NAME
|
genworm - generate a RADIANCE description of a functional worm |
SYNOPSIS
|
genworm mat name 'x(t)' 'y(t)' 'z(t)' 'r(t)' nseg [
-e expr ][ -f file ] |
DESCRIPTION
|
Genworm produces a RADIANCE scene description of a
worm defined by the parametric equations x(t), y(t),
z(t), and r(t) (the radius). T will vary
from 0 to 1 in steps of 1/nseg. The surface will be
composed of nseg cones or cylinders and nseg+1
spheres. The expressions are of the same type used in
RADIANCE function files. Auxiliary expressions and/or files
may be specified in any number of -e and -f
options. |
EXAMPLE
|
genworm yellow banana '0' '5*sin(t)' '5*cos(t)'
'.4-(.5-t)*(.5-t)' 20 |

BUGS
|
Since the worm is constructed of intersecting surfaces, only
opaque materials should be used with this object. Also, a
worm cannot double back inside itself without making a
mess. |
