rgl.bbox {rgl} | R Documentation |
Set up the bounding box decoration.
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, ...)
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/ |
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 |
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
.
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.
