const PointT& pcl::PCLBase::operator[] ( size_t  pos) [inline, inherited]

Override PointCloud operator[] to shorten code.

Note:
this method can be called instead of (*input_)[(*indices_)[pos]] or input_->points[(*indices_)[pos]]
Parameters:
posposition in indices_ vector

Definition at line 178 of file pcl_base.h.

void pcl::Filter::setFilterFieldName ( const std::string &  field_name) [inline]

Provide the name of the field to be used for filtering data.

In conjunction with setFilterLimits, points having values outside this interval will be discarded.

Parameters:
field_namethe name of the field that contains values used for filtering

Definition at line 103 of file filter.h.

void pcl::Filter::setFilterLimits ( const double &  limit_min,
const double &  limit_max

Set the field filter limits.

All points having field values outside this interval will be discarded.

Parameters:
limit_minthe minimum allowed field value
limit_maxthe maximum allowed field value

Definition at line 120 of file filter.h.

void pcl::Filter::setFilterLimitsNegative ( const bool  limit_negative) [inline]

Set to true if we want to return the data outside the interval specified by setFilterLimits (min, max).

Default: false.

Parameters:
limit_negativereturn data inside the interval (false) or outside (true)

Definition at line 139 of file filter.h.

void pcl::PCLBase::setIndices ( const IndicesPtr indices) [inline, inherited]

Provide a pointer to the vector of indices that represents the input data.

Parameters:
indicesa pointer to the vector of indices that represents the input data.

Definition at line 105 of file pcl_base.h.

void pcl::PCLBase::setIndices ( const PointIndicesConstPtr indices) [inline, inherited]

Provide a pointer to the vector of indices that represents the input data.

Parameters:
indicesa pointer to the vector of indices that represents the input data.

Definition at line 116 of file pcl_base.h.

void pcl::PCLBase::setIndices ( size_t  row_start,
size_t  col_start,
size_t  nb_rows,
size_t  nb_cols 
) [inline, inherited]

Set the indices for the points laying within an interest region of the point cloud.

Note:
you shouldn't call this method on unorganized point clouds!
Parameters:
row_startthe offset on rows
col_startthe offset on columns
nb_rowsthe number of rows to be considered row_start included
nb_colsthe number of columns to be considered col_start included

Definition at line 132 of file pcl_base.h.

virtual void pcl::PCLBase::setInputCloud ( const PointCloudConstPtr cloud) [inline, virtual, inherited]

Provide a pointer to the input dataset.

Parameters:
cloudthe const boost shared pointer to a PointCloud message
