C# Class LibNoise.Primitive.BevinsGradient

0-args constructor

Create a new BevinsGradientNoise with given values

Generates an output value given the coordinates of the specified input value.

Generates a gradient-coherent-noise value from the coordinates of a three-dimensional input value. The return value ranges from -1.0 to +1.0. For an explanation of the difference between gradient noise and value noise, see the comments for the GradientNoise3D() function.

Generates a gradient-noise value from the coordinates of a three-dimensional input value and the integer coordinates of a nearby three-dimensional value. The difference between fx and ix must be less than or equal to one. The difference between fy and iy must be less than or equal to one. The difference between fz and iz must be less than or equal to one. A gradient-noise function generates better-quality noise than a value-noise function. Most noise modules use gradient noise for this reason, although it takes much longer to calculate. The return value ranges from -1.0 to +1.0. This function generates a gradient-noise value by performing the following steps: - It first calculates a random normalized vector based on the nearby integer value passed to this function. - It then calculates a new value by adding this vector to the nearby integer value passed to this function. - It then calculates the dot product of the above-generated value and the floating-point input value passed to this function. A noise function differs from a random-number generator because it always returns the same output value if the same input value is passed to it.
