BuildVisibilityGraph

Summary
Builds graph based on grid and calculates shortest visibility paths between all-to-all points.
Input parameters
Geometry Geometry from "PrepareGeometry" component.
VantagePoints Vantage Points.
Elements Specifies additional obstacle Revit elements (e.g. furniture) which are not by default included into analysis (See "PrepareGeometry" component).
View3D 3D View where input elements are visible.
ViewHeight Allows to control height value of VantagePoints in Grid. Default value is 1.6m.
LinkSize Allows to control the value under which two points in grid are assumed to be connected. Useful in case of stairs or gaps between rooms. Default value is 0.6m.
UseLinkSize Switch usage of LinkSize parameter on and off.
GPU Defines if GPU acceleration is switched on.
Returns
VisibilityGraph Calculated visibility graph and shortest paths.
Time Computation time.
