## Detailed Description

This 3D Widget defines a collection of clouds. :

Note
  In case there are four channels in the cloud, fourth channel is ignored.

## Constructor & Destructor Documentation

## § WCloudCollection()

cv::viz::WCloudCollection::WCloudCollection | ( |  | ) |

## Member Function Documentation

## § addCloud() [1/2]

void cv::viz::WCloudCollection::addCloud | ( | InputArray | cloud,
|  | InputArray | colors,
|  | const Affine3d & | pose = `Affine3d::Identity()`
| ) |  |

Adds a cloud to the collection.

Parameters

  cloud | Point set which can be of type: CV_32FC3, CV_32FC4, CV_64FC3, CV_64FC4.
  colors | Set of colors. It has to be of the same size with cloud.
  pose | Pose of the cloud. Points in the cloud belong to mask when they are set to (NaN, NaN, NaN).

## § addCloud() [2/2]

void cv::viz::WCloudCollection::addCloud | ( | InputArray | cloud,
|  | const Color & | color = `Color::white()`,
|  | const Affine3d & | pose = `Affine3d::Identity()`
| ) |  |

Adds a cloud to the collection.

Parameters

  cloud | Point set which can be of type: CV_32FC3, CV_32FC4, CV_64FC3, CV_64FC4.
  color | A single Color for the whole cloud.
  pose | Pose of the cloud. Points in the cloud belong to mask when they are set to (NaN, NaN, NaN).

## § finalize()

void cv::viz::WCloudCollection::finalize | ( |  | ) |

Finalizes cloud data by repacking to single cloud.

Useful for large cloud collections to reduce memory usage
