Set up Bounding Box decoration

Description

Set up the bounding box decoration.

Usage

rgl.bbox( 
  xat=NULL, xlab=NULL, xunit=0, xlen=5, 
  yat=NULL, ylab=NULL, yunit=0, ylen=5,
  zat=NULL, zlab=NULL, zunit=0, zlen=5,
  marklen=15.0, marklen.rel=TRUE, expand=1, ...)
bbox3d(xat, yat, zat, expand=1.03, nticks=5, ...)

Arguments

xat,yat,zat vector specifying the tickmark positions
xlab,ylab,zlab character vector specifying the tickmark labeling
xunit,yunit,zunit value specifying the tick mark base for uniform tick mark layout
xlen,ylen,zlen value specifying the number of tickmarks
marklen value specifying the length of the tickmarks
marklen.rel logical, if TRUE tick mark length is calculated using 1/marklen * axis length, otherwise tick mark length is marklen in coordinate space
expand value specifying how much to expand the bounding box around the data
nticks suggested number of ticks to use on axes
... Material properties (or other rgl.bbox parameters in the case of bbox3d). See rgl.material for details.

Details

Three different types of tick mark layouts are possible. If at is not NULL, the ticks are set up at custom positions. If unit is not zero, it defines the tick mark base. If length is not zero, it specifies the number of ticks that are automatically specified. The first colour specifies the bounding box, while the second one specifies the tick mark and font colour.

bbox3d defaults to pretty locations for the axis labels and a slightly larger box, whereas rgl.bbox covers the exact range.

axes3d offers more flexibility in the specification of the axes, but they are static, unlike those drawn by rgl.bbox and bbox3d.

Value

This function is called for the side effect of setting the bounding box decoration. A shape ID is returned to allow rgl.pop to delete it.
