| Description |
Calculates linear interpolation from one vector to another vector. (Just like regular lerp(), but for vectors.) Note that there is one static version of this method, and two non-static versions. The static version, lerp(v1, v2, amt) is given the two vectors to interpolate and returns a new PVector object. The static version is used by referencing the PVector class directly. (See the middle example above.) The non-static versions, lerp(v, amt) and lerp(x, y, z, amt), do not create a new PVector, but transform the values of the PVector on which they are called. These non-static versions perform the same operation, but the former takes another vector as input, while the latter takes three float values. (See the top and bottom examples above, respectively.) |
