App designer 3d in GUI - Rotate3d ?

17 次查看(过去 30 天)
I've made an app with a plot3 plot. I just can't make my plot rotate by using the mouse - I've tried using "rotate3d on" but it does not fix it. Any suggestions?

I was able to do this using the following to control the UIAxes that I added to my AppDesigner app.
rotate3d(app.UIAxes,'on');
Note that this will turn the rotation permanently on, so I recommend having a toggle button to switch it on and off. Otherwise, every time you mouse over the axes, it will try to rotate.
Based on this documentation, however, interactivity with plots is not officially supported, so you may see some improvements/changes to this in future releases. https://www.mathworks.com/help/matlab/creating_guis/graphics-support-in-app-designer.html

If you look for a solution for how to interactively rotate an image in 2D, here are some results after interaction with the helpfull MathWorks staff.
The best option for me was to activate the "rotate" tool, i.e. rotate3d, of the toolbar and rotate the image in 2D only by using the left and right arrow keys. Once you touch the image with the mouse or the trackpad, however, it will tilt in 3D.
The camroll of cameratoolbar does 2D rotation, but cameratoolbar in not functional anymore in Apps – as Markus remarked –, even if you modyify the code in m-files.
You might want to design the interface not as an App, but loosing some features of Apps.
Adding a slider and a SliderValueChanged callback has the unwanted effect of seeing the rotation outcome only after releasing the mousedown of the slider.
The use of the SliderValueChanging callback should provide continuous rotation as the slider is moved, but the graphic rendering is slow when changing the first value of app.UIAxes.View.
Here is some code to play with (save it as "rotateApp_dev.m" and run it from the Editor). Hope this helps.
classdef rotateApp_dev < matlab.apps.AppBase
% Test how to interactively rotate an image in the plane; the problems to
% solve where that image rotation with the current interactive tools

I have a globe plotting function that I've used for years which rotates very smoothly in a regular figure window using rotate3d. I echo Markus Leuthold's observation that in an app designer UIAxes object the rotation is much less responsive (at least in 2019a), to the point of being unusable. Also the lines don't render correctly in App Designer.
Here's an image from the UIAxes version. Note the graphics articfacts, and the missing lines.
And here is one from a normal figure window:

Hod did you plot a 3d graph in app designer?

The feature is available only from MATLAB 2017B (UIAxes supports 3D plots since then).
