libnifalcon v1.0.1 released, np nifalcon v1.5 released

2009-09-20T00:00:00-07:00

Busy weekend for the libnifalcon team (all one of me)!

First off, libnifalcon v1.0.1 is out. This is mostly bugfixes for using multiple falcons on top of the libusb core.

Change List:

Fixed bug with connecting to/using multiple falcons using libusb communications
Added adjusted geometry measurements by Niall Begley
Fixed bug with reloading firmware through reused FalconDevice object
Added ability to test multiple falcons to findfalcons
Added findfalcons_multi example to test multiple falcons with simultanious access

Files are available at

https://sourceforge.net/projects/libnifalcon/files/libnifalcon/1.0.1/

Next up, np_nifalcon, the external for Max/MSP and PureData, has been updated to version 1.5. I basically rewrote the external, it’s much more stable now, as well as providing more management options for users.

Source and some binary packages are available at

Finally, to show off some of what’s been going on with people using libnifalcon, here’s a video of the library being used with HAPI, Blender Game Engine and Bullet

libnifalcon v1.0 released

2009-09-06T00:00:00-07:00

After 2 years of work, libnifalcon v1.0 has been released! Here’s the changelog since our last release:

Upgraded build system support to work with new Compily Buildd system
Integrated Alastair Barrow’s new kinematics core based on the RL Stamper paper (replacing Kevin Ouellet’s implementation)
Added SWIG support with python and java builds and examples
Removed libftdi support since libusb 1.0 works on all platforms and libftdi is the only library using non-polling updates
Defaulted comm libraries in FalconDevice (ftd2xx on windows, libusb-1.0 everywhere else).
Restored falconmouse example, since building is more stable
Documented a whole bunch. Doxygen now puts out something resembling a manual.

The new version is available at

https://sourceforge.net/projects/libnifalcon/files/libnifalcon/1.0/libnifalcon-1.0.tar.gz/download

The documentation for v1.0 can be accessed at

http://docs.nonpolynomial.com/libnifalcon/release/doxygen/html/

I’m hoping to have new versions of the Pd/Max externals built using v1 of the library out ASAP, and will post here once that’s done. I’m also planning on platform specific releases of python and java libraries, as well as any other language bindings anyone might be interested in.

Not really sure what’s in store for the next version yet, as v1 covered quite a bit of things I was planning for post-v1 development. Definitely planning on starting grip hacking soon.

libnifalcon support in H3D

2009-08-08T00:00:00-07:00

As of commit 473 to the HAPI repository (which actually happened almost two months ago), libnifalcon support is officially in the H3D Haptics Engine! This means you can now use the falcon in H3D on OS X or Linux. I’ve tested it on OS X, and it seems to work great so far.

You can find out more info or pick up the source yourself (you’ll need to do a checkout of the svn repo) at

H3D API Integration for libnifalcon

2009-05-25T00:00:00-07:00

We’ve talked about H3D integration quite a bit on the libnifalcon-devel mailing list, but it now appears that it’s actually going to happen. There are a couple of projects currently in the works:

The development team at polydimensions.de has been working on a libnifalcon patch for H3D, along with their efforts to integrate the Bullet Physics Engine into the H3D framework. This should be integrating with the H3D development branch soon.
The developer of the Volume Haptics Toolkit has submitted a patch to HAPI that allows for libnifalcon support (note: you will need an account on the H3D website to access this page).

So, hopefully libnifalcon will be supported in H3D soon, one way or another.

New libnifalcon project website

2009-05-24T00:00:00-07:00

Decided to try building a new project website for libnifalcon, using the jekyll framework provided as a feature on github repositories. Start expecting project updates here.
