Third Party Fuses/Interpolation2D Description
From VFXPedia
Interpolation2D_v1_0
A modifier Fuse that calculates a position between two or four points.
- 2 Points: A simple slider to define a position between two points. Extrapolation is also possible if the slider is < 0 or > 1. If you average a tracker's path with 0.5/0.5 you can achieve partial stabilization or partial matchmoving (useful for faking 2.5D parallax).
- 4 Points: Round-trip between 4 points.
- Weighted 4: Each point is assigned a corresponding weight. The result is calculated from the 4 coordinates, multiplied by their weight.
Known issue: When the modifier is added, the result is set to a hard-coded default value, not to the value that was there before. Currently, the Fuse API doesn't allow changing this. If, however, the modifier is inserted into an already animated or published input, the value will be kept.
- Main Inputs
- Controls
- Type
- Select mode of operation.
- Point1 to Point4
- Connect your 2D paths here.
- Interpolated Position
- 0 equals Point1, 1 equals Point2 and so on. In 2 Points mode, values outside the 0..1 range extrapolate the position. In 4 Points mode, values larger than 3 interpolate from Point4 back to Point1, where the loop starts over.
- Weight1 to Weight4
- In weighted mode, these sliders define how much each point influences the result.
- Normalize Weights
- If checked, all weights will be scaled internally to make sure their sum equals 1.0 at all times (except if all weights are zero).
