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", "Ver-
tices Only", and "Quit". To start drawing, press the Draw
button. While the Draw button is down, you may interac-
tively 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.
