(

)

Default constructor.

WrapSphereObst::WrapSphereObst

(

const WrapSphereObst &

Member Function Documentation

Object * WrapSphereObst::copy

(

)

const [virtual]

Copy this WrapSphereObst and return a pointer to the copy.

The copy constructor for this class is used.

Returns:

Pointer to a copy of this WrapSphereObst.

Implements OpenSim::WrapObject.

void WrapSphereObst::copyData

(

const WrapSphereObst &

aWrapSphereObst

)

Copy data members from one WrapSphereObst to another.

Parameters:

aWrapSphereObst

WrapSphereObst to be copied.

Reimplemented from OpenSim::WrapObject.

string WrapSphereObst::getDimensionsString

(

)

const [virtual]

Get a string holding the dimensions definition that SIMM would use to describe this object.

This is a rather ugly convenience function for outputting SIMM joint files.

Returns:

A string containing the dimensions of the wrap object

Reimplemented from OpenSim::WrapObject.

double OpenSim::WrapSphereObst::getLength

(

)

const [inline]

double OpenSim::WrapSphereObst::getRadius

(

)

const [inline]

const char * WrapSphereObst::getWrapTypeName

(

)

const [virtual]

Get the name of the type of wrap object ("cylinderObst" in this case).

Returns:

A string representing the type of wrap object

Implements OpenSim::WrapObject.

WrapSphereObst & WrapSphereObst::operator=

(

const WrapSphereObst &

aWrapSphereObst

)

Assignment operator.

Returns:

Reference to this object.

Reimplemented from OpenSim::WrapObject.

virtual void OpenSim::WrapSphereObst::scale

(

const SimTK::Vec3 &

aScaleFactors

)

[inline, virtual]

Scale the wrap object by aScaleFactors.

This base class method scales only the _translation property, which is a local member. The derived classes are expected to scale the object itself, because they contain the object's dimensions.

Parameters:

aScaleFactors

The XYZ scale factors.

Reimplemented from OpenSim::WrapObject.

void OpenSim::WrapSphereObst::setLength

(

double

aLength

)

[inline]

void OpenSim::WrapSphereObst::setRadius

(

double

aRadius

)

[inline]

void WrapSphereObst::setup	(	Model &	aModel,
		OpenSim::Body &	aBody
	)			[virtual]

Perform some set up functions that happen after the object has been deserialized or copied.

Parameters:

aModel

point to OpenSim Model.

Reimplemented from OpenSim::WrapObject.

void WrapSphereObst::setupProperties

(

void

)

[protected]

Connect properties to local pointers.

Reimplemented from OpenSim::WrapObject.

int WrapSphereObst::wrapLine	(	const SimTK::State &	s,
		SimTK::Vec3 &	aPoint1,
		SimTK::Vec3 &	aPoint2,
		const PathWrap &	aMuscleWrap,
		WrapResult &	aWrapResult,
		bool &	aFlag
	)			const [virtual]

Calculate the wrapping of one line segment over the sphere located at the obstacle origin.

Parameters:

	aPointP	One end of the line segment, already expressed in obstacle frame
	aPointS	The other end of the line segment, already expressed in obstacle frame
	aMuscleWrap	An object holding the parameters for this line/cylinder pairing
	aWrapResult	The result of the wrapping (tangent points, etc.)
	aFlag	A flag for indicating errors, etc.

Returns:

The status, as a WrapAction enum

Implements OpenSim::WrapObject.
