Can't create json animation files on mac

[glen99pl]

Modia3D is installed on my mac. It runs the tutorial and generates 2D plots (PyPlot and GLMakie), but I can’t generate 3D animations (json) for display in threejs.org.

I’ve tried many of the tutorials and tests (I know not all are supposed to generate a json file). So far, only the following have produced a json file:

• NewtonsCradle
• BouncingCones
• BouncingCapsules

However, the json files that are created don’t display properly in threejs.org. As an example, I’ve attached the json file and a short threejs animation screen capture for NewtonsCradle.

I’m not trying to use DLR_VISUALIZATION. (Library not available for mac.)

Not sure if it is related, but I get errors when I try to add the ModiaPlot_GLMakie package. Terminal output is at the below (at the end).

Here is how I’ve run the simulations:

julia> ENV["SignalTablesPlotPackage"] = "PyPlot"
"PyPlot"

julia> import Modia3D;

... Info: ENV["DLR_VISUALIZATION"] is not defined.
Therefore, no online renderer is used in Modia3D.

... Info: No renderer found -> online visualization is disabled.

[GerhardHippmann]

Thanks for reporting your issue.

Animation export can be enabled in any Modia3D model by setting animationFile="<filename>.json" in the Scene definition. As expected your example is identical to my output on Linux (except for time integration round-off errors). However, it does not display correctly in the three.js editor (Linux/Firefox) either.

I am going to investigate the problem asap. Supposedly the JSON Object Scene format has changed again like some time ago in #119.

I am not sure what your problem with GLMakie is, but it is not related to Modia3D animation export.

[glen99pl]

Thanks Gerhard.
Looking forward to seeing some animations :-)

By the way, I just tried using the DLR visualisation in a linux VM. No luck though. I guess this is because I'm running on an M1 macbook, so everything has to be compiled for ARM.

[GerhardHippmann]

Not yet fixed in Modia3D, coming soon...

[glen99pl]

Thank you - it works now!

Yes, this time the problem was not caused by three.js, but by me...
