3d plot of earth with cut
...tity "Value" at various depths
> and latitudes in 3D.
The rgl package has a full sphere of the Earth with (obsolete) political
boundaries in example(persp3d). To cut it in half along the plane
through a given longitude (and that longitude + 180 deg), you could use
clipPlanes3d, or clipObj3d. For example,
library(rgl)
lat <- matrix(seq(90, -90, len = 50)*pi/180, 50, 50, byrow = TRUE)
long <- matrix(seq(-180, 180, len = 50)*pi/180, 50, 50)
r <- 6378.1 # radius of Earth in km
x <- r*cos(lat)*cos(long)
y <- r*cos(lat)*sin(long)
z <- r*sin(lat)

3d plot of earth with cut
Hello,
Could someone suggest a package/way to make a 3D raster plot of the Earth
(with continent boundaries), and then make a "cut" or "slice" of it such
that one can also visualize some scalar quantity as a function of the
Radius/Depth across that given slice ?
Formally, I would have a given, fixed longitude, and a list of vectors
{latitude, radius, Value}
that would show
