Library - Interpolation

The Library is where code samples, building blocks of scripts will be shared.

linear1D: n1,n2,i // i = interpolation point (0-1)
{
    return(n1 * (1 - i) + n2 * i);     
}

cosine1D: n1,n2,i // i = interpolation point (0-1)
{
    i2 = (1 - cos(i * 3.1415926535)) * 0.5;
    return(n1 * (1 - i2) + n2 * i2);     
}

bicubic1D: n1,n2,n3,n4,i // i = interpolation point (0-1)
{
    i2 = i * i;
    n_01 = n4 - n3 - n1 + n2;
    n_02 = n1 - n2 - n_01;
    n_03 = n3 - n1;
    n_04 = n2;
    return(n_01 * i * i2 + n_02 * i2 + n_03 * i + n_04);
