NAME
graffiti - draw lines on geomview objects
DESCRIPTION
Graffiti is a geomview module which allows you
to draw polygonal lines on objects in the geomview window. The
Graffiti panel has buttons labeled "Draw", "Undo", "Vertices Only",
and "Quit". To start drawing, press the Draw button. While the Draw
button is down, you may interactively draw a polygonal line with
vertices on objects in the geomview window; clicking the right
mouse button on any object in the geomview window will cause a
vertex to be added to the line. Throughout the drawing process, the
initial point (the "tail") of the line is shown in a small box, and
the last point (the "head") is shown in a small pyramid. If you
click the right mouse button on the line's tail (the small box),
graffiti closes up the line segment. To end the line segment
without closing it up, just press the Draw button in the graffiti
window again.
Pressing the Undo button in the graffiti window while drawing a
line will undo the line's last vertex.
The Vertices Only button, when on, causes graffiti to only
recognize vertices in geomview objects. Use this button to force
your line's vertices to coincide with those of existing geomview
objects.
The Quit button exits graffiti.
BUGS
The cube and pyramid which indicate the tail and head
of the line are drawn with an absolute size which may or may not be
appropriate for all geomview objects.
The object created by graffiti is named "graffiti". If you quit
graffiti and start it up a second time in the same geomview
session, it uses this same name, thereby destroying the graffiti
object you created the first time.
Graffiti can create a maximum of 100 distinct polygonal lines
having at most a total of 1000 vertices.
