In collaboration with scientists at NASA's Jet Propulsion Laboratory,
the Geometry Center staff created an interactive spacecraft design
tool called <B>Crafter</B>.  It is intended for creating relatively
simple models of spacecraft for use in mission animations;
Crafter's learning curve is orders of magnitude smaller than full blown
CAD packages.  Crafter is also scriptable in Tcl, making it easy to
integrate with other programs.
<p>

Given a palette of spacecraft pieces (truss, parabolic dish, cylinder,
etc.), the user builds a hierarchical, geometric structure.  Each part
is attached to the structure with a specified transformation,
consisting of a scale, a rotation and a translation.

Crafter uses Geomview to display the spacecraft, giving the user
complete control over viewpoint, lighting, and other appearance
properties.  This also makes it easy to incorporate spacecraft
designed with Crafter into other Geomview-based applications.
