explode
How far to "explode" the sectors in user units
shade
If > 0 and < 1, the proportion to reduce the
brightness of the sector color to get a better 3D effect.
Details
draw.tilted.sector displays a single 3D pie sector. It is probably
only useful when called from pie3D. The shade
argument proportionately reduces the brightness of the RGB color of
the sector to produce a top lighted effect.
If explode is zero, only the top and outer side of each
sector will be displayed. This will sometimes fix the problem of a pie with
one huge sector greater than 3*pi/2 that cannot otherwise be drawn.
