IDL 7.0 released

IDL 7.0 is officially released today. This introduces the IDL Workbench, a cross platform, Eclipse-based development environment. My favorite features so far: it works the same on Unix platforms! in the debug perspective, you can click on any level in the call stack and examine all the variables defined at that level the outline view […]

FastDL 2.4 released

FastDL 2.4 was released today. FastDL provides a way to do cluster computing from within IDL in two different flavors: mpiDL and TaskDL. For problems which require communication between nodes, mpiDL provides an interface to the MPI standard. If you are familiar with MPI, then mpiDL should be very easy to use. It can now […]

Data vs datum

I have always been annoyed at the supposedly correct usage of the word “data”. Now I have justification to use “data” the way I want.

Vis-o-Matic

I just saw this parody of scientific visualizations, the Viz-o-Matic. Not sure if it was, but we could do this in IDL (although I’m not sure about how easy it would have been in 1993). This reminds me of the swivel.com presenter at Vis07 talking about the “bling my graph” option on swivel. Via Tufte […]

Updates to X11 for Leopard

The X.org Wiki has a page for updates for XDarwin. I was still having some issues (with CURSOR) that these updates fixed. The two lines that will do the updates are: curl -LO \ http://people.freedesktop.org/~jeremyhu/x11-apple/x11_update.sh sudo sh x11_update.sh UPDATE: it appears you should get your updates here now. I still have X problems, but things […]

LIC flow visualization

I have been searching for a better visualization for vector fields for awhile. Line integral convolution (LIC) is one of several methods that seems promising. The main references I used for my LIC implementation is the original paper “Imaging Vector Fields Using Line Integral Convolution” by Brian Cabral and Leith (Casey) Leedom and this C++ […]

Stopping xterm from launching

This is just one more piece of the X11.app puzzle in Leopard. Because /etc/X11 is gone in Leopard, the old way of configuring X11.app is obsolete. The new way is org.x.X11_launcher.plist. So the following, defaults write org.x.X11_launcher app_to_run /usr/X11/bin/xlsclients is the way to configure X11.app to not start an xterm every time it starts. UPDATE: […]

Quick Look for IDL .pro files

Quick Look is a handy feature of Mac OS X 10.5 “Leopard”. It allows you to view the contents of a file without actually opening it. I’ve found it extremely useful for browsing files. Of course, out of the box, Leopard doesn’t understand IDL .pro files because ITT VIS doesn’t provide a real application for […]

Terminal scripting in Leopard

This is an interesting article about using some of the new scripting features in Leopard’s Terminal to visually indicate which server you are logged into. I tried using Terminal again in Leopard, but soon went back to iTerm. I use iTerm with a prompt of export PS1=”\[\e]1;\h\a\e]2;\h:\w\a\e[34;1m\]\W\$\[\e[0m\] ” which uses the server name as the […]
