Member Function Documentation

addObstacle()

void hpp::corbaserver::Obstacle::addObstacle	(	in string	objectName,
		in boolean	collision,

	)
raises	(	Error
	)

Add an obstacle to the set of obstacles.

Parameters

objectName	name of the object.
collision	whether collision with object should be computed
distance	whether distance to object should be computed

Exceptions

Error.

Note

The obstacle should have been built using one of methods

• hpp::Obstacle::createPolyhedron,
• hpp::Obstacle::createBox
• hpp::Obstacle::addPoint
• hpp::Obstacle::addTriangle.

Build the bounding volume hierarchy of the object if needed.

addPoint()

unsigned long hpp::corbaserver::Obstacle::addPoint	(	in string	polyName,
		in double	x,
		in double	y,
		in double	z
	)
raises	(	Error
	)

Add a point to a polyhedron.

Parameters

polyName	the name of the polyhedron.
x	coordinate of the point.
y	coordinate of the point.
z	coordinate of the point.

Returns

rank of point in polyhedron.

addTriangle()

unsigned long hpp::corbaserver::Obstacle::addTriangle	(	in string	polyName,
		in unsigned long	pt1,
		in unsigned long	pt2,
		in unsigned long	pt3
	)
raises	(	Error
	)

Add a point to a polyhedron.

Parameters

polyName	the name of the polyhedron.
pt1	rank of first point in polyhedron.
pt2	rank of second point in polyhedron.
pt3	rank of third point in polyhedron.

Returns

rank of triangle in polyhedron.

createBox()

void hpp::corbaserver::Obstacle::createBox	(	in string	inBoxName,
		in double	x,
		in double	y,
		in double	z
	)
raises	(	Error
	)

Create a box.

Parameters

inBoxName	name of the box
x,y,z	Size of the box

createCylinder()

void hpp::corbaserver::Obstacle::createCylinder	(	in string	name,
		in double	radius,
		in double	length
	)
raises	(	Error
	)

Create a cylinder

Parameters

name	name of the cylinder
radius	radius of the cylinder
length	length of the cylinder

createPolyhedron()

void hpp::corbaserver::Obstacle::createPolyhedron	(	in string	polyName	)
raises	(	Error
	)

create an empty polyhedron.

Parameters

polyName

name of the polyhedron.

Exceptions

Error.

createSphere()

void hpp::corbaserver::Obstacle::createSphere	(	in string	name,
		in double	radius
	)
raises	(	Error
	)

Create a sphere

Parameters

name	name of the sphere
radius	radius of the sphere

cutObstacle()

void hpp::corbaserver::Obstacle::cutObstacle	(	in string	objectName,
		in floatSeq	aabb
	)
raises	(	Error
	)

Cut the obstacle with the given AABB

Parameters

aabb	a vector of 6 floats. The 3 first represent one corner and the 3 last represent the opposite corner.

getObstacleNames()

Names_t hpp::corbaserver::Obstacle::getObstacleNames	(	in boolean	collision,
		in boolean	distance
	)
raises	(	Error
	)

Get list of obstacles

Parameters

collision	whether to return obstacle for collision,
distance	whether to return obstacles for distance computation

Returns

list of obstacles

getObstaclePosition()

void hpp::corbaserver::Obstacle::getObstaclePosition	(	in string	objectName,
		out Transform_	cfg
	)
raises	(	Error
	)

Get the position of an obstacle

Parameters

objectName

name of the polyhedron.

Return values

cfg	Position of the obstacle.

Exceptions

Error.

loadObstacleModel()

void hpp::corbaserver::Obstacle::loadObstacleModel	(	in string	filename,
		in string	prefix
	)
raises	(	Error
	)

Load obstacle from urdf file

Parameters

package	Name of the package containing the model.
filename	name of the urdf file, it may contain "package://"
prefix	prefix added to object names in case the same file is loaded several times

The kinematic structure of the urdf file is ignored. Only the geometric objects are loaded as obstacles.

loadObstacleModelFromString()

void hpp::corbaserver::Obstacle::loadObstacleModelFromString	(	in string	urdfString,
		in string	prefix
	)
raises	(	Error
	)

Load obstacle from urdf file

Parameters

package	Name of the package containing the model.
urdfString	XML string to parse
prefix	prefix added to object names in case the same file is loaded several times

The kinematic structure of the urdf file is ignored. Only the geometric objects are loaded as obstacles.

loadPolyhedron()

void hpp::corbaserver::Obstacle::loadPolyhedron	(	in string	obstacleName,
		in string	filename
	)
raises	(	Error
	)

Load a polyhedron as an obstacle from a file.

Parameters

obstacleName	name of the polyhedron.
filename	name of the file.

Exceptions

Error.
