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

Member Function Documentation

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

Adds a cloud to the collection.

Parameters
cloudPoint set which can be of type: CV_32FC3, CV_32FC4, CV_64FC3, CV_64FC4.
colorsSet of colors. It has to be of the same size with cloud.
posePose of the cloud. Points in the cloud belong to mask when they are set to (NaN, NaN, NaN).
void cv::viz::WCloudCollection::addCloud ( InputArray  cloud,
const Color color = Color::white(),
const Affine3d pose = Affine3d::Identity() 
)

Adds a cloud to the collection.

Parameters
cloudPoint set which can be of type: CV_32FC3, CV_32FC4, CV_64FC3, CV_64FC4.
colorA single Color for the whole cloud.
posePose of the cloud. Points in the cloud belong to mask when they are set to (NaN, NaN, NaN).
void cv::viz::Widget3D::applyTransform ( const Affine3d transform)
inherited

Transforms internal widget data (i.e.

points, normals) using the given transform.

Parameters
transformSpecified transformation to apply.
template<typename _W >
_W cv::viz::Widget::cast ( )
inherited

Casts a widget to another.

// Create a sphere widget
viz::WSphere sw(Point3f(0.0f,0.0f,0.0f), 0.5f);
// Cast sphere widget to cloud widget
viz::WCloud cw = sw.cast<viz::WCloud>();
Note
3D Widgets can only be cast to 3D Widgets. 2D Widgets can only be cast to 2D Widgets.
