Detailed Description

PCL simple buffer visualizer main class.

Note: The idea is to offer a simple visualizer that stores and display the last X values as a curve.; The class is based on PCLHistogramVisualizer and pcl::VFHSignature308 for display.; Therefore, the number of values is limited to [2-308].

PCLSimpleBufferVisualizer() [2/2]

pcl::visualization::PCLSimpleBufferVisualizer::PCLSimpleBufferVisualizer ( const int nb_values )

inline

PCL simple buffer visualizer visualizer constructor.

Parameters

[in] nb_values the number of values stored in the buffer [2 - 308]

Member Function Documentation

addValue()

void pcl::visualization::PCLSimpleBufferVisualizer::addValue ( const float val )

inline

add a new value at the end of the buffer.

Parameters

[in] val the float value to add.

Definition at line 95 of file simple_buffer_visualizer.h.

displayValues()

void pcl::visualization::PCLSimpleBufferVisualizer::displayValues ( const int time = 1 )

inline

force display of values.

Parameters

[in] time - How long (in ms) should the visualization loop be allowed to run

Definition at line 60 of file simple_buffer_visualizer.h.

setAutomaticBackgroundColorControl()

void pcl::visualization::PCLSimpleBufferVisualizer::setAutomaticBackgroundColorControl	(	const bool	value = `true`,
		const float	threshold = `0.0f`
	)

inline

set background color handling mode.

Note: The point here is to change the background to orange when the latest value is under a threshold.

Parameters

[in]	value	if true, automatic mode is enabled. Else, background will be white
[in]	threshold	value that triggers the background to turn orange if the latest value is lower

Note: This functionality does not work yet at time of commit (see http://dev.pointclouds.org/issues/829)

Definition at line 134 of file simple_buffer_visualizer.h.

setManuallyManageYScale()

void pcl::visualization::PCLSimpleBufferVisualizer::setManuallyManageYScale ( const bool value = false )

inline

set Y scale policy.

Note: If set to true, the minimal and maximal Y values are kept forever.; If set to false, the Y scale is automatically adjusted to the current values (default).

Parameters

[in] value boolean that enable or disable this policy
