Detailed Description

Render drawing a collection of lines.

Constructor & Destructor Documentation

RenderLines()

RenderLines

(

const std::vector< rw::geometry::Line > &

lines

)

Construct RenderLine adding the lines specified.

Parameters

lines

[in] Lines to draw

Member Function Documentation

addLine()

void addLine	(	const rw::math::Vector3D<> &	v1,
		const rw::math::Vector3D<> &	v2
	)

Adds a single line to the drawable.

Parameters

v1	[in] Start point for line
v2	[in] End point for line

addLines()

void addLines

(

const std::vector< rw::geometry::Line > &

lines

)

Adds a collection of lines.

Parameters

lines

[in] List of lines

clear()

void clear

(

)

Clears all lines.

When clearing the lines a new display list without lines will be generated.

draw()

void draw ( const rw::graphics::DrawableNode::RenderInfo &  info, rw::graphics::DrawableNode::DrawType  type, double  alpha  ) const

virtual

Parameters

info	[in] state and rendering specific info
type	[in] the drawtype which is being used
alpha	[in] the alpha value to render with

Implements Render.

setColor()

void setColor	(	float	r,
		float	g,
		float	b,
		float	alpha
	)

Sets the color of the lines.

The influence of the alpha value depends on how opengl is configured.

Parameters

r	[in] red [0;1]
g	[in] green [0;1]
b	[in] blue [0;1]
alpha	[in] alpha [0;1]

setThickness()

void setThickness

(

float

thickness

)

Sets thickness of the line.

The thickness is forwarded to glLineWidth. Default 1.0.

Parameters

thickness

[in] Thickness of the lines
