antiview [options] input_files
Display OFF files in an interactive viewer.
- input_files
- input files in OFF format, or if not given the program reads from standard input
- -h
- program help
- -v <rad>
- radius of vertex spheres, or 'b' to have radius of balls
in the first file of the maximum size without overlap (default:
ball_rad/15)
- -e <rad>
- radius of edge cylinders (default: vertex_rad/1.5)
- -V <col>
- default vertex colour, in form r_val,g_val,b_val (values 0.0-1.0,
or 0-255) or hex xFFFFFF (default: 1.0,0.5,0.0)
- -E <col>
- colour for edges, in form r_val,g_val,b_val
(values 0.0-1.0, or 0-255) or hex xFFFFFF,
x to hide implicit edges
(default: 0.8,0.6,0.8)
- -F <col>
- default face colour, in form r_val,g_val,b_val (values 0.0-1.0,
or 0-255) or hex xFFFFFF (default: 0.8,0.9,0.9)
- -x <elems>
- hide elements. The element string can include v, e and f
to hide vertices, edges and faces
- -n <elems>
- show element index number labels. The element string can
include v, e and f to label vertices, edges and faces
- -m <map>
- map colour indexes into colour values, map is given as
'file,elems,conv_type'
for colour map file, conv_type is (default 3)
- 1 - convert all, use only colours in the colour map file
- 2 - convert all, use colour scheme for index numbers not listed
in the colour map file
- 3 - convert only the index numbers listed in the colour map file
elements to map are v, e or f
- -w <width>
- width of sphere containing points (default: calculated)
- -I <dist>
- maximum distance from origin for viewable points (default: ignored)
Scene Options
- -D <dist>
- distance to camera
- -C <cent>
- centre of points, in form x_val,y_val,z_val (default: calculated)
- -L <look>
- point to look at, in form x_val,y_val,z_val (default: points centre)
- -R <rot>
- rotate about axes through centre of points, in
form x_val,y_val,z_val (degrees)
- -B <col>
- background colour, in form r_val,g_val,b_val
(values 0.0-1.0, or 0-255) or hex xFFFFFF
There are four main viewing control modes - rotation (default), drag,
zoom, slice. Select a different mode with the following
keys, or right-click on the window and select from the menu
Click and drag on the window with the mouse to move the model,
or use the arrow keys. The zoom and slice are controlled by
forward and backward dragging, or the up and down arrow keys.
Menu Items
- r - Rotate
- turn the model about its centre
- d - Drag
- drag the model around the screen
- z - Zoom
- Zoom in or out
- s - Spin Control
- set or stop the model spinning
- S - Slice
- Slice into the model. There is a slicing plane just in front
of the screen which can be moved forward and backwards. It
may take a couple of forward drags with the mouse (or hold
down the the up-arrow key for a few seconds) until this
plane reaches the model and starts slicing into it.
