VIEWER3 - VIEWER for 3-dimensional model ",
viewer3 [parameters] < hzfile
Optional Parameters: ",
hue=1 =1 for hue =0 for black/white
q=-0.6,0.06,-0.06,0.8 define the quaternion
tbs=0.8 the lager the trackball size is, the slower it rotates
verbose=0 =1 print some useful information
rayfile=NULL ray path file to read in
wffile=NULL wavefront file to read in
sttfile=NULL surface traveltime file to read in
Menu: The rightmost mouse button, with cursor placed on the graphics
window activates the following menu:
Quit: quits the application
Full Screen: expands graphics window to full screen
White/Color Rays: selects colored (default) or white rays ",
Plot Rays: show the rays (default: off)
Surface Traveltimes: show surface traveltimes (default: off)
Wired or Solid WFs: style of wavefront display wireframe (default)
or solid ",
Plot Wavefronts: turn on wavefronts default: off
TRI or TETRA or LAYER or HORZ: toggles display from wireframe
triangulated horizons, to wireframe tetrahedra,
to solid layers, to solid horizons
Layer1: toggle layer on or off (default is on)
....
Notes:
In general, the tetrahedra model should be generated by tetramod
(tetrahedra modle builder) which outputs a file called hzfile, so
that viewer3 can read input from stdin.
If, in addition, you have 3D raypath information (rayfile), wavefronts
(wffile) and surface traveltimes (sttfile), typically generated by
sutetraray (tetrahedral wavefront construction ray tracing),
then rays, wavefronts and surface traveltimes can be displayed as well
as the model.
The plot may be rotated by depressing the leftmost mouse button
and dragging the cursor in the desired direction of rotation. The speed
of rotation is controlled by the speed of the cursor.
The plot may be rescaled by depressing the shift key, while also
depressing and dragging the cursor up or down on the display window.
