ompl::base::SO3StateSpace Class Reference

A state space representing SO(3). The internal representation is done with quaternions. The distance between states is the angle between quaternions and interpolation is done with slerp. More...

Member Function Documentation

virtual State* ompl::base::SO3StateSpace::allocState ( void   )  const [virtual]

Allocate a state that can store a point in the described space.

Implements ompl::base::StateSpace.

virtual StateSamplerPtr ompl::base::SO3StateSpace::allocStateSampler ( void   )  const [virtual]

Allocate an instance of a uniform state sampler for this space.

Implements ompl::base::StateSpace.

virtual void ompl::base::SO3StateSpace::copyState ( State destination,
const State source 
) const [virtual]

Copy a state to another. The memory of source and destination should NOT overlap.

Implements ompl::base::StateSpace.

virtual double ompl::base::SO3StateSpace::distance ( const State state1,
const State state2 
) const [virtual]

Computes distance to between two states. This value will always be between 0 and getMaximumExtent().

Implements ompl::base::StateSpace.

virtual void ompl::base::SO3StateSpace::enforceBounds ( State state  )  const [virtual]

Bring the state within the bounds of the state space.

Implements ompl::base::StateSpace.

virtual bool ompl::base::SO3StateSpace::equalStates ( const State state1,
const State state2 
) const [virtual]

Checks whether two states are equal.

Implements ompl::base::StateSpace.

virtual void ompl::base::SO3StateSpace::freeState ( State state  )  const [virtual]

Free the memory of the allocated state.

Implements ompl::base::StateSpace.

virtual unsigned int ompl::base::SO3StateSpace::getDimension ( void   )  const [virtual]

Get the dimension of the space.

Implements ompl::base::StateSpace.

virtual double ompl::base::SO3StateSpace::getMaximumExtent ( void   )  const [virtual]

Get the maximum value a call to distance() can return.

Implements ompl::base::StateSpace.

virtual double* ompl::base::SO3StateSpace::getValueAddressAtIndex ( State state,
const unsigned int  index 
) const [virtual]

Many states contain a number of double values. This function provides a means to get the memory address of a double value from state state located at position index. The first double value is returned for index = 0. If index is too large (does not point to any double values in the state), the return value is NULL.

Note:
This function does not map a state to an array of doubles. There may be components of a state that do not correspond to double values and they are 'invisible' to this function. Furthermore, this function is slow and is not intended for use in the implementation of planners.

Reimplemented from ompl::base::StateSpace.

virtual void ompl::base::SO3StateSpace::interpolate ( const State from,
const State to,
const double  t,
State state 
) const [virtual]
