● NEW: Creates a new keyframe with the current 3D view.
● EDIT: Provides access to the properties of the selected keyframe.
● UPDATE POSITION: Changes the camera position associated with the
selected keyframe to the current 3D view.
● DELETE: Deletes the selected keyframe(s).
● Preview: Clicking the START button calls the display of the camera movement
through the selected keyframes in the list. This simulates the
movement during recording of an *.AVI file in the selected speed. The
preview can be canceled with ESC.
● Columns:
- The Movement time between two keyframes is computed automatically
as the difference between start and dwell times of the current
keyframe and the start time of the following one. It is not possible to
insert a keyframe into the list that overlaps with an existing one.
The type of movement is shown right behind the movement time, it is
indicated by the starting letter(s) of the corresponding type.
- The Focal Length (Field of View) column contains current settings by
keyframe, cf. section 4.3.1.3
● Absolute Start Times: If this option has been checked, the Start times are
regarded as absolute simulation times.
If this option has not been checked, start time data counts from the
moment in time when the AVI RECORDING command is activated in the
PRESENTATION menu. Thus the process does no longer automatically start
from the moment when the AVI RECORDING command is clicked. Via
menu PRESENTATION – 3D-VIDEO – KEYFRAMES, the start can be delayed
with a start time entry > 0 s for the first keyframe.
Thus you can enter Start time = 0 for the first keyframe to start the run
immediately by clicking the AVI RECORDING command as usually.
