Movement and position control
Position control
Pan/tilt control
Important note: Mouse vs. touch devices for position control: In order to obtain the maximum
resolution for fixture pan/tilt positions, the pan/tilt grid implements a special interpretation of normal
mouse commands so the virtual size of the grid may be extended to a maximum size of 65536 x
65536 (representing full 16 bit pan/tilt resolution). The special interpretation involves a
programmatically reset of the mouse cursor position each time the mouse is moved. This approach
does not t work very well with touch devices where the cursor position (e.g. the users finger) cannot
be reset by LJ.
To make the position grid work with touch devices, select Preferences -> Left-Click Mode -> Touch
from the position control menu. To switch back to normal mouse mode, select Preferences -> Left-
Click Mode -> Mouse. Note that touch mode, can also be used with a mouse device - a touch device
is not a requirement for using touch mode. For more details on touch control, see below.
Typical pan/tilt position control
The picture shows a typical position control with pan/tilt control for fixtures such as scanners with a
mirror, or moving yoke fixtures. The primary control is the position grid. The dot represents the
absolute pan and tilt position of the mirror or yoke.
Mspeed control
Some fixture profiles implement an extra 'speed' control on the position control. The exact function of
the speed parameter depends entirely on the fixture itself, different fixtures may use the parameter in
different ways (e.g. slow or fast at low values).
Adjusting the position of one or more fixtures
To adjust the position of one or more fixtures, select the fixtures, then in the grid left-click and drag
the white dot to the desired position.
