LerpVectors

void fil::LerpVectors
(
	const fil::Vector2D& inVector0,
	const fil::Vector2D& inVector1,
	const float inLambda,
	fil::Vector2D& outVector
)

LerpVectors performed on red inVector0 = (150, 150) and blue inVector1 = (-50, 50) with inLambda = 0,25. Green is the resulting outVector.

LerpVectors performed on red inVector0 = (50, 50) and blue inVector1 = (-25, 25) with inLambda = -1,0. Green is the resulting outVector.

Please note that:

• interpolation begins at inVector0,
• for positive inLambda values interpolation is performed in the direction of inVector1 while for negative - in the direction of a vector which, when visualized with the same base point, ends in the point acquired by mirroring the head of inVector0 by a line perpendicular to the vector (inVector0 - inVector1).

Hence when inLambda = 0,0, outVector is equal to inVector0, while for inLambda = 1,0 it's the same as inVector1 and for inLambda = -1,0 - as the previously described vector. Other inLambda values interpolate between the input vectors and beyond.
