class flamegpu::HostRandom
Utility for accessing random generation within host functions This is prefered over using std random, as it uses a common seed with the device random This should only be instantiated by HostAPI
Public Functions
-
template<typename T>
inline T uniform() const Returns a float uniformly distributed between 0.0 and 1.0.
Note
It may return from 0.0 to 1.0, where 0.0 is included and 1.0 is excluded.
Note
Available as float or double
- Template Parameters
T – return type (must be floating point)
-
template<typename T>
inline T normal() const Returns a normally distributed float with mean 0.0 and standard deviation 1.0.
Note
This result can be scaled and shifted to produce normally distributed values with any mean/stddev.
Note
Available as float or double
- Template Parameters
T – return type (must be floating point)
-
template<typename T>
inline T logNormal(const T &mean, const T &stddev) const Returns a log-normally distributed float based on a normal distribution with the given mean and standard deviation.
Note
Available as float or double
- Template Parameters
T – return type (must be floating point)
-
template<typename T>
inline T uniform(const T &min, const T &max) const Returns an integer uniformly distributed in the inclusive range [lowerBound, max]
Note
Available as signed and unsigned: char, short, int, long long
- Template Parameters
T – return type (must be integer)
-
void setSeed(const uint64_t &seed)
Change the seed used for random generation
- Parameters
seed – New random seed
-
uint64_t getSeed() const
Returns the last value used to seed random generation
-
template<>
inline char uniform(const char &min, const char &max) const Special cases, std::random doesn’t support char, emulate behaviour
-
template<>
inline unsigned char uniform(const unsigned char &min, const unsigned char &max) const
-
template<>
inline signed char uniform(const signed char &min, const signed char &max) const
-
template<typename T>
