In YplantQMC: Plant Architectural Analysis with Yplant and QuasiMC

Description

Calculates the so-called 'silhouette area' of a projected plant. That is, the area of the (convex) outline of a projection of a plant onto a plane.

Usage

Silhouette(obj, azimuth = NA, altitude = NA)

Arguments

obj	Either a plant3d object, or a projectedplant3d object.
azimuth, altitude	Viewing azimuth and altitude (ignored if a projected plant is given as input).

Note

Not usually called by the user. Use instead, STARbar and projectplant. For the latter, see the option silhouette=TRUE.
