Frame interval in real time

User Interface, Data Forms
OrcaFlex needs to know how fast to play the replay. This data item specifies the interval, in real time, between each
replay frame, assuming a target replay speed of 100%. If the target replay speed is, say 200%, then the interval
between frames will be half this value, and so on.
Replay Sections
You can specify any number of replay sections. For each replay section you must also specify the following:
Replay Section Name
This is a descriptive name for the replay section. When the replay is running OrcaFlex displays a description of the
current frame in the message box on the status bar – this includes the replay section name. This description can also
be included in exported videos.
OrcaFlex File Name
The model to be used for this section – either a data file (.dat or .yml) or a simulation file (.sim).
Dynamics
This setting determines whether the replay section defines snapshots from a dynamic simulation or a static
configuration. If the file is a data file then the replay section will show the static configuration and so this data item
cannot be edited.
The custom replay displays static configurations for a data file by loading the file and then performing the static
calculation. This can be time consuming – static state simulation files can be used instead to avoid the overhead of
performing statics each time the replay is shown.
Simulation Time From, Simulation Time To
This specifies the period of the dynamic simulation covered by the replay section. These are OrcaFlex simulation
times for the specified simulation file of this replay section.
If the replay section is a static snapshot then these data items are not editable.
Number of Frames
This is the total number of frames in the replay section. If your custom replay is a series of static snapshots then you
would usually set this value to 1.
Included in Replay
This allows you to exclude certain sections from the replay. This may be useful while developing the custom replay
because it allows you to concentrate on particular replay sections.
View Parameter data
The following data items are only available when the specifies view parameters option is checked.
From View Parameters, To View Parameters
The view size, view centre, view azimuth and view elevation for the first and last frames of the replay section. These
view parameters are varied between these values for the other frames in the replay section.
Hint: These values can be copied from OrcaFlex's View Parameters form using the clipboard.
Graphics Mode
Specifies either the Wire frame or Shaded graphics mode for the replay section.
3.8 DATA FORMS
Each object in the model has data items that define its properties. The data are examined and edited in the object's
Data Form, which can be accessed by various methods:
� use the Model Browser
� DOUBLE CLICK the object in a 3D view
� RIGHT CLICK the object in a 3D view and use the pop-up menu.
