Member Function Documentation
◆ sampleGaussian()
|
overridevirtual |
Sample a state using a Gaussian distribution with given mean and standard deviation (stdDev).
As with sampleUniform, the implementation of sampleGaussian is specific to the derived class and few assumptions can be made about the distance between state and mean.
Reimplemented from ompl::base::DeterministicStateSampler.
Definition at line 211 of file DeterministicStateSampler.cpp.
◆ sampleUniformNear()
|
overridevirtual |
Sample a state near another, within a neighborhood controlled by a distance parameter.
Typically, StateSampler-derived classes will return in state a state that is uniformly distributed within a ball with radius distance defined by the distance function from the corresponding state space. However, this is not guaranteed. For example, the default state sampler for the RealVectorStateSpace returns samples uniformly distributed using L_inf distance, while the default distance function is L_2 distance.
