Recipes for dynamics
The
number of controls and possibilities may be experienced as confusing. In this
chapter we
will explain what typical combinations of settings will result in what type of dynamics. Please
be aware that the number of combinations are quite high and
we can only explain a few of them here. You need to text the best
'recipe' yourself. The following controls are important to use with great
care: These are the basic choices you need to make before
attempting to randomly change these parameters: 1. You mainly want to use a tethered
camera, booth cam or web cam pictures When this is your preferred interaction with the
audience you should not activate to revert the flying path. The flying path
will always start from a full page preview, then fly towards the
mosaic. An initial mosaic needs to be made prior to starting the dynamics. The
application will always try to match the new picture with the mosaic;
and in some cases this will result in pictures having some kind of preferred
landing spot in the mosaic. The reason for this landing spot is because the
colour of the booth (etc) picture is best represented at that spot in the
mosaic. 2. You want to fully use
transparency and gradually build the source picture
With this preference setting you should first use a
valid transparent picture (.PNG format) where the alpha channel is properly
made. The transparency settings should be either 'at
start' or 'at end'. When you want to build a
source picture from an empty canvas you should also activate the option to 'Clear'
the mosaic after creation (with the background colour).
In this case the initial mosaic is fully wiped out and replaced by the
background colour. The mosaic tiles however are still in it's
memory. Some rules of
thumb
Scenario
builder
This is an experimental feature to quickly create the
correct flying, snapshot and transparency settings. The settings of these can
sometimes be confusing to cater for the several options. The scenario builder is
not foolproof, you always need to check if the show is really as you want it
to be. The scenario builder has 6 different controls to set.
Some controls are dependent, so if one is set, another may get locked with a
preset selection. These are the different settings for each
scenario aspect. The settings of the scenario builder will not interact
with the other settings of the GUI, but only between each other (like explained
above). When you are satisfied with the settings, you must use the 'Create scenario' button to synchronise the builder
settings with the other (normal) GUI settings, and save these as a normal
project file. Only when you have saved as a project file all settings between
the builder and the rest is synced. You can now use the
project files for easy retrieval of the
builder settings. When you save the scenario also the current selections
(checkboxes) of the source and commercial files are stored. In case you
are opening and loading an existing project you should ensure that also the
pictures are available. It will not keep the selections by name, only by sequence
in the overview. So, adding new pictures after having saved a project
might lead to different values from the project
saved settings!
The mosaic creation will continue until the commercial starts, after
which a new mosaic is created from the source picture of the checked source
list. This setting will generally lead to a continuously realistic mosaic
impression.
The mosaic matching engine will only affect the initial mosaic,
and has no influence of the placement of the new snapshots. A nice effect could
be to start with a full random picture (engine 'Full randomization') and then
let the mosaic rebuild itself with new pictures from either the library or booth
(etc) snapshots.
Transparent pictures can be used (line .PNG files). The
options for transparency are fully used: 'No
transparency' (so basically discarding the alpha channel of the .PNG
file), or 'Transparency at start' (where the picture
already is made transparent where it needs to be when shown full screen) or
'Transparency at the end' (where the final placement
step is to make these parts transparent).
The flying direction now depends on the tile sources:
