plotting points in geomview

[slevy]

Yes, you can plot points using either VECT or OFF objects.
OFF's are slightly simpler, and it's easier to attach colors to them.
E.g.:

VECT
3 3 0		# 3 vertices, 3 polylines, no colors

1 1 1		# each polyline has one vertex
0 0 0		# each polyline has no colors

.5 1.2 -1	# vertex
-.5 0 0		# vertex
0 .6 .5		# vertex

Or:

OFF
3 3 0		# 3 vertices, 3 "faces", don't care how many edges

.5 1.2 -1	# vertex #0
-.5 0 0		# vertex #1
0 .6 .5		# vertex #2

1  0		# First face contains one vertex, namely #0
1  1		# Second face has #1
1  2	.7 .3 0	# Third face has #2; color it orange

Setting the line width -- either interactively or via a prefix to the above
objects of e.g.

    appearance { linewidth 3 }

makes geomview plot small disks instead of single pixels for each point.
