My conference travels: Scipy 2011 and HBM 2011

The Scipy 2011 conference in Austin

Last week, I was at the Scipy conference in Austin. It was really great to see old friends, and Austin is such a nice place.

The Scipy conference was held in UT Austin’s conference center, which is a fantastic venue. This is the ...

Windows binaries for the scientific Python ecosystem

I just realized yesterday that Christoph Gohlke has a repository of binary installers (.exe) for Windows 32 and 64bit with almost all the scientific Python packages that you can dream of:

Multitouch with VTK (and MedINRIA and Mayavi)

If the videos on this post are not showing, click through to see them.

A colleague of mine, Pierre Fillard, has just integrated multitouch in the next generation of the VTK-based medical imaging software MedINRIA. The nice thing is that it works on an Apple laptop out of the box ...

Mayavi: Representing an additional scalar on surfaces

We have been getting a few questions on the enthought-dev mailing-list on how to represent an additional information on a surface with Mayavi, using color not given eg by the elevation. A recent post on his blog by Didrik Pinte shows the problem quite well:

This problem can be seen ...

New Mayavi release

A week ago, the Peter Wang released a new version of the Enthought Tool Suite (ETS). With it came a new version of Mayavi2.

Prabhu and I have been horribly busy we real life, and I had the bad feeling that we were not giving enough love to Mayavi. I ...

Using Python, Scipy, ETS, … to implement art

The Aikon project has just been slashdotted.

The project is about implementing a robotic artist, with a special artistic touch:

The Co-principal investigator, Patrick Tresset, gave a talk at the French Pycon this year and I was simply flabbergasted by the project. It is amazing to mix together art and ...

Mayavi: 2 videos of tutorial-like presentation

I gave a presentation on Mayavi in the Python for science seminar organised by Fernando Perez at Berkeley. I was loudmouth and obnoxious as usual, and unfortunately for me, I was recorded.

More seriously, Jeff Teeters has filmed the presentation and recorded the sound was a microphone I was wearing ...

Minimum spanning tree

Gary Ruben came up with the excellent idea of visualizing the minimum spanning tree of a Delaunay tesselation in addition to Delaunay tessalation itself. After he sent me his code, I spent some times playing with it, because I found out that, with the right choice of visualization parameter, it ...

Extracting the data from the Delaunay triangulation

Gary Ruben just asked me if it was possible to retrieve the triangulation information from my previous Delaunay example. Actually the reason I came up with this example is that Emanuelle Gouillart, my partner[*], needed to do Delaunay triangulation on some data. She was kind enough to extract that code ...

Mayavi image of the … month

Tonight I sat down and played a bit with VTK’s Delaunay tessalation filter. I wanted to inspect the local structure of a graph created by Delaunay tessalation of random points. To see better the structure, I selected a slab of the resulting unstructured grid. I think the image is ...
