Computes a weighted average of (linearly interpolates between) two inputs, based on a third input. For each component of the result, the weighted average of the corresponding components of the first two inputs is computed. The weight is provided by the third input, a scalar, and is uniformly applied to all components. You can use this to interpolate between points, colors, attributes, and other values.
