class mrpt::opengl::CEllipsoid3D

Overview

A 3D ellipsoid, centered at zero with respect to this object pose.

The color is determined by the RGBA fields in the class “CRenderizable”. Note that a transparent ellipsoid can be drawn for “0<alpha<1” values. If any of the eigen values of the covariance matrix of the ellipsoid is zero, nothing will be rendered.

Please read the documentation of CGeneralizedEllipsoidTemplate::setQuantiles() for learning the mathematical details about setting the desired confidence interval.
