2Dfied editors do not work with ati [message #563878]

Hi,

I always had problems with 3Dfied editors(like the uml examples). The projected figures were not displayed properly: All labels were stretched, looking too big. Furthermore dropping another diagram (activity diagram e.g.) in the Multieditor was not possible. Today I've made an update of the gef3d sources (previous update was like 3 weeks ago). Unfortunately, now the uml-example editors are not working at all. The editor opens, but the 3d-area is just white (the palette is displayed properly). Same for the multieditor. Using my custom 3D-Graph-Editor (not 3dfied), all vertieces are shown, but their labels are not visible. Drag and drop in the multieditor is however not working.

I think that has something to do with the drawing of 2D-objects in a 3D scene. Here is what the console outputs, while opening a uml class diagram in the 3d editor:

I' ve observed this behavior on the following configurations:

Windows Vista; ATI Mobility Radeon X1400,
Windows 7, ATI Radeon HD 2400 Pro,
both with catalyst 10.1 drivers, FBO supported

So, is this a known issue, or maybe an ATI-Related problem?

Best regards,

Kamil

Kamil,

the render mechanisms of GEF3D were dramatically changed in the last
weeks. Kristian has implemented a whole new technique for rendering 2D
content (and 2D fonts as well). You may have a look at the GEF3D blog.
Draw3D now heavily uses FBO, and almost no textures are used anymore.

These hardware/OpenGL driver issues are a real pain, especially since
we (Kristian and I) both have the same hardware (MacBook Pro). There is
a page with a list of tested graphics cards
( http://www.fernuni-hagen.de/se/personen/pilgrim/gef3d/requir ements.html
), I have to move that page to the GEF3D wiki one day. There are some
ATI cards listed, but this list is rather old and I do not know if they
are still working with the latest version.

Your console log doesn't show any errors or exceptions... weird. Since
"only" the 2D content isn't working, I assume it has something todo
with FBOs. It seems as if the ATI driver is a little bit problematic.
Hmm... Kristian, do you have any ideas?

Cheers

Jens

Hi Kamil,

I'd like to try and nail down that problem for you. It may or may not
be related to the latest changes in the 2D renderer. Both of your video
cards should support all features necessary to run GEF3D, but maybe
there is some difference in the way they support the spec. I am using
an NVidia card, but have access to a machine with an ATI card. I'll try
the standard UML examples (which is what you are using?) on that
machine and report the results here.

Best regards
Kristian

Hi again,

I see multiple problems in your report:

1. This is odd, but I guess we don't need to adress this further at
this time because now it doesn't work at all for you anymore. So first
things first:

2. I have seen this behavior before. Could you please try and move the
camera around (by clicking and dragging while the camera tool is
active) and tell me whether you see flickering (sometimes you see the
diagram, sometimes everything is white).

> Using my custom 3D-Graph-Editor (not 3dfied), all vertieces are shown,

May be related to 2., so let's see if fixing that fixes this as well.

> Drag and drop in the multieditor is however not working.

This seems to be an entirely different problem and may be related to
your setup. The multi editor uses the plugin registry to discover which
editors are suitable for a certain diagram type. For this it matches
the file extension against all registered editor extensions (see
org.eclipse.gef3d.ext.multieditor.AbstractMultiEditor#findNe stableEditorClasses(IEditorInput).
If a registered editor matches the file extension and implements the
INestableEditor interface, it is added to the multi editor. Maybe for
some reason this mechanism is broken on your runtime instance, so if
you want to debug, this would be a point to start. It would be really
cool if you could check whether any matching editors are found in this
method and post your results here.

Best regards
Kristian

Hi,

i still have have the drag/drop and flickering problems... Maybe a newer version of the lwjgl renderer would help.

The LWJGL 2.3 release fixes some issues with ATI 10.x drivers (See http://www.lwjgl.org/index.php).

However, the update site (http://lwjgl.org/update) offers only version 2.2.1. and a manual installation is not supported...

So when does the update site is going to be updated :) or should i install the new version of lwjgl manually (how?).

cheers
Kamil

The LWJGL update site is maintained by the LWJGL guys, I only wrote the
initial plugin code and contributed it, but I have no access to the code
at LWJGL.org. I asked Brian Matzon (one of the LWJGL developers) whether
he could update the plugin to 2.5 (the latest release) as well, see
http://lwjgl.org/forum/index.php/topic,3398.0.html

It should be possible to simply exchange the JAR and library files in
the LWJGL plugin. As a hack (for testing purposes) you can try to
replace the following files with newer versions (assuming the overall
structure of LWJGL hasn't been changed):

org.lwjgl_2.2.1/jinput.jar
org.lwjgl_2.2.1/lwjgl.jar

Depending on your OS:
Linux:
org.lwjgl_2.2.1/native/linux/*
or Mac OS X
org.lwjgl_2.2.1/native/macosx/*
or Windows, 32 bit
org.lwjgl_2.2.1/native/win32/*
or Windows, 64 bit
org.lwjgl_2.2.1/native/windows/*
etc.

Maybe you could check whether there are different files or if only the
files itself were updated. You will find all these files in the orignal
LWJGL distribution, actually the plugin does only enclose these files
into a bundle. But again: THIS IS ONLY A HACK!

Cheers,

Jens
