Demonstrates combining time-varying data (discrete datatimes) with time-varying warp (continuous extrapolation).

Add -a (anyway) option: include stars even if there's no corresponding radial velocity record.

"vec"/"vecscale" control commands, and "vecvar" data command.

as constructed by hiprv2speck from Hipparcos catalog (1/1239) and
General Catalog of Radial Velocities (3/3213).

to yield a partiview-format table of stars with 3-d space velocities.

for his implementation of Chromatek stereo, which color-encodes by
distance from the camera.

from a kira data file.

Choose initial position to put Orion/Hyades/Pleiades in view.

Use new "kira tree" cmd.

Specify limited time range (0 .. 9.625) to demonstrate how it's done
and to evade the interpolation bug.

Recipe for constructing primbin16.out, taken from Piet's e-mail of 22 Dec 2000.
Use as in
   make -f primbin16.mk

Examples of new CM-node-ring-marker and particle tracking.
Replace nclump.cmap with one for use with the new nclump codes,
where nclump is positive for stars and negative for CM nodes and rings.
The new cmap uses the same colors for both, but it could be changed.

Add marker controls.

For coloring by number-of-particles-in-clump.
