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.
