Hello,
I am trying to picture a sphere in perspective using the ellipseArc function
Here is my MWE : it seems like ellipseArc can't properly complete the
ellipse arc for angles 180 to 360°. Unless I'm doing something wrong ?
%%%%%%%%%%%%%%%%%%%
% 3D earth with girth
figure(1);clf
drawCircle(0,0,2,'Color','k');
axis square
hold on;
%drawEllipseArc([0,0,2,.1,0,0,180],'Color','k','LineStyle','--');
drawEllipseArc([0,0,2,.1,182,350],'Color','k');
hold off
axis off
%%%%%%%%%%%%%%%%%%%%

You might want to edit drawEllipseArc.m
and change the 60 on line 126 to a bigger number so that you get a smother curve.
I tried 600 and it made a nice picture from your code.
