NAME

cyl - create an open-ended, truncated right cylinder

SYNOPSIS

cyl v1 rad v2

DESCRIPTION

Create a truncated right cylinder of radius rad using the current material, starting at the named vertex v1 and continuing to v2. The ends will be open, but may be capped using the ring entity if desired.

The surface normal will usually be directed outward, but may be directed inward by giving a negative value for rad. A zero radius is illegal, and v1 cannot equal v2.

EXAMPLE 

# A stylus with one rounded and one pointed end
o stylus
	v vtip0 =
		p 0 0 0
	v vtip1 =
		p 0 0 .005
	v vend =
		p 0 0 .05
	cyl vtip1 .0015 vend
	sph vend .0015
	cone vtip0 0 vtip1 .0015
