Upon initialization of the program, two graphics windows are opened, one for the color table and the other for data display. The display window initially contains a red bounding box. Command options are then printed to the terminal and user is prompted for drawing instructions:
THE INTERACTIVE OPTIONS ARE: ?, (l #), L, (t #), (T # #), I, +, - (x #) (y #) (z #) r (X #) (Y #) (Z #) (B(x,y,z)#), (E(x,y,z)#), S, R, F, C, c, s, b, g, n, p[#], d, D, w, Q, h USAGE AND MEANING: ? lists available thresholds l index# [index#...] add threshold to display list L draw current display list t index# reset so only this threshold is displayed T index# index# show thresholds between hi & lo I toggle thresholds INSIDE hi/lo or OUTSIDE hi/lo +(+++) display thresholds with consecutively increasing index# -(---) display thresholds with consecutively decreasing index# x int# absolute rotation around x-axis in degrees(int) y int# absolute rotation around y-axis in degrees(int) z int# absolute rotation around z-axis in degrees(int) r rotate_model X int# scale model in x Y int# scale model in y Z int# scale model in z B(x,y,z)int# begin display along (x,y,z) axis at # E(x,y,z)int# end display along (x,y,z)axis # S int# specular highlight control R resets display along axis to show all data F grid3name colortablename load new color file C toggles the clear flag c clears the display (no thresholds) s swaps buffers b toggles draw a box g toggles grid n toggles surface normal direction p draw all walls p# draw a wall: 1-top, 2-bottom, 3-east, 4-west, 5-north, 6-south d draw (implement the option) D draw a solid defined by T(isosurface + parts of walls) w dump image to a file Q QUIT h help enter desired manipulations then press return >>
List available thresholds with ?. Use l to select isosurfaces (available
number can be adjusted with r3.mkdspf) and L to display:
l 1 2 3 4 5
L
To select and display a single threshold (here: 2), use:
t 2
To select and display a range of thresholds (here: 3-5), use:
T 3 5
D
To draw a box, enter
p
the p# to plot a selected wall (here top wall):
p1
Tp draw a cut-off box, define it's position
Ex20
p
Here Ex20 defines the x coordinate of the end of the box.
In general - p draws a side of a box, E, B, define where that box starts or ends, so to make a fence diagram, the user draws sides of a series of boxes which have their starting (or ending) side shifting by a given interval. (this way the user can draw even more complex fence diagrams which have perpendicular fences, by using Ey or By). It is sufficient to use only E or B depending whether fence are drawn by using the end side or front side of a box).
To draw a fence, a sequence like this would be needed
Ex10
p5
Ex15
p5
Ex20
p5
Ex25
p5
or the same would be
Bx10
p6
Bx15
p6
Bx20
p6
The p is needed for the fence diagram, solids and boxes.
