Does this mean that we are abandoning the idea to have -g determine *how* out put is printed (i.e., shell-script style) and use other flags to determine *what* is printed? Michael C. Michael Barton Director, Center for Social Dynamics & Complexity Professor of Anthropolog

While I understand the problems, if we revert it, it will be much worse. The initial z-exag will be set to 1000 for latlon and even a value of 1 will be enormously too big. This is why I tried to improve it. The previous way it was working was even more arbitrary than it is now. It is making no

Thanks for the ideas Hamish. I'm pretty sure that there is a conversion from geographic coordinates in xyz to arbitrary screen coordinates in the OGL code section. I understand what Helena is hoping for, and this would indeed be the ideal. To me, this 'natural' ratio between xy and z should have
