Overview
This engine linearly interpolates between two 2D vectors, based on the alpha input value. The alpha value should be between 0.0 and 1.0.
The input fields can have multiple vectors, allowing the engine to interpolate several objects in parallel. One of the inputs may have more values than the other. In that case, the last value of the shorter input will be repeated as necessary.
Inputs
SoMFVec2f input0
SoMFVec2f input1
The engine linearly interpolates from input0 to input1.
Methods
SoInterpolateVec2f()
Constructor.
File format/defaults
InterpolateVec2f {
alpha 0
input0 0 0
input1 0 0
}
