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. This analysis only includes the direct relationship to the sky, use the daylight factor analysis if reflections and transparency need to be considered.

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).

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. The sky component analysis supports S01_CIEStandardOvercastSky, S05_CIEStandardUniformSky and S16_CIETraditionalOvercastSky. String
Visibility Mask M A visibility mask that controls which geometry is visible in this analysis. VisibilityMask
