plot.projectedplant3d: Project plant coordinates onto a viewing plane

Description

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

Usage

"plot"(x, silhouette = FALSE, xlim = NULL, ylim = NULL, leaffill = TRUE, leafcol = "forestgreen", zerocenter = FALSE, xlab = "X", ylab = "Y", ...)
"print"(x, ...)
projectplant(plant, azimuth, altitude)

Arguments

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

plant

Object of class 'plant3d' (see constructplant.

azimuth, altitude

Azimuth and altitude from which plant is viewed.

...

Further parameters passed to plot() (but ignored for print).

Value

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.

Examples

# View a plant from above.
# The 2D convex hull is also plotted (the 'silhouette'), 
# and the area of the hull is printed on the graph.
topview <- projectplant(pilularis, altitude=90, azimuth=180)
plot(topview, leaffil=TRUE, silhouette=TRUE)
