MATLAB: Question about ‘view’ function

distance from viewer to object-view function

Hi:

I have a question about 'view' function.

https://www.mathworks.com/help/matlab/ref/view.html

as can be found in the documentation above, the view is determined by two angles. however, even using the same angle, if you look at the object from different distance, the view would still have difference (zoom in/out effect). so, my question is that, does Matlab have anyway to control this distance? or it is a default number?

Thanks!

There are a number of options available. One that may do what you want is the 'CameraPosition' (link) axes property. There are several others you can explore that are in the View section of the documentation.

I believe biograph needs to be updated to work properly in Live Scripts (MLX files). One workaround is to use a regular script (M file) instead.

This is the waned behavior of the automatic view angle mode.

h = polar(1,1,'*r')
set(gca, 'CameraViewAngleMode', 'manual', 'CameraTargetMode', 'manual', ...
         'CameraPositionMode', 'manual');
for k = linspace(0, pi, 100)
  set(gca, 'CameraUpVector', [sin(k), cos(k), 0]);
  pause(0.01);
end

By the way: 'View' is an obsolete property for many years now. Do not use it.
