Detailed Description

A collision element descibes the collision properties associated with a link.

This can be different from the visual properties of a link. For example, simple collision models are often used to reduce computation time.

Constructor & Destructor Documentation

sdf::SDF_VERSION_NAMESPACE::Collision::Collision ( )

Default constructor.

Member Function Documentation

◆ AutoInertiaParams()

sdf::ElementPtr sdf::SDF_VERSION_NAMESPACE::Collision::AutoInertiaParams ( ) const

Get the ElementPtr to the <auto_inertia_params> element This element can be used as a parent element to hold user-defined params for the custom moment of inertia calculator.

Returns: ElementPtr object for the <auto_inertia_params> element.

◆ CalculateInertial() [1/2]

void sdf::SDF_VERSION_NAMESPACE::Collision::CalculateInertial	(	sdf::Errors &	_errors,
		gz::math::Inertiald &	_inertial,
		const ParserConfig &	_config
	)

Calculate and return the MassMatrix for the collision.

Parameters

[out]	_errors	A vector of Errors objects. Each errors contains an Error code and a message. An empty errors vector indicates no errors
[out]	_inertial	An inertial object which will be set with the calculated inertial values
[in]	_config	Custom parser configuration

◆ CalculateInertial() [2/2]

void sdf::SDF_VERSION_NAMESPACE::Collision::CalculateInertial	(	sdf::Errors &	_errors,
		gz::math::Inertiald &	_inertial,
		const ParserConfig &	_config,
		const std::optional< double > &	_density,
		sdf::ElementPtr	_autoInertiaParams
	)

Calculate and return the MassMatrix for the collision.

Parameters

[out]	_errors	A vector of Errors objects. Each errors contains an Error code and a message. An empty errors vector indicates no errors
[out]	_inertial	An inertial object which will be set with the calculated inertial values
[in]	_config	Custom parser configuration
[in]	_density	An optional density value to override the default collision density. This value is used instead of DefaultDensity()
[in]	_autoInertiaParams	An ElementPtr to the auto_inertia_params element to be used if the auto_inertia_params have not been set in this collision.

◆ Density()

double sdf::SDF_VERSION_NAMESPACE::Collision::Density ( ) const

Get the density of the collision.

Returns: Density of the collision.

◆ DensityDefault()

static double sdf::SDF_VERSION_NAMESPACE::Collision::DensityDefault ( )

static

Get the default density of a collision if its density is not specified.

Returns: Default density.

◆ Element()

sdf::ElementPtr sdf::SDF_VERSION_NAMESPACE::Collision::Element ( ) const

Get a pointer to the SDF element that was used during load.

Returns: SDF element pointer. The value will be nullptr if Load has not been called.

Get a pointer to the collisions's geometry.

Returns: The collision's geometry.

◆ Load() [1/2]

Errors sdf::SDF_VERSION_NAMESPACE::Collision::Load ( ElementPtr _sdf )

Load the collision based on a element pointer.

This is not the usual entry point. Typical usage of the SDF DOM is through the Root object.

Parameters

[in] _sdf The SDF Element pointer

Returns: Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

◆ Load() [2/2]

Errors sdf::SDF_VERSION_NAMESPACE::Collision::Load	(	sdf::ElementPtr	_sdf,

Load the collision based on a element pointer.

This is not the usual entry point. Typical usage of the SDF DOM is through the Root object.

Parameters

[in]	_sdf	The SDF Element pointer
[in]	_config	Parser configuration

Returns: Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

◆ Name()

std::string sdf::SDF_VERSION_NAMESPACE::Collision::Name ( ) const

Get the name of the collision.

The name of the collision must be unique within the scope of a Link.

Returns: Name of the collision.

◆ PoseRelativeTo()

Get the name of the coordinate frame relative to which this object's pose is expressed.

An empty value indicates that the frame is relative to the parent link.

Returns: The name of the pose relative-to frame.

◆ RawPose()
