Both my talk proposals were rejected this year :(. The reasons given for both of them were valid though. The talk on “VTK Designer” was rejected because it was already done last year. Valid point.The talk on GCF was rejected because it was too specific. Valid point again. The FOSS.IN team is really doing a…

I just uploaded GCF 1.0.573, here is the link: http://vcreatelogic.com/oss/gcf/index.html. The uploaded GCF is updated from the version I had sent for the contest. I have also updated the documentation a bit. I hope the new documentation makes better sense than the old one.

“Generic Component Framework” the foundation on which VTK Designer 2 sits, won the 3rd place in the QtCentre Contest. When the finalists were put up I practically gave up because the other entries were mature projects while GCF had about 2-3 months of effort (I had sent GCF build 102 for the contest today we…

Enabling haptic transformations is so simple in VTK Designer now. All you have to do is to set some properties for haptic actors in your scene; and you are ready to go !. See how it works in this video. http://www.youtube.com/watch?v=dRC9BpXec7s The script was pretty simple and small !

We have managed to get the PHANToM Omni working with VTK Designer (and VTK ofcourse) using SensAble Technology’s Open Haptics toolkit. They have some some pretty amazing work. Making VTK work with the haptic device was not all that complicated. We just had to read a bunch of materials (read documentation, sample code etc) and…

Unfortunately the vendor of the hardware device I bought last week does not support Windows Vista. So I had to switch back to Windows XP Professional. It sucks, but then I really did not want to blow away all the effort (and money) that went behind getting the device just because of an OS problem.…

Highly inspired by Microsoft Office, I created a very simple menu widget for VTK Designer and called it “Menu Strip”. No, it is not similar to ribbon, although it is inspired by it. I am getting mixed feedback from friends, users and colleagues about it. Lots of work left before it can be called polished.

Twenty three days and a couple of thousand dollars later, the hardware device arrives :). Anyways, I have to clear some more hurdles before which I can actually begin to use it. a) I need a 15A switch and not the 5A switch that I have in the office at the moment :(. So I…

“Best penalty kick ever! 😀” on Google Video It’s funniest penalty kick i’ve ever seen!

Well, I have gotten a little somewhere with Marble 🙂 I must say Marble is written exceptionally well. Khudos to the guys that wrote it. Before I go further, here is a screenshot of Marble widget and navigator in VTK Designer 2. And I want to go from here to a more fancy avatar than…

I read about KDE 4 Beta 1 release yesterday and noticed the enticing Marble. A Google SOC project which I am sure will have a huge adoption in the open source world. I encourage you to download and use Marble, It compiles with Qt 4.3, you dont necessarily have to have KDE 4 running on…

We guys at our company decided to import a piece of hardware to understand, learn and generally play around with. The decision to import was made when all vendors in India told us that they dont have it with them. Anyways, once the decision was made we were made to understand the procedure in making…

I was reading a bunch of materials on center line algorithms. These algorithms essentially evaluate a line that passes through the center of a tunnel. Most of the algorithms that I was reading works on 3D Image data sets, I was searching for something that works on a polygonal model of a 3D Tunnel. So…

I was searching on the net for a Qt Object Explorer that would help me to understand large software and that would help others to understand software that I write. But I could not find one, also it turns out that quite a few people are searching for one. A brief search in Qt’s mailing…
