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.

Example:

#include "open3d/utility/Random.h"
 
{
    // 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());
}

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.
