Description

Functions for Mapping 3D GeomObject(s) to 2D GeomObject(s).

Usage

# S3 method for GeomArray
vt3.proj(v, proj="xy", sort=TRUE, …)
# S3 method for Grid
vt3.proj(v, proj="xy", …)
# S3 method for Line
vt3.proj(v, proj="xy", …)
# S3 method for Point
vt3.proj(v, proj="xy", …)
# S3 method for Polygon
vt3.proj(v, proj="xy", …)
# S3 method for Text
vt3.proj(v, proj="xy", …)

Arguments

v

A 3D GeomObject.

proj

String, including "xy", "xz" or "yz"

sort

Logical, if true, sort the GeomArray, which is necessary to plot the corresponding 2D-based arrays correctly.

…

Ignored.

Value

A 2D GeomObject.

Note that plotting a 3D object, automatically projects it.
