Hi, I would like to implement the fly-through effect as shown in this nice example: https://ch.mathworks.com/help/matlab/visualize/example-moving-the-camera-through-a-scene.html

I've attached 4 files with my data variables. First I created a figure from hm variable by using surf function: surf(hm); Then, I defined an animated line from x,y and z variables and displayed on the hm figure as follows:

curve = animatedline; curve.LineWidth = 6; curve.Color = [ 1 0 1];

for i=1:length(x) addpoints(curve, x(i), y(i), z(i)); drawnow; end

Then, I wanted to implement the fly-through effect so that the camera will move along the line. I tried this code piece I took from the example above and I slightly modified it:

for i=1:length(x) campos([(x(i) -5),(y(i)-5),0]) camtarget([x(i),y(i),z(i)]) drawnow end

But the camera doesnt move as I intended.

what am i doing wrong?
