Generate fractal octaves of noise.
Summing increasingly scaled amounts of noise with itself creates fractal clouds of noise.

Returns: | Scaled fractal noise |
Generate fractal octaves of noise.
Parameters: | |
---|---|
Returns: | Scaled fractal noise |
Generate an offset noise difference field.
Parameters: | |
---|---|
Returns: | Difference of noises |
Generate simplex noise at the given coordinates.
This particular implementation has very high chaotic features at normal resolution; zooming in by a factor of 16x to 256x is going to yield more pleasing results for most applications.
The gradient field must be seeded prior to calling this function; call reseed() first.
Parameters: | |
---|---|
Returns: | simplex noise |
Raises Exception: | |
the gradient field is not seeded |
Generate simplex noise at the given coordinates.
This is a 3-dimensional flavor of simplex2(); all of the same caveats apply.
The gradient field must be seeded prior to calling this function; call reseed() first.
Parameters: | |
---|---|
Returns: | simplex noise |
Raises Exception: | |
the gradient field is not seeded or you broke the function somehow |
