This class provides an implementation of Perlin noise for 2 variables.
This code is loosely based on the reference implementation at http://mrl.nyu.edu/~perlin/noise/ .
| PerlinNoise2 | ( | ) |
Randomizes the tables to make a unique noise function.
Uses a default scale (noise frequency), table size, and seed.
| PerlinNoise2 | ( | PerlinNoise2 const | copy | ) |
Makes an exact copy of the existing PerlinNoise object, including its random seed.
| PerlinNoise2 | ( | double | sx, |
| double | sy, | ||
| int | table_size, | ||
| unsigned long int | seed | ||
| ) |
Randomizes the tables to make a unique noise function.
If seed is nonzero, it is used to define the tables; if it is zero a random seed is generated.
| PerlinNoise2 | ( | double | sx, |
| double | sy, | ||
| int | table_size | ||
| ) |
Randomizes the tables to make a unique noise function.
If seed is nonzero, it is used to define the tables; if it is zero a random seed is generated.
| PerlinNoise2 | ( | double | sx, |
| double | sy | ||
| ) |
Randomizes the tables to make a unique noise function.
If seed is nonzero, it is used to define the tables; if it is zero a random seed is generated.
| double noise | ( | VBase2D const | value | ) |
Returns the noise function of the three inputs.
| double noise | ( | double | x, |
| double | y | ||
| ) |
Returns the noise function of the three inputs.
| float noise | ( | VBase2 const | value | ) |
Returns the noise function of the three inputs.
| double operator() | ( | double | x, |
| double | y | ||
| ) |
Returns the noise function of the two inputs.
| double operator() | ( | VBase2D const | value | ) |
