Member Function Documentation

Cosine() [1/2]

static float pluginbase.Helpers.Computative.Interpolate.Cosine ( float  a, float  b, float  u  )

static

Use cosine interpolation over a u time

Parameters

a	The alpha component.
b	The blue component.
u	U.

        {
            u = (1f - (float)Math.Cos(u * Math.PI)) * 0.5f;
            return a * (1f - u) + b * u;
        }

Cosine() [2/2]

static double pluginbase.Helpers.Computative.Interpolate.Cosine ( double  a, double  b, double  u  )

static

Use cosine interpolation over a u time

Parameters

a	The alpha component.
b	The blue component.
u	U.

        {
            u = (1f - (float)Math.Cos(u * Math.PI)) * 0.5f;
            return a * (1f - u) + b * u;
        }

Linear() [1/2]

static float pluginbase.Helpers.Computative.Interpolate.Linear ( float  a, float  b, float  u  )

static

Linearly interpolate two numbers by a 0-1 range

Parameters

a	The alpha component.
b	The blue component.
u	U.

        {
            return a * (1f - u) + b * u;
        }

Linear() [2/2]

static double pluginbase.Helpers.Computative.Interpolate.Linear ( double  a, double  b, double  u  )

static

Linearly interpolate two numbers by a 0-1 range

Parameters

a	The alpha component.
b	The blue component.
u	U.

        {
            return a * (1f - u) + b * u;
        }

SmoothStep() [1/2]

static float pluginbase.Helpers.Computative.Interpolate.SmoothStep ( float  a, float  b, float  u  )

static

Smooth interpolation, similar to cosine, but much faster

Returns

The step.

Parameters

a	The alpha component.
b	The blue component.
u	U.

        {
            u = u * u * (3f - 2f * u);
            return a * (1f - u) + b * u;
        }

SmoothStep() [2/2]

static double pluginbase.Helpers.Computative.Interpolate.SmoothStep ( double  a, double  b, double  u  )

static

Smooth interpolation, similar to cosine, but much faster

Returns

The step.

Parameters

a	The alpha component.
b	The blue component.
u	U.

        {
            u = u * u * (3f - 2f * u);
            return a * (1f - u) + b * u;
        }
