The mathematical process the CNC controller performs to determine the time and distance each axis must move to insure a perfectly straight tool movement regardless of angle. G1 is the CNC programming word for linear interpolation under feed control. Example G1 X3Y-1F10.0 where F controls the feed rate.

A form of interpolation that uses the calculated mean of two sample points as the interpolated sample point See also: drop-sample conversion

A method that allows the prediction of an unknown value if any two particular values on the same scale are known and the rate of change is assumed constant.

To 'interpolate' means to calculate a new value in between two known values. Linear interpolation creates new values at equal distances along a line between two known values. When you animate objects with the Score or Stage and set the key positions of a sprite, Director computes the in-between (tweened) points to determine how the sprite moves from one keyframe to the next.

Linear interpolation is the process of using two known values at two points to determine a third unknown value at a third point.

A method of approximating data values by assuming that they lie along a straight line. Typically, the two end data points are known. For example, if A is the value at a, and B is the value at b, and atb, then the value C at t is (from the two-point formula): B - A divided by b - a, multiplied by t - D, added to A.

Linear interpolation (also known by the acronym lerping) is a method of curve fitting using linear polynomials. It is heavily employed in mathematics (particularly numerical analysis), and numerous applications including computer graphics. It is a simple form of interpolation.
