but holes at N and S poles where one used to be)!! suitable for playing
with. I assume I'll either (1) have to paint over the whole thing, somehow
retaining the handy lat. and long. lines, then draw in the Cindu land
forms-- very challenging I suspect, or (2) make paper gores (with pre-drawn
land forms) to glue on, equally challenging I suspect. The Zompist website
has instructions for doing that, which I've tried, but getting the curvature
right is a mystery. I might try tracing outlines from the existing ones???
Does anyone know the geometrical qualities of a sphere? Are there formulae
for drawing those triangular shapes with curved sides? They are all
presumably arcs, but it would require a HUGE compass....or are they just
regular isosceles triangles (I doubt)?? Is there perchance some free or
inexpensive software that would help? I can do a lot of trial and error, of
course..... Maybe I should get in touch with the geography dept. at one of
the local colleges?
Has anyone ever tried such a project? Any suggestions or hints would be very
welcome (reply privately I think).
