Thanks for giving my brain one last challenge before I shut it off for the week!
Here is something that seems to work. It starts a timer that gives you x amount of time to rotate the plot. It is recording the rotation. You can then feed the recording into the second function that plays it. Obviously, a lot of numbers here are hardwired (0.5, 500) etc. Right now you get 25 seconds at a frame rate of 20fps.
To record it:
function V2 = RecordRotation
surf(peaks);
n = 500;
V = zeros(n,2);
T = timer('period',0.05,'executionmode','fixedrate',...
'TimerFcn',@captureAzEl,'TasksToExecute',n);
rotate3d on
drawnow;
start(T);
drawnow;
wait(T);
V2 = V;
function captureAzEl(src,~)
cnt = get(src,'TasksExecuted');
[V(cnt,1), V(cnt,2)] = view;
drawnow;
end
end
And to play it:
function playRecording(V)
frame_period = 0.05;
n = length(V);
T = timer('period',frame_period,'executionmode','fixedrate',...
'TimerFcn',@playRecording,'TasksToExecute',n);
rotate3d on
drawnow;
start(T);
drawnow;
wait(T);
function playRecording(src,~)
cnt = get(src,'TasksExecuted');
view(V(cnt,1), V(cnt,2));
drawnow;
end
end
And then to run the whole thing:
v = RecordRotation;
playRecording(v);
Once the figure appears, you immediately have 25 seconds. After that, it regains control and tells it how to rotate.
Next week I'll polish this up with comments etc.
