◆ AddPlane()

void chrono::ChBoundary::AddPlane ( const ChFrame<> &  frame,
const ChVector2<> &  lengths 
)

Add a collision plane with finite extent and return the plane ID.

The plane normal is in the Z-direction of the given frame.

Parameters
frameplane reference frame, relative to associated body
lengthsX-Y extent

◆ AddVisualization() [1/2]

void chrono::ChBoundary::AddVisualization ( double  thickness)

Add visualization for all existing planes.

Parameters
thicknessvisualization thickness

◆ AddVisualization() [2/2]

void chrono::ChBoundary::AddVisualization ( size_t  id,
double  thickness 
)

Add visualization for the specified plane.

Parameters
idplane indes
thicknessvisualization thickness

◆ Update()

void chrono::ChBoundary::Update ( )

Update all collision planes.


This function should be called if the position of the associated body is modified.

◆ UpdatePlane() [1/2]

void chrono::ChBoundary::UpdatePlane ( size_t  id,
const ChFrame<> &  frame 
)

Override the position of the specified collision plane.

Parameters
idplane index
frameplane reference frame, relative to associated body

◆ UpdatePlane() [2/2]

void chrono::ChBoundary::UpdatePlane ( size_t  id,
const ChVector2<> &  lengths 
)

Override the X-Y extent of the specified collision plane.

Parameters
idplane index
lengthsX-Y extent
