Detailed Description

A 2D ellipse or 3D ellipsoid, depending on the size of the m_cov matrix (2x2 or 3x3). The center of the ellipsoid is the "m_x,m_y,m_z" object's coordinates. In the case of a 2D ellipse it will be drawn in the XY plane, for z=0. 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 one of the eigen value of the covariance matrix of the ellipsoid is null, ellipsoid will not be rendered.
