Detailed Description

Render a point cloud.

Constructor & Destructor Documentation

◆ RenderPointCloud()

RenderPointCloud ( const std::vector< rw::math::Vector3D< float >> &  points)

Construct RenderPointCloud adding the points specified.

Parameters
points[in] Points to draw

Member Function Documentation

◆ addPoint()

void addPoint ( const rw::math::Vector3D< float > &  p)

Adds a single line to the drawable.

Note
Each call to addLine generates an update of the display list. Use addLines to add multiple lines with only one update.
Parameters
p[in] point to add

◆ addPoints() [1/2]

void addPoints ( const std::vector< rw::math::Vector3D< double >> &  points)

Adds a collection of points.

Parameters
points

◆ addPoints() [2/2]

void addPoints ( const std::vector< rw::math::Vector3D< float >> &  points)

Adds a collection of points.

After all points are added, the display list will be updated

Parameters
points[in] List of points

◆ clear()

void clear ( )

Clears all points.

When clearing the points a new display list without points 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 points.

The influence of the alpha value depends on how opengl is configured. Calling setColor triggers an update of the display list

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

◆ setPointSize()

void setPointSize ( float  size)

Sets point size.

The thickness is forwarded to glPointSize. Default 2.0. Calling setPointSize triggers an update of the display list

Parameters
size[in] Point size
