Constructor & Destructor Documentation

◆ DynamicLines()

DynamicLines ( RenderOpType _opType = RENDERING_LINE_STRIP )

explicit

Constructor.

Parameters

[in] _opType The type of Line

◆ ~DynamicLines()

virtual ~DynamicLines ( )

virtual

Destructor.

Member Function Documentation

◆ AddPoint() [1/2]

void AddPoint	(	const ignition::math::Vector3d &	_pt,
		const ignition::math::Color &	_color = `ignition::math::Color::White`
	)

Add a point to the point list.

Parameters

[in]	_pt	ignition::math::Vector3d point
[in]	_color	ignition::math::Color Point color

◆ AddPoint() [2/2]

void AddPoint	(	const double	_x,
		const double	_y,
		const double	_z,
		const ignition::math::Color &	_color = `ignition::math::Color::White`
	)

Add a point to the point list.

Parameters

[in]	_x	X position
[in]	_y	Y position
[in]	_z	Z position
[in]	_color	ignition::math::Color Point color

◆ Clear()

void Clear ( )

Remove all points from the point list.

◆ getBoundingRadius()

virtual Ogre::Real getBoundingRadius ( ) const

virtualinherited

Implementation of Ogre::SimpleRenderable.

Returns: The bounding radius

◆ GetMovableType() [1/2]

static std::string GetMovableType ( )

static

Get type of movable.

Returns: This returns "gazebo::dynamiclines"

◆ getMovableType()

virtual const Ogre::String& getMovableType ( ) const

virtual

Overridden function from Ogre's base class.

Returns: Returns "gazebo::ogredynamicslines"

◆ GetMovableType() [2/2]

std::string GetMovableType ( ) const

inherited

Get type of movable.

Returns: This returns "gazebo::DynamicRenderable"

◆ GetOperationType()

RenderOpType GetOperationType ( ) const

inherited

Get the render operation type.

Returns: The render operation type.

◆ GetPointCount()

unsigned int GetPointCount ( ) const

Return the total number of points in the point list.

Returns: Number of points

◆ getSquaredViewDepth()

virtual Ogre::Real getSquaredViewDepth ( const Ogre::Camera * _cam ) const

virtualinherited

Implementation of Ogre::SimpleRenderable.

Parameters

[in] _cam Pointer to the Ogre camera that views the renderable.

Returns: The squared depth in the Camera's view

◆ Init()

void Init	(	RenderOpType	_opType,
		bool	_useIndices = `false`
	)

inherited

Initializes the dynamic renderable.

Remarks: This function should only be called once. It initializes the render operation, and calls the abstract function CreateVertexDeclaration().

Parameters

[in]	_opType	The type of render operation to perform.
[in]	_useIndices	Specifies whether to use indices to determine the vertices to use as input.

◆ Point()

ignition::math::Vector3d Point ( const unsigned int _index ) const

Return the location of an existing point in the point list.

Parameters

[in] _index Number of the point to return

Returns: ignition::math::Vector3d value of the point. A vector of [ignition::math::INF_D, ignition::math::INF_D, ignition::math::INF_D] is returned when then the _index is out of bounds. ignition::math::INF_D==std::numeric_limits<double>::infinity()

◆ PrepareHardwareBuffers()

void PrepareHardwareBuffers	(	size_t	_vertexCount,
		size_t	_indexCount
	)

protectedinherited

Prepares the hardware buffers for the requested vertex and index counts.

Remarks: This function must be called before locking the buffers in fillHardwareBuffers(). It guarantees that the hardware buffers are large enough to hold at least the requested number of vertices and indices (if using indices). The buffers are possibly reallocated to achieve this.

The vertex and index count in the render operation are set to: the values of vertexCount and indexCount respectively.

Parameters

[in]	_vertexCount	The number of vertices the buffer must hold.
[in]	_indexCount	The number of indices the buffer must hold. This parameter is ignored if not using indices.

◆ SetColor()

void SetColor	(	const unsigned int	_index,
		const ignition::math::Color &	_color
	)

Change the color of an existing point in the point list.

Parameters

[in]	_index	Index of the point to set
[in]	_color	ignition::math::Color Pixelcolor color to set the point to

◆ SetOperationType()

void SetOperationType ( RenderOpType _opType )

inherited

Set the render operation type.

Parameters

[in] _opType The type of render operation to perform.

◆ SetPoint()

void SetPoint	(	const unsigned int	_index,
		const ignition::math::Vector3d &	_value
	)

Change the location of an existing point in the point list.

Parameters

[in]	_index	Index of the point to set
[in]	_value	ignition::math::Vector3d value to set the point to

◆ Update()

void Update ( )

Call this to update the hardware buffer after making changes.

Member Data Documentation

◆ indexBufferCapacity

size_t indexBufferCapacity

protectedinherited

Maximum capacity of the currently allocated index buffer.

◆ vertexBufferCapacity

size_t vertexBufferCapacity

protectedinherited

Maximum capacity of the currently allocated vertex buffer.
