OpenDEStatePropagator (const SpaceInformationPtr &si) | |
Construct a representation of OpenDE state propagator. If si->getStateSpace() does not cast to an OpenDEStateSpace, an exception is thrown. | |
const OpenDEEnvironmentPtr & | getEnvironment () const |
Get the OpenDE environment this state propagator operates on. | |
virtual bool | canPropagateBackward () const |
Some systems can only propagate forward in time (i.e., the duration argument for the propagate() function is always positive). If this is the case, this function should return false. Planners that need backward propagation (negative durations) will call this function to check. If backward propagation is possible, this function should return true (this is the default). | |
virtual void | propagate (const base::State *state, const Control *control, const double duration, base::State *result) const |
Propagate from a state, given a control, for some specified amount of time (the amount of time can also be negative, if canPropagateBackward() returns true) | |
Protected Attributes | |
OpenDEEnvironmentPtr | env_ |
The OpenDE environment this state propagator operates on. |
Detailed Description
State propagation with OpenDE. Only forward propagation is possible.
At every propagation step, controls are applied using OpenDEEnvironment::applyControl(), contacts are computed by calling dSpaceCollide() on the spaces in OpenDEEnvironment::collisionSpaces_ and then dWorldQuickStep() is called. If the state argument of propagate() does not have its OpenDEStateSpace::StateType::collision field set, it is set based on the information returned by contact computation. Certain collisions (contacts) are allowed, as indicated by OpenDEEnvironment::isValidCollision().

void ompl::control::OpenDEStatePropagator::propagate | ( | const base::State * | state, |
const Control * | control, | ||
const double | duration, | ||
base::State * | result | ||
) | const [virtual] |
Propagate from a state, given a control, for some specified amount of time (the amount of time can also be negative, if canPropagateBackward() returns true)
- Parameters:
-
state the state to start propagating from control the control to apply duration the duration for which the control is applied result the state the system is brought to
- Note:
- This function is not used for integration internally. If integrating a system of differential equations is needed, this should be implemented inside the propagate() function.
- The pointer to the starting state and the result state may be the same.
Implements ompl::control::StatePropagator.
