Usage

cylindersegment(rx = 1, ry = rx, from = pi, to = 3*pi/2, len = 1, 
                mid = c(0,0), angle = 0, dr = 0.01, col = "black", 
                delt = 1.0, ...)

Arguments

rx

horizontal radius of full cylinder.

ry

vertical radius of full cylinder.

from

start radius of segment, radians.

to

end radius of segment, radians.

len

cylinder length.

mid

midpoint of cylinder.

angle

rotation angle, degrees.

dr

size of segments, in radians, to draw top/bottom ellipse (decrease for smoother).

col

color of slice.

delt

increase factor, from left to right.

...

arguments passed to polygon function.

Details

When angle = 0 (the default), the cylindersegment is parallel to the x-axis.

rx and ry are the horizontal and vertical radiusses of the bordering ellipses. Here "horizontal" and "vertical" denote the position BEFORE rotation

if delt > 1, the width of the cylinder will increase from left to right.
