Those guys that wanted Laz in GMT lead me to find this about ps file sizes when doing plot3d. In the case of the laz file (~2e^6 points) the plotd3 ps was about 411 MB. Quite big.
With a synthetic case these two have a bout the same size (~25 kB) but curiously with 2e^6 points the
plot3d
ps had ~50 Mb whilst theplot
had ~70 Mbbut the big difference comes when use perspective other then vertical. It only take to change
view=(181,80)
toview=(181,90)
and the file size grows to 41.5 kB (with the 2e^6 points it was 411 MB).The reason seems to be that now each point is plotted with what seems a kindof rotation matrix that uses 12 decimal places and where all but the last coefficient is repeated thru out the file
