why always said: An error occurred while drawing the scene? need help!

matlab error: An error occurred while drawing the scene

[Walter Roberson]

We need to know more about what you were doing, and which MATLAB version, and which operating system.

[Mike Garrity]

That message generally means that something happened on the thread that's driving the graphics card. It should be followed by some additional details about what exactly happened. For example, the graphics card may have run out of memory.

The first thing I would do is this:

opengl info

This will tell you what type of graphics card you have, and what version of the driver you have installed.

Another option is this:

opengl software

That will tell MATLAB to stop trying to use the graphics card, and use a software version of the OpenGL library.

Thanks! It works.

I tried that and got this message back in the command:

>> opengl software
Error using opengl
Switching to software OpenGL rendering is not supported on the Mac platform.

What else can I do?

I am having this issue now in 9.8.0.1323502 (R2020a) in an app built with App Designer. It happens randomly as I use the app. When it happens, I have to restart Matlab. Quite frustrating and new for me.

I can second Kristoffer here, also getting:

Warning: An error occurred while drawing the scene: Error in json_scenetree: Could not find node in replaceChild

@Kristoffer WalkerMaybe u can try this command opengl software before starting APP Designer.

The issue might be due to using hardware OpenGL. This occurs since Intel HD 2000 hardware and any of its drivers are not supported with MATLAB 8.4(R2014b) or later.

The issue does not occur in MATLAB R2014a or other previous releases because those makes use of the previous graphics engine HG1 which supported the Intel HD 2000 hardware. However, from MATLAB 8.4(R2014b), a new graphics engine HG2 was unveiled and this does not support Intel HD 2000 hardware for any of its drivers.

As Mike suggested, you can try :

    opengl software

Thanks! It works.
