projectplant: Project plant coordinates onto a viewing plane
In YplantQMC: Plant architectural analysis with Yplant and QuasiMC.

Description Usage Arguments Value Author(s) See Also Examples

Transform all leaf edge coordinates onto a viewplane coordinate system, with the 'z' axis pointing toward the viewer.

projectplant(plant, azimuth, altitude)
## S3 method for class 'projectedplant3d'
plot(x, silhouette = FALSE, xlim = NULL, ylim = NULL, 
leaffill = TRUE, leafcol = "forestgreen", zerocenter = FALSE, xlab = "X", ylab = "Y", ...)

`plant`	Object of class 'plant3d' (see `constructplant`.
`azimuth,altitude`	Azimuth and altitude from which plant is viewed.
`x`	Object of class 'projectedplant3d'.
`silhouette`	Add a 2D convex hull (see `Silhouette`).
`xlim,ylim`	Limits for the X and Y axes.
`leaffill`	If TRUE, fills leaves with green stuff.
`leafcol`	If leaffill=TRUE, the color of the leaves.
`zerocenter`	Whether to shift the plant to X=0 and Y=0.
`xlab,ylab`	Labels for X and Y axes
`...`	Further parameters passed to plot() (but ignored for print).

Returns an object of class 'projectedplant3d', with components:

`leaves`	A list of matrices with the coordinates of the leaf edges. Each matrix has columns VX,VY and VZ, which are the viewplane coordinates (with the Z axis pointing toward the viewer).
`viewbound`	List of min and max values of coordinates (minx, maxx, miny, etc.).
`viewangle`	Azimuth and altitude used for projection.

# The 2D convex hull is also plotted (the 'silhouette'), 
# and the area of the hull is printed on the graph.
