The value at the specified position.
When you create a noise map from a
GKNoise object, GameplayKit performs the noise generation and processing computations necessary to fill a discrete grid with noise samples. (You specify the size of the grid and its number of samples in the
init initializer.) You can use this method to get noise values for arbitrary positions in the noise field, regardless of whether those positions are aligned with the discrete grid. When you query a position not aligned with the grid, this method automatically samples nearby grid positions and interpolates the results.
To query only positions within the discrete sample grid, use the
value method instead.
