3d visualisation win7 in nightly (once again)

3d visualisation win7 in nightly (once again)

Nov-27-14 15:51:41

Hey,

i've downloaded the nightly today (1.9.2+dev (r23574) to get a test run on Modelica 3D-Mechanics.
I'd love to have some visualisation of the models and I did read what I had found on google and this forum.

So far followed the User Guide, installed Python and PyGTK run the dbus-server.py. This isn't the problem, I guess.

But there seem to be translation/compile problems when using modelica3d library inside of a model (without modellica3d it did work in OMCEdit.

So far I did run as said in the forum.

Code:


loadModel(Modelica);

loadModelica3D();

loadString("model visualizemodel

  extends Modelica.Mechanics.MultiBody.Examples.Elementary.DoublePendulum;

  inner ModelicaServices.Modelica3D.Controller m3d_control;

end visualizemodel;"); getErrorString();

simulate(visualizemodel, startTime=0.0,stopTime=10.0);

which raises some errors in modelica to C translation (listed without mingw errors and stripped paths for easier reading). and the following build of curse fails.

Code:


[package.mo:15:3-18:12:writable] Warning: Ignoring record component:

  ExternalObject ModelicaServices.modbus.Connection conn;

when building record the constructor. Records are allowed to contain only components of basic types, arrays of basic types or other records.

[package.mo:15:3-18:12:writable] Warning: Ignoring record component:

when building record the constructor. Records are allowed to contain only components of basic types, arrays of basic types or other records.

so I thought I'd start with the first two warnings and make a class out of the ModelicaServices.Modelica3D.State. Well that also didn't work also.

Code:

It seems that the first error falls to an unfixed error which is listed in trac as #2319?
But in the past the modellica3d seems to work under windows... I had the same problems with the official 1.9.1. build.

Is somebody with some experience able to help me?

ps: here is the mingw error (for the 'record' version), if the problem should be hidden there...

Re: 3d visualisation win7 in nightly (once again)

Ok, got forward a little.

- First, there is a github, where the current modellica3d is placed.
You need to follow the instructions in that file of the repository.
- Then the "record State" must be removed completely to get this to work (see below).

Now the dbus-server opens it's window, but of curse nothing is displayed. All Shapes which are created by the Mechanics Library have length or other sizes set to zero. I've digged into the dbus-messaging. And followed it back to Modellica3D.PartialShape. Lengh is set to zero there when it is initalised. It seems to happen with the Mechanics.Multibody.Visualiser models. This may be the cause of the messages which appear while translation.

Code:

Due to the missing loadModelica3D() call in OMEdit I see no possibility to debug this problem. Does anybody has an Idea how to debug this (using the OMShell or other things?)

Here is my new package.mo: packagemo.zip

OK, got it!

right before weekend ^^

Just use the provided package.mo.

It was an initialisation problem of the shape sizes. the dbus part sent the values to early (thus they were zero). Sending in the algorithm part did fix it.

I'll have weekend and if I won't forget I'll provide a patch which does this with one step...
