Method Details

interpolate

public float interpolate(float initial,
 float a,
 float b,
 float progress)

Specified by:

interpolate in interface FloatInterpolator

ensureCacheCapacity

private static float @NotNull [] ensureCacheCapacity(float @Nullable [] cache,
 int length)

arrayLerp

private static float @NotNull [] arrayLerp(float @Nullable [] cache,
 float @NotNull [] from,
 float @Nullable [] to,
 float progress)

saxpy

private static float @NotNull [] saxpy(float @Nullable [] cache,
 float @NotNull [] b,
 float @Nullable [] x,
 float a)

This method is used to calculate the result of the following operation: result_i = a * x_i + b_i

• If b_i is shorter than a_i, b_i is repeated.
• If b_i is longer than a_i, the extra values are ignored.
