[interpolator's example] [run]PositionInterpolators interpolate linearly among a set of SFVEC3f values (keyValue parameter). The vectors are interpreted as absolute positions in object space.
{
eventIn SFFloat set_fraction # this input float value causes the interpolator function to evaluate
exposedField MFFloat key [ ] # key values in the set_fraction domain
exposedField MFVec3f keyValue [ ] # functions values (1:1 related to above field)
eventOut SFVec3f value_changed # current output value (associated to the current time)
}
Usage :
PositionInterpolator {
key [0, 0.0833, 0.167, 0.25, 0.333, 0.417, 0.5,
0.583, 0.667, 0.75, 0.833, 0.917, 1]
keyValue [-8 0 0, -7 -4 0, -4 -6 0,
0 -7 0, 2.75 -5 0, 4 -3 0,
5 0 0, 4.00 3 0, 2.75 5 0,
0 7 0, -4 6 0, -7 4 0, -8 0 0]
