how to draw a 3D angle in MATLAB

Question

I have three angles who's values are 0.0 , 94.3750 , -0.5625. Starting from those 3 angles, how can I draw an 3D angle in MATLAB? Thanks in advance

Answer 1

You can try something like this:

angles=abs(pi/2*rand(3,50)); %data
figure
for ii=1:size(angles,2)
quiver3(0,0,0,cos(angles(1,ii)),cos(angles(2,ii)),cos(angles(3,ii))) %plot arrow
view(30,30) %or Matlab will choose it arbitrarily
axis([0 1 0 1 0 1]) %just for convenience
pause(.2)
end

and if you want to save the figures in order:

angles=abs(pi/2*rand(3,50));
figure(1)
for ii=1:size(angles,2)
quiver3(0,0,0,cos(angles(1,ii)),cos(angles(2,ii)),cos(angles(3,ii)))
view(30,30)
axis([0 1 0 1 0 1])
pause(.2)
file_name= sprintf('%0.4d_%s_%s',ll);
print('-f1',file_name,'-dpng')
close(1)
end
