Animation Controls
Besides creating an
animation, there are a number of controls for the animation system
that you need to set, such as the length, and the type of time code and
video system to use. This tutorial shows you the animation controls that
are available in Realsoft 3D.
Animation length
You can change the total length of your animation at any time using the frame count field in the animation
window.
Animation consisting of 150 frames.
To add new frames
to your animation (increase the length), enter the desired value in the
field and press the Enter key. A dialog appears asking if you want
to scale the timelines for any animated objects.
To add new frames
without affecting the length of any currently defined animations, select
No (do not scale the time lines). If you want to scale the existing animation
timelines to include the new frames being added, select Yes.
You remove frames
(shorten) from an animation by the same process as adding frames: type
a new length into the frame count field and press Enter. However, be aware
that if you decrease the total number of frames to less than the length
of any particular choreograph, and do not scale the timelines, such choreographs
will be affected. Again, you always have the option of using the Time
Lines tab of the choreography editor to make adjustments.
Setting the time code and video system
Before you start an
animation project, you should set the type of time system and video system
to use. To access the Time code settings, open the Preferences window from the main
menu ('File/Preferences/Window'), and click the 'Animation' tab.
Selecting time units
For the Time System, you have three options:
-
Frames (default). Time
values are in units of frames. The number of frames needed to comprise
one second depends on the video system setting.
-
Real Time. Time values
are in units of minutes, seconds, and frames. This is the standard time
code system used by video equipment, and is also dependent on the video
system setting.
-
Seconds. Time values
are shown in units of seconds. This system may be more natural if you are
doing physical simulations, or are using physical formulas within an animation.
You can change the time system at any time. The user interface automatically
adapts to the selected time system. For example, if you select the time
code value, three fields (minutes, seconds, frames) are used to show animation
timing. Also, changing the time system does not affect any existing motion
definitions. The time system only affects how the user interface displays
time attributes.
The time line showing real time units
The video system can be selected from the Animation Settings
window. You can find this window below the select window in the default startup
project, and in the Windows pull down menu.
Suspending and resuming animation rendering
Realsoft 3D allows you
to start and stop the rendering of a project or scene at any time, without
losing the work that has been performed. This is quite useful when rendering
long animation sequences.
Assume that you have
started rendering a long animation, say 1200 frames, and you want to stop
the rendering for some reason, and then resume it again later from the
point at which it was stopped.
The controls for
doing this can be accessed either from the file rendering window, or from
the main menu.
To stop rendering
an animation, press the Stop button on the file rendering window, or
make the following selection from the main menu: Animation/Playback/Stop.
Then use File/Save As to save the entire project. The current time is
saved with the project. You can then load the project again at any time,
and click the Render Animation button on the file rendering window to
continue rendering the project.
Defining project-specific animation settings
Every time you create
a new animation, you have to define a number of project-specific animation
options. For example, you have to decide whether to use motion blur. You
might also want to use field rendering. These options can be defined through
the Animation Settings window. You can find this window below the select
window in the default startup project.
Project-specific
animation settings
If you select the
Motion Blur option, you also need to specify the desired sample count
in the Samples field. The higher the value, the better the quality of
the generated motion blur (Note that higher values will affect your rendering
time).
If field rendering
or motion blur is activated, the animation playback window will show gadgets
that allow you to control and select time in units of fields and motion
blur samples, as well as frames. This allows you, for example, to access
the time line at finer resolutions, such as Frame=2, Field=odd, and Sample=3,
and then, for instance, modify an object to create a key frame.
