Detailed Description

Complement to full transformation constraint of ConvexShapeContact

The value returned by this class is:

| Contact type | Inside | Outside | | -----------— | -----— | ----— | | ConvexShapeContact::POINT_ON_PLANE (Unsupported) | $(y,z,rx)$ | $(0,0,rx)$ | | ConvexShapeContact::LINE_ON_PLANE (Unsupported) | | | | ConvexShapeContact::PLANE_ON_PLANE | $(y+2jM,z+2iM,rx)$ | $(2jM,2iM,rx)$ |

where

is an upper bound on the radius of all floor polygons,
and are the indices of object and floor contact surfaces that minimize
$\begin{equation} d(o_i,f_j) \end{equation}$

		std::size_t &	ifloor,
		std::size_t &	iobject,
		LiegroupElementRef	relativePoseRhs
	)		const

Compute parameters and right hand side of relative pose

Parameters

rhs	right hand side of this constraint,

Return values

ifloor,iobject	indices of floor and object contact surface,
relativePoseRhs	right hand side (implicit representation) of the relative pose constraint corresponding to contact of surfaces ifloor with iobject.

Create a pair of constraints

Parameters

name	name of the sibling ConvexShapeContact constraint, "/complement" is added to the name of this constraint
robot	robot that holds the contact surface
floorSurfaces,objectSurfaces	set of plane polygonal contact surfaces.

◆ dependsOnRelPoseBetween()

std::pair<JointConstPtr_t, JointConstPtr_t> hpp::constraints::ConvexShapeContactComplement::dependsOnRelPoseBetween ( DeviceConstPtr_t ) const

inlinevirtual

Return pair of joints the relative pose between which modifies the function value if any

Currently only supports the case when all the joints for floors are the same and all the joints for objects involved are the same

Returns: pair of joints whose relative pose determines the value of the contact function, arranged in order of increasing joint index, or a pair of empty shared pointers.

Reimplemented from hpp::constraints::DifferentiableFunction.

◆ isEqual()

bool hpp::constraints::ConvexShapeContactComplement::isEqual ( const DifferentiableFunction & other ) const
