Questions tagged [lerp]

Lerp is a function which Interpolates between two values in a specific time `t` to create smooth animations.

Linearly interpolates between two vectors.

Interpolates between a and b by t. t is clamped between 0 and 1. It is used to create smooth changes of all type of ui controls. Changing the Audio, a Color or transform values of an game object in unity3d can be done with Lerp easily.

How to generalize linear interpolation between two numbers into higher dimension tensors?

Linear interpolation between two values is rather simple: def lerp(v, d): return v[0] * (1 - d) + v[1] * d print lerp(np.array([3, 5]), 0.75) > 4.5 Let generalize it to arbitrary tensors of shape (2, 2, …), i.e.: def lerp(v, d): assert…
