysis#

Runs a sky component analysis that determines the percentage of direct light from the sky that reaches an analysis point compared to the light that reaches a point on an unobstructed horizontal surface.

The vertical sky component is calculated if the normal of the analysis point is on the horizontal plane representing a sample on a vertical surface and the sky type is set to S01_CIEStandardOvercastSky. As defined by the UK Building Research Establishment (BRE).

This analysis will take material transparency into consideration and reduce the sky component by the transmittance of the mesh faces that the rays pass through.

Inputs

Name Nickname Description Type
Run R Run this component. Boolean
Scene S Scene containing scene objects i.e. geometry groups, lights and materials. Scene
Scene Objects O Objects that will be added to the scene. These can be either materials, lights or geometry groups. SceneObject
Analysis Points P The analysis points to measure the sky component at. AnalysisPoint
Sky Type S The type of sky to run the analysis with. This analysis supports S01_CIEStandardOvercastSky and S05_CIEStandardUniformSky. String
