A macro could look like this
#------------------------------------------------------------------------
# a three dimensional block
define tblock { [
box ht $2 wid $1 color "gold" outlined "black" xslanted 0 yslanted 0 $3
box ht .2 wid $1 with .sw at last box .nw \
xslanted .2 yslanted 0 color "yellow" outlined "black"
box ht $2 wid .2 with .nw at 2nd last box .ne \
xslanted 0 yslanted .2 color "goldenrod" outlined "black"
] }
tblock(2, 1, "This is" "a three dimensional" "Box");
#----------------------------------------------------------------------
But needs more flexibility setting the [xy]slanted (e.g. additional argument)
and the colors, which is more complicated. It needs up to three different
colors, or one main color and the other two derived from that, like
green --> darkgreen --> lightgreen
I'm still searching a bug in the pic code.
After some boxes I get a
stdin:26: numeric overflow
I can work around by placing a
box invisible
at some places, but than the position moves as well , even with 'box invisible
wid .00001 ht .00001'
