Hi All,
Just to give some news about Mondrian. Together with colleagues from
Bern, Lille and Santiago, I have been working on this visualization
engine for quite some times. Although it contains some important bugs
(e.g., popupView) it is fairly stable and usable. The current version
is 2.0-beta.7.
Mondrian is slowly maturing. A short summary of the discussion I had
with Doru and Stéphane today.
Some of the features I would like to see in for Version 3.0 are:
- scalable spring layout (also known as force based layout): this
is a very simple and nice layout that produces amazing results
- add layers: embedding a rendering or a part of it in a layer.
Layers could then be iteratively activated and desactivared. The idea
is to enable the construction of scripts in a very iterative and
incremental way.
- having a small core embeddable in your application
- making Mondrian load graphiz scripts
- having a better help system (à la ProfStef)
- dedicated chapter for Pharo By Example Volume 2
- exporting as PDF
- anti-aliasing
This probably will not happen today or tomorrow, but I just feel
necessary to share this roadmap with you. Some other features are
wanted. Using Rome is one. Open GL is another. There are plenty of
rooms for a very cool visualization engine.
Probably during the holiday period I will consolidate the current
version by fixing remaining bugs and produce 2.0.

Fun to hear that, because the initial Mondrian code I wrote for
Squeak/Pharo had layers.
Ha, I was waiting for that :).

this is a nice idea Also an efficient spring layout with edges
that automatically avoid nodes and that are optimized for minimal
crossings was implemented by Julien Fierz and part of the code at some
point in time.
I did not know this one.

The fisheye layout was not using Mondrian, also because he had some
animations on it.
Mondrian was used in the context and receiver inspector to visualize
the relationship between the objects.
The layout was based on GraphViz.
I doubt that you can get it any faster with the technology built into
Pharo, because in the end the drawing works through primitives and the
aliasing is just a flag that is set. Maybe something based on Cairo or
OpenGL would be faster?
I suppose.
One thing I was thinking of was to trigger the anti-aliasing at least
when exporting the picture and not for regular visualizations. The
idea is that when you export it you have time and you typically want
better quality (paper, report or just bragging :)). That should be
doable now.

Julien used it in his back-in-time debugger to visualize flow of
data
in a (potentially large) graph of objects. Also the

Indeed. One that can render hundreds of edges.

HI Alexandre, what is the current status of Mondrian on Squeak? I've
always been intrigued by Mondrian, what would be the best approach for
getting it going on Squeak?
I am mostly interested using Mondrians rendering and input-event
handling inside my own widgets, not OB or other windowing tools. How
hard would it be to extricate just the Form-drawing and
input-capability of the Mondrian core from the OB window widgetry that
seems to be included in the package (at least, the last time I
looked)?

Hi Chris,
The core of Mondrian has no relationship with OB.
The rendering of Mondrian only depends on Canvas. By default, when you
say "view open" a window with a canvas is created and the canvas is
passed to Mondrian.

Doru

Hi Chris,
I haven't recently tried to install Mondrian on Squeak. If it does not
work, no much should be missing I believe. There is nothing in Pharo
which is a crucial requirement. If you wish to see Mondrian on Squeak,
then I can help to make it work.
I am mostly interested using Mondrians rendering and
input-event
handling inside my own widgets, not OB or other windowing tools. How
hard would it be to extricate just the Form-drawing and

seems to be included in the package (at least, the last time I
looked)?
As Doru said, there is no relationship between Mondrian and OB.
Mondrian was dependend on OB some times ago principally for the text
input lower pane. But not anymore.
If you have any question on how to use Mondrian, please ask.
Cheers,
Alexandre
