gencyl2, gencyl3
Purpose
gencyl2, gencyl3
Create straight homogeneous generalized cylinder geometry object.
Syntax
Description
s3 = gencyl3
s2 = gencyl2
s3 = gencyl3(base)
s2 = gencyl2(base)
s3 = gencyl3(base,h)
s2 = gencyl2(base,h)
s3 = gencyl3(base,h,rat)
s2 = gencyl2(base,h,rat)
s3 = gencyl3(base,h,rat,...)
s2 = gencyl2(base,h,rat,...)
s3 = gencyl3 creates a solid straight homogenous generalized cylinder geometry
object s3, with a solid circle base surface, cylinder axis of length 1 along the z-axis,
and size of top surface equal to base surface. gencyl3 is a subclass of solid3.
s3 = gencyl3(base) creates a solid straight homogenous generalized cylinder
geometry object with base surface base.
s3 = gencyl3(base,h) also sets the height of the generalized cylinder to h.
s3 = gencyl3(base,h,rat) additionally specifies top surface with the scale factor
rat with respect to the origin, that is, all 2D points in the top plane are obtained by
multiplying the points in the base plane with rat.
The functions gencyl3/gencyl2 accept the following property/values:
