In fact, Eigen was conceived for 3D calculations ;) In fact Benoit Jacob (eigen's author) use it for the 3D molecule viewer in kalzium, and marble's author use it as well for showing earth. As for the kdchart and 3d, and the usefullness of it, I don't know, so I won't say anything. -- Cyrille Berger _______________________________________________ koffice-devel mailing list koffice-devel@kde.org https://mail.kde.org/mailman/listinfo/koffice-devel
