Detailed Description

generic class that covers one single point cloud of different possible types provided by the Point Cloud Library (PCL).

The possible types are compatible to PCLPoint and described in ito::tPCLPointType:

ito::pclXYZ: x, y, z ito::pclXYZI: x, y, z, intensity ito::pclXYZRGBA: x, y, z, color (red, green, blue, alpha) ito::pclXYZNormal: x, y, z, normal_x, normal_y, normal_z, curvature ito::pclXYZINormal ito::pclXYZRGBNormal

The specific type is saved in the member m_type whereas different members are available each one holding a shared pointer to the point cloud of one specific type. Only one of those shared pointers can contain a valid point cloud.
