* Launch with alt+P (or put it in .script folder)
22
Allow to see in real time trajectory of selected object.
24
On first run, it ask you
25
- If you want that actually selected object have they trajectory always shown
26
- If you want to use Space Handler or a Scriptlink in Redraw mode
27
- Future and Past : it is the frame in past and future
28
of the beggining and the end of the path
29
- Width of line that represent the trajectory
31
Then the object's trajectory will be shown in all 3D areas.
32
When trajectory is red, you can modifiy it by moving object.
33
When trajectory is blue and you want to be able to modify it, inser a Key (I-Key)
35
Points appears on trajectory :
36
- Left Clic to modify position
37
- Right Clic to go to the frame it represents
40
In scriptlink mode, it create one script link so make sure that 'Enable Script Link' toogle is on
41
In SpaceHandler mode, you have to go in View>>SpaceHandlerScript menu to activate Trajectory
