Extract path

Description

I tend to hand move my cameras, in keymode, then I want to lock them down or smooth their movements with a spline, can a spline be extracted from hand keyed camera movements? If so this would be very useful to people like me.

Note: use animated camera

fn extractTrajectory cam step: startF: endF: =
(
local slinePaths = SplineShape name:(uniqueName "TrajectoryPath")
addNewSpline slinePaths
for t = startF to endF by step do
(
at time t
(
addKnot slinePaths 1 #smooth #line cam.pos
)
)
updateShape slinePaths
)
extractTrajectory $Camera001 step:5 startF:0 endF:100

Spline from keyed camera path
