Member Function Documentation

AddPoint() [1/2]

void AddPoint	(	const double	_x,
		const double	_y,
		const double	_z,
		const gz::math::Color &	_color = gz::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	gz::math::Color Point color

AddPoint() [2/2]

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

Add a point to the point list.

Parameters

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

Clear()

void Clear

(

)

Remove all points from the point list.

Point()

gz::math::Vector3d Point

(

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

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

PointCount()

unsigned int PointCount

(

)

const

Return the total number of points in the point list.

Returns

Number of points

SetColor()

void SetColor	(	unsigned int	_index,
		const gz::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	gz::math::Color Pixelcolor color to set the point to

SetPoint()

void SetPoint	(	unsigned int	_index,
		const gz::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	gz::math::Vector3d value to set the point to

Update()

void Update

(

)

Call this to update the hardware buffer after making changes.
