Martin Lee – Parametric Solar Shading Progress
Solar Shading Derivation
For my solar shading paneling system, the form and its derivation, based on the sun's location can most simply described by taking the height of the sun in Rhino & Grasshopper to cause an exterior panel geometry to get smaller as the sun gets higher in the sky. The more extensive, in depth is as follows - Apply simple rectangular geometry -> Divide surface vertically -> Apply squares to given points -> Move newly derived square grid up 1 unit -> Change squares to a triangle geometry -> Create ruled surface between 2 geometries -> Use given Heliotrope script to create a theoretical sun in GH // Rhino -> Measure the height of the sun using vector point and distance components -> Manipulate measured data of sun's height in a variety of ways so that the value is applicable and to scale for the triangle panel sizing -> Write proportional factoring equation for triangle panel size -> Plug manipulated values from previous derivation above into the proportional factoring component -> Use this data and result of component to scale triangle geometry
