r - Maximum values for line width (lwd) argument in RGL -

i can't figure out why there apparent maximum limit rgl argument rgl function in r. segments3d() cannot apparently back upwards line widths on around 6-8, constraint doesn't seem documented. illustration demonstrates:

require(rgl) x = rep(sample(1:10,50, rep=t), each=2) y = rep(sample(1:10,50, rep=t), each=2) z = rep(sample(1:10,50, rep=t), each=2) z[(1:50)*2] = 0 d = data.frame(x=x, y=y, z=z) segments3d(d, lwd=2) segments3d(d, lwd=8) segments3d(d, lwd=50)

any view on why happening?

this not answer, demonstration of get.

segments3d(d, lwd=8)

segments3d(d, lwd=50)

r rgl
