Detailed Description

Defines a 3-element floating point vector.

When using a vector to represent a surface normal, the vector should typically be normalized. Other uses of directional vectors may wish to leave the magnitude of the vector intact. When used as a point, the elements of the vector represent a position in 3D space.

	)

Updates this vector towards the given target using a smoothing function.

The given response time determines the amount of smoothing (lag). A longer response time yields a smoother result and more lag. To force this vector to follow the target closely, provide a response time that is very small relative to the given elapsed time.

Parameters

target	target value.
elapsedTime	elapsed time between calls.
responseTime	response time (in the same units as elapsedTime).

local smooth	(	local	target,
		local	elapsedTime,
		local	responseTime
	)

Updates this vector towards the given target using a smoothing function.

The given response time determines the amount of smoothing (lag). A longer response time yields a smoother result and more lag. To force this vector to follow the target closely, provide a response time that is very small relative to the given elapsed time.

Parameters

target	target value.
elapsedTime	elapsed time between calls.
responseTime	response time (in the same units as elapsedTime).
