In vectools: Advanced Vector Toolkit

Description

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

Usage

## S3 method for class 'GeomArray'
vt3.proj(v, proj="xy", sort=TRUE, ...)

## S3 method for class 'Grid'
vt3.proj(v, proj="xy", ...)
## S3 method for class 'Line'
vt3.proj(v, proj="xy", ...)
## S3 method for class 'Point'
vt3.proj(v, proj="xy", ...)
## S3 method for class 'Polygon'
vt3.proj(v, proj="xy", ...)
## S3 method for class '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.
