I recently became stuck trying to create an animation which consists of a smooth rotation of a viewpoint around the Lorenz attractor. Methods I use for changing viewpoints with respect to surface objects were creating jerky, lagging animations when applied to my line plot.
This will work for any 3D line plot:
plot3(x,y,z); axis vis3d fps = 60; sec = 10; vidObj = VideoWriter('plotrotation.avi'); vidObj.Quality = 100; vidObj.FrameRate = fps; open(vidObj); for i=1:fps*sec camorbit(0.9,-0.1); writeVideo(vidObj,getframe(gcf)); end close(vidObj);
This results in the following smooth animation:
