DESCRIPTION

This engine linearly interpolates between two 4D 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

SoMFVec4f input0

SoMFVec4f input1

The engine linearly interpolates from input0 to input1.

METHODS

SoInterpolateVec4f()

Constructor.

FILE FORMAT/DEFAULTS

InterpolateVec4f {


alpha	0
input0	0 0 0 0
input1	0 0 0 0


}
