WebBlender 2.71 (or any recent build) has Vector.slerp (spherical linear interpolation) which accepts values outside 0-1 So you can do: a = Vector ( (1, 0, 0)) b = Vector ( (0, 1, 0)) c = a.slerp (b, 0.5) # half way To over rotate 10% do: c = a.slerp (b, 1.1) Note, this feature is not included in a stable release yet (but 2.71 will include it). Share WebNov 11, 2024 · Linear interpolation is the process of estimating an unknown value of a function between two known values.. Given two known values (x 1, y 1) and (x 2, y 2), we can estimate the y-value for some point x by using the following formula:. y = y 1 + (x-x 1)(y 2-y 1)/(x 2-x 1).
