## Detailed Description

This 3D Widget represents normals of a point cloud. :

## Constructor & Destructor Documentation

## ◆ WCloudNormals()

cv::viz::WCloudNormals::WCloudNormals | ( | InputArray | cloud,
|  | InputArray | normals,
|  | int | level = `64`,
|  | double | scale = `0.1`,
|  | const Color & | color = `Color::white()`
| ) |  |

Constructs a WCloudNormals.

Parameters

  cloud | Point set which can be of type: CV_32FC3, CV_32FC4, CV_64FC3, CV_64FC4.
  normals | A set of normals that has to be of same type with cloud.
  level | Display only every level th normal.
  scale | Scale of the arrows that represent normals.
  color | Color of the arrows that represent normals.

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