## Public Member Functions

Body ()
BodyPtr cloneAt (const Eigen::Affine3d &pose) const
Get a clone of this body, but one that is located at the pose pose.
virtual BodyPtr cloneAt (const Eigen::Affine3d &pose, double padding, double scaling) const =0
Get a clone of this body, but one that is located at the pose pose and has possibly different passing and scaling: padding and scaling. This function is useful to implement thread safety, when bodies need to be moved around.
virtual void computeBoundingCylinder (BoundingCylinder &cylinder) const =0
Compute the bounding cylinder for the body, in its current pose. Scaling and padding are accounted for.
virtual void computeBoundingSphere (BoundingSphere &sphere) const =0
Compute the bounding radius for the body, in its current pose. Scaling and padding are accounted for.
virtual double computeVolume () const =0
Compute the volume of the body. This method includes changes induced by scaling and padding.
bool containsPoint (double x, double y, double z, bool verbose=false) const
Check if a point is inside the body.
virtual bool containsPoint (const Eigen::Vector3d &p, bool verbose=false) const =0
Check if a point is inside the body.
virtual std::vector< double > getDimensions () const =0
Get the dimensions associated to this body (as read from corresponding shape)
double getPadding () const
Retrieve the current padding.
const Eigen::Affine3d & getPose () const
Retrieve the pose of the body.
double getScale () const
Retrieve the current scale.
shapes::ShapeType getType () const
Get the type of shape this body represents.
virtual bool intersectsRay (const Eigen::Vector3d &origin, const Eigen::Vector3d &dir, EigenSTL::vector_Vector3d *intersections=NULL, unsigned int count=0) const =0
Check if a ray intersects the body, and find the set of intersections, in order, along the ray. A maximum number of intersections can be specified as well. If that number is 0, all intersections are returned.
virtual bool samplePointInside (random_numbers::RandomNumberGenerator &rng, unsigned int max_attempts, Eigen::Vector3d &result)
Sample a point that is included in the body using a given random number generator. Sometimes multiple attempts need to be generated; the function terminates with failure (returns false) after max_attempts attempts. If the call is successful (returns true) the point is written to result.
void setDimensions (const shapes::Shape *shape)
Set the dimensions of the body (from corresponding shape)
If constant padding should be added to the body, this method sets the padding. Default is 0.0.
void setPose (const Eigen::Affine3d &pose)
Set the pose of the body. Default is identity.
void setScale (double scale)
If the dimension of the body should be scaled, this method sets the scale. Default is 1.0.
virtual ~Body ()

## Protected Member Functions

virtual void updateInternalData ()=0
This function is called every time a change to the body is made, so that intermediate values stored for efficiency reasons are kept up to date.
virtual void useDimensions (const shapes::Shape *shape)=0
Depending on the shape, this function copies the relevant data to the body.

## Protected Attributes

The scale that was set for this body.
Eigen::Affine3d pose_
The location of the body (position and orientation)
double scale_
The scale that was set for this body.
shapes::ShapeType type_
The type of shape this body was constructed from.
