NAME
aven - sophisticated cave viewer
SYNOPSIS
aven [--survey=SURVEY] [--print] SURVEY_FILE
DESCRIPTION
Aven displays processed cave surveys in a window and allows you to manipulate the view.
If SURVEY_FILE is an unprocessed survey data format which cavern can process, then aven
will run cavern on it, and if successful, display the processed data. If there are any
warnings and errors, it will show a log window with the output with clickable links to
open the affected file at the problematic line.
SURVEY_FILE can also be processed survey data - a Survex .3d file, a Compass .plt file or
a CMAP .sht file. It can also be a Survex .pos file or a CMP .una or .adj file, but for
these only stations are shown, not any legs (for .pos this is because the format only
records station positions). (All Survex programs which read .3d files can also
transparently handle these formats.)
On-Screen Indicators
There is an auto-resizing scale bar along the bottom of the screen which varies in length
as you zoom in or out. You can left-button drag on this to zoom, and right click gives a
menu to select units or hide the scale bar (to get it back go to the Control->Indicators
menu from the menu bar).
In the lower right corner is a compass indicator showing which way is North. You can drag
this to rotate the view; if while dragging you move the mouse outside the compass the view
snaps to 45° positions: N/NE/E/SE/S/SW/W/NW. Right click gives menu to change the view to
N/S/E/W, select units, or hide the compass (to get it back go to the Control->Indicators
menu from the menu bar).
Just to the left of the compass is clino indicator showing the angle of tilt. You can
drag this to tilt the view; if while dragging you move the mouse outside the clino the
view snaps to 90° positions: plan/elevation/inverted plan. Right click gives menu to
change the view to plan/elevation, select units, or hide the clino (to get it back go to
the Control->Indicators menu from the menu bar).
In the upper right is a colour key showing the correspondence between colour and depth (by
default - you can also colour by other criteria). Right click gives a menu to choose what
to colour by, select units, or hide the colour key (to get it back go to the
Control->Indicators menu from the menu bar).
Mouse Control
Using the mouse to move the cave will probably feel most natural. We suggest you try each
of these out after reading this section to get a feel for how they work.
If you hold down the right button then the view is panned when you move the mouse - it
effectively feels like you are dragging the cave around.
If you hold down the left button, then the view is rotated as you move left or right, and
zoomed as you move up and down. If you hold down Ctrl while dragging with the left mouse
button, then moving up and down instead tilts the view. Tilt goes 180 degrees from plan
view through elevation view to a view from directly below (upside down plan) - aven
deliberately doesn't allow going beyond horizontal into an inverted view.
If your mouse has a middle button then holding it down and moving the mouse up and down
tilts the cave. Moving the mouse left and right has no effect.
And if you have a scrollwheel, this can be used to zoom in/out.
By default the mouse moves the cave, but if you press Ctrl-R, then the mouse will move the
viewpoint instead (i.e. everything will go in the opposite direction). Apparently this
feels more natural to some people.
Keyboard Control
As with mouse controls, a little experimentation should give a better understanding of how
these work.
All keyboard shortcuts have a corresponding menu items which should show the keyboard
shortcut - this provides a way within the application to see the keyboard shortcut for a
particular action.
Delete is useful if you get lost! It resets the scale, position, and rotation speed, so
that the cave returns to the centre of the screen. There are also keyboard controls to
use
P and L select Plan and eLevation respectively. Changing between plan to elevation is
animated to help you see where you are and how things relate. This animation is
automatically disabled on slow machines to avoid user frustration. You can force skipping
the animation by pressing the key again during it, so a double press will always take you
there quickly.
Space toggles on and off automatic rotation about a vertical axis through the current
centre point (which is moved by panning the view or by selecting a station or survey). R
toggles the direction of auto-rotation. The speed of auto-rotation can be controlled by Z
and X.
Crosses and/or labels can be displayed at survey stations. Ctrl-X toggles crosses and
Ctrl-N station names. Ctrl-L toggles the display of survey legs and Ctrl-F of surface
survey legs.
Ctrl-G toggles display of an auto-sizing grid.
Ctrl-B toggles display of a bounding box.
O toggles display of non-overlapping/all names. For a large survey turning on overlapping
names will make update rather slow.
Holding down Shift accelerates all the following movement keys:
The cursor keys pan the survey view (like dragging with the right mouse button).
Ctrl plus cursor keys rotate and tilt (like the mouse left button with Ctrl held down).
C/V do the same as Ctrl plus cursor left/right, while Apostrophe ', and Slash / do the
same as Ctrl plus cursor up/down.
[ and ] zoom out and in respectively.
