Function Documentation

◆ GetEngine()

std::mt19937 * open3d::utility::random::GetEngine ( )

Get global singleton random engine. You must also lock the global mutex before calling the engine.


// Put the lock and the call to the engine in the same scope.
std::lock_guard<std::mutex> lock(*utility::random::GetMutex());
std::shuffle(vals.begin(), vals.end(), *utility::random::GetEngine());
std::mt19937 * GetEngine()
Definition: Random.cpp:55
std::mutex * GetMutex()
Definition: Random.cpp:57

◆ GetMutex()

std::mutex * open3d::utility::random::GetMutex ( )

Get global singleton mutex to protect the engine call. Also see random::GetEngine().

◆ RandUint32()

uint32_t open3d::utility::random::RandUint32 ( )

Generate a random uint32. This function is globally seeded by utility::random::Seed(). This function is automatically protected by the global random mutex.

◆ Seed()

void open3d::utility::random::Seed ( const int  seed)

Set Open3D global random seed.
