cone2, cone3
Purpose
cone2, cone3
Construction function for circular cone geometry object.
Syntax
Description
c3 = cone3
c2 = cone2
c3 = cone3(r,h)
c2 = cone2(r,h)
c3 = cone3(r,h,ang)
c2 = cone2(r,h,ang)
c3 = cone3(r,h,ang,...)
c2 = cone2(r,h,ang,...)
c3 = cone3 creates a solid circular cone geometry object with bottom radius and
height equal to 1, top radius equal to 0.5, and the center of the bottom at the origin.
cone3 is a subclass of econe3.
c3 = cone3(r,h) creates a solid circular cone geometry object, with bottom radius
r, height h, and top radius r/2.
c3 = cone3(r,h,ang) creates a solid circular cone geometry object, with bottom
radius r, height h, and the angle ang between the local z-axis and a generator of the
conical surface. ang is given in radians in the interval [0,pi/2).
The functions cone3/cone2 accept the following property/values:
TABLE 1-9: VALID PROPERTY/VALUE PAIRS
PROPERTY VALUE DEFAULT DESCRIPTION
axis
Vector of
reals or cell
array of
strings
[0 0] Local z-axis of the object
const Cell array of {} Evaluation context for string inputs
strings
pos
Vector of [0 0] Position of the object
reals or cell

For more information on input arguments and properties see gencyl3.
c2 = cone2(...) creates a surface circular cone geometry object without bottom
and top faces, according to the arguments as described for cone3. cone2 is a
subclass of econe2.
