[−][src]Struct nannou::noise::Cache
Noise function that caches the last output value generated by the source function.
If the input coordinates passed to Cache::get
are equal to the previous
call, the function returns the cached result of the previous call to
Source::get
. Otherwise, Source::get
is called with the new coordinates,
overwriting the cache with the result, and returning the result to the
caller.
Caching a noise function is useful if it is used as a source function for multiple noise functions. If a source function is not cached, the source function will redundantly calculate the same output value once for each noise function in which it is included.
Fields
source: &'a Source
Outputs the value to be cached.
