draw.tilted.sector: Display a 3D pie sector

Description

Displays a 3D pie sector.

Usage

draw.tilted.sector(x=0,y=0,edges=NA,radius=1,height=0.1,theta=pi/6,
  start=0,end=pi*2,border=par("fg"),col=par("bg"),explode=0,shade=0.8)

Arguments

x,y

Position of the center of the pie sector in user units

edges

Number of edges to draw a complete ellipse

radius

the radius of the pie in user units

height

the height of the pie in user units

theta

The angle of viewing in radians

start

Starting angle of the sector

end

Ending angle of the sector

border

The color of the sector border lines

col

Color of the sector

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.

Value

The bisector of the pie sector in radians.

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.
