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.
