[Octave-bug-tracker] [bug #65422] Octave patch does not plot patch if points create a straight line

[Markus Mützel]

Follow-up Comment #5, bug #65422 (group octave):

IIUC, you are comparing the time that it takes to create a single patch object
to the time it takes to create 1001 line objects.
Obviously, creating 1001 line objects will take longer.

If you compare the time for creating 1 patch object to the time for creating 1
line object, the line object is faster here.
E.g., after having run your example:

>> tic, h_tri=patch('Vertices',     vert(:,2:end),'Faces',
faces,'FaceColor',[1 0 0],'EdgeColor', [1 0 0],'FaceAlpha', 0.2, 'LineWidth',
1 ); toc
Elapsed time is 0.0061202 seconds.
>> tic, l=line(xd(:),yd(:),zd(:), 'color', 'r'); toc
Elapsed time is 0.00542593 seconds.


Anyway, this discussion is off-topic to this report. Please, ask questions
about how to use Octave on the discourse forum:
