Detailed Description

This class implements the tetrahedral complex tensegrity spine based on the work of Tom Flemons This is similar to the version in examples, but uses muscles with contact dynamics

Member Function Documentation

void tgModel::addChild ( tgModel pChild)
inherited

Add a sub-model to this model. The model takes ownership of the child sub-model and is responsible for deallocating it.

Parameters
[in,out]pChilda pointer to a sub-model
Exceptions
std::invalid_argumentis pChild is NULL, this object, or already a descendant
Todo:
Make sure that every child appears no more than once in the tree.

Here is the caller graph for this function:

void tgSubject< BaseSpineModelLearning >::attach ( tgObserver< BaseSpineModelLearning > *  pObserver)
inherited

Attach an observer to the subject of the observer.

Parameters
[in,out]pObservera pointer to an observer for the subject; do nothing if the pointer is NULL
template<typename T >
std::vector<T*> tgModel::find ( const tgTagSearch tagSearch)
inlineinherited

Get a vector of descendants sorted by type and a tagsearch. Useful for pulling out muscle groups, or similar.

Parameters
[in]tagSearch,atagSearch that contains the desired tags
Returns
a std::vector of pointers to members that match the tag search and typename T

Definition at line 128 of file tgModel.h.

Here is the call graph for this function:

template<typename T >
std::vector<T*> tgModel::find ( const std::string &  tagSearch)
inlineinherited

Get a vector of descendants sorted by type and a tagsearch. Useful for pulling out muscle groups, or similar.

Parameters
[in]tagSearch,astd::string& that contains the desired tags
Returns
a std::vector of pointers to members that match the tag search and typename T

Definition at line 141 of file tgModel.h.

Here is the call graph for this function:

std::vector< tgModel * > tgModel::getDescendants ( ) const
inherited

Return a std::vector of const pointers to all sub-models.

Todo:
examine whether this should be public, and perhaps create a read only version
Returns
a std::vector of const pointers all sub-models.
Todo:
Unnecessary copying can be avoided by pasing the result collection in the recursive step.

Definition at line 170 of file tgModel.cpp.

Here is the call graph for this function:

std::vector< tgSenseable * > tgModel::getSenseableDescendants ( ) const
virtualinherited

From tgSenseable: need to return all the children of this class. Since tgModels are tgSenseables, just return getDescendants().

Returns
a vector of tgModels, with pointers changed into pointers for tgSenseables.

For tgSenseable: just return the results of getDescendants here. This should be OK, since a vector of tgModel* is also a vector of tgSenseable*.

Reimplemented from tgSenseable.

Definition at line 191 of file tgModel.cpp.

Here is the call graph for this function:

void tgSubject< BaseSpineModelLearning >::notifySetup ( )
inherited

Call tgObserver<T>::onSetup() on all observers in the order in which they were attached.

Here is the caller graph for this function:

void tgSubject< BaseSpineModelLearning >::notifyStep ( double  dt)
inherited

Call tgObserver<T>::onStep() on all observers in the order in which they were attached.

Parameters
[in]dtthe number of seconds since the previous call; do nothing if not positive

Here is the caller graph for this function:

void tgSubject< BaseSpineModelLearning >::notifyTeardown ( )
inherited

Call tgObserver<T>::onTeardown() on all observers in the order in which they were attached.

Here is the caller graph for this function:

void tgModel::onVisit ( const tgModelVisitor r) const
virtualinherited

Call tgModelVisitor::render() on self and all descendants.

Parameters
[in,out]ra reference to a tgModelVisitor

Reimplemented in tgCompressionSpringActuator, tgUnidirComprSprActuator, ConnectorTestModel, BuildTestModel, tgKinematicActuator, tgSphere, tgBox, tgRod, ContactCableDemo, tgBasicActuator, hillyMuscleNP, simpleMuscleNP, tgBoxMoreAnchors, tgBaseRigid, and tgGhostModel.

Definition at line 107 of file tgModel.cpp.

Here is the call graph for this function:

void FlemonsSpineModelGoal::setup ( tgWorld world)
virtual

Setup takes a tgWorld and passes it to any children for their own setup functions. All subclasses should call this at the appropriate time (usually end of setup) within their own setup function.

Parameters
[in]world- the tgWorld the models will exist in.
Todo:
: reference the things that do this for us
Todo:
: there seems to be an issue with Muscle2P connections if the front of a tetra is inside the next one.
Todo:
: the snake is a temporary variable – will its destructor be called? If not, where do we delete its children?

Reimplemented from BaseSpineModelGoal.

Definition at line 90 of file FlemonsSpineModelGoal.cpp.

void FlemonsSpineModelGoal::step ( double  dt)
virtual

Advance the simulation.

Parameters
[in]dtthe number of seconds since the previous call; std::invalid_argument is thrown if dt is not positive
Exceptions
std::invalid_argumentif dt is not positive
Note
This is not necessarily const for every child.

Reimplemented from BaseSpineModelGoal.

Definition at line 248 of file FlemonsSpineModelGoal.cpp.

Here is the call graph for this function:

void FlemonsSpineModelGoal::teardown ( )
virtual

Deletes the children (undoes setup)

Reimplemented from BaseSpineModelGoal.

Definition at line 241 of file FlemonsSpineModelGoal.cpp.

Here is the call graph for this function:

std::string tgModel::toString ( std::string  prefix = "") const
virtualinherited

Returns the tag names of this model and its children

Parameters
[in]prefixa string to append to
Returns
the original string with this model and its children's tags appended
