Use the camera positioner to change the view angle.
The red ball is the camera.
Double-clicking in the gray field
restores its default position.
Scripts
To draw each frame, Vizzy
runs a script-- a sequence of steps. Each
script belongs to a cue in the
timeline, so you can associate the script with a certain section of
music.
The current cue is the one
starting at, or to the immediate left, of the current frame (the red
line in the timeline).
The 'Presets' tab gets you
started by putting a short script in the current cue.
(The
preset
can also be added to the cue script; choose this option in File >
Preferences.)
The cue window has 'save' and 'load' buttons that let you save and
load your own presets.
You can choose an icon for the saved preset to help remember
what it
looks like, using File > Use Frame as Icon.
The Cue Script tab lets you
arrange and adjust the script's steps.
Steps execute top to bottom. The selected step is
highlighted in blue.
'+' is a menu of
instructions you can add.
the green circle sets
the selected step to its default values (OR edits a group).
up and down arrows
move the selected step in the sequence.
the red circle turns the
selected step off. It stays off until turned back on.
'i' opens the value inspector, which lets you see
and set
variable values.
'X' deletes the selected
step.
The flippy triangles open to show adjustments that you can make.
Most widgets have tooltips (seen when the mouse floats over the
widget).
The selected step (or group) can be cut, copied, and pasted into
cues.
Instruction Groups
Script steps are collected into groups by selecting the top step and
typing apple-g (or from the
menu: Edit>Group). Continue typing apple-g until all the steps you want
have been added.
To ungroup, select a group and type apple-shift-G.
Clicking the green circle opens a group editor, for rearranging the
steps in a group.
Tweening
Tweening means moving
smoothly from one script to another. Vizzy does this in two ways:
either by fade out/fade in, or
morphing. which tries to
smoothly change the settings. They can be used seperately or
together.
Over the width of the current cue, tweening takes into account both the
current and the previous cue. Beyond the cue end, only the
current cue controls the rendering (until the next cue starts).
To try out a tween, create a cue and give it some width. Give it
a
preset script; give the previous cue a different one. Click the
"Fade" button.
If you drag the mouse over the width of the cue, you should see a Fade
Out/Fade In tween.
Morph tweening
For Morph tweening, Vizzy goes through the 2 scripts step by
step. If the two steps are of the same type (e.g. Adjust/Boost),
the resulting render will average their settings. The
camera settings are also averaged.
The Timeline controls for transferring scripts come in handy for
setting this up. Once you have a visual you like, transfer it to
an adjacent cue. Then in one of the cues, you can change the
settings-- just don't add or remove any instructions.
Note that morph tweening can't merge settings that are either on or
off. For example, if one script draws triangles and the next
draws rectangles, there is no way to morph between them. You can,
however, turn fade tweening on
also.
Tween Options (experimental)
This allows morph tweening to go back and forth over the width of the
cue, rather than just straight through. The exact path is
programmed using an interface similar to the Cue Script. Let me
know what you think.
More details of advanced scripting can be found on the Scripts page.
