Functy 0.35 now available

  • Posted on May 18, 2015 at 2:08 am

Version 0.35 of Functy is now available for download. Variants are available for Windows, Linux and as source code. There’s also now a Launchpad PPA for installing nightly builds on Ubuntu.

The main improvement to this new version is the ability to export models as OpenVDB voxel clouds. OpenVDB is the award-winning 3D sparse volumetric data library developed by Ken Museth at DreamWorks Animation, and used in a bundle of movies including Puss in Boots, Madagascar 3, How to Train Your Dragon and Turbo (I’m really gunning for success by association here, in case you hadn’t noticed!).

Functy 0.33 now available

  • Posted on November 2, 2014 at 9:03 pm

This latest version has two main new features. First it allows animations to be exported as a series of PNG frames. Second you can also now export in Simple Voxels (SVX) format. This is a neat new format that represents a model as a volume rather than a surface as would normally be the case with STL or PLY files. Functy is ideally set up for this, since the objects are mathematically defined anyway. SVX files are also ideally suited to 3D printing, which ultimately is working with 3D volumes too.

Even though it’s new, Shapeways already allow upload of models in SVX format, and you can see an example - my first attempt - on the Shapeways site.

There have been some more minor improvements too. For the first time ever, Functy now has an About window. Only a small thing, but long overdue. It’s been on the back-burner for a while, since until recently Ubuntu’s version of Glade crashed when creating dialogues. Ironically I didn’t end up including it in the gtk-builder file anyway. Never mind. There’s also a new Progress window to make long exports bearable. SVX export can take some time, so this became a necessity. But it also helps with exporting of animations too, since these can also take a surprising length of time when every frame has to be generated as a separate file.

Please get yourself a copy and try out the new features. As with every release of Functy since the dawn of time, this is still a beta version, so please bear this in mind and let me know if things go wrong.

As always, the binary and source is available direct from Sourceforge or via the downloads page.

Functy version 0.32 now available

  • Posted on October 4, 2014 at 7:38 pm

It’s not been long (just under a week) since the last Functy release, but the latest changes are suitably discreet to allow this minor update straight away.

The latest version now allows export in STL format, to complement the existing PLY export capabilities. Scenes can either be exported as static models, or with animation as a sequence of STL files for each frame.

In addition, there’s also been a bit of bugfixing too. One particularly nasty bug caused PLY export to fail for some scenes when the program was running on Windows (it was always fine on Linux). I’m hoping the bugfixes will resolve this problem. Please let me know how you find it, especially if it still causes problems.

As always, the binary and source is available direct from Sourceforge or via the downloads page.

Functy 0.24 released

  • Posted on May 29, 2012 at 7:26 pm

I’m very pleased to announce the release of Functy version 0.24, which can now be obtained from the downloads page.

The main changes from the previous version are the following.

  • Addition of the new curve function type. This complements the existing Cartesian and spherical functions by allowing parametric curves to be defined with cross-sections based on cylindrical co-ordinates.
  • All function types can now be rendered either using the CPU (as before) or entirely using the GPU.
  • GPU rendering provides per-pixel lighting calculated using the derived normal function (rather than using interpolated normals as used by most per-pixel algorithms).
  • Available for Windows and Linux, and also as a new ARM Debian version for use with the Raspberry Pi.

Functy is still very much a work-in-progress, and won’t be entirely bug-free, so if you stumble across a problem or have any difficulty with it please let me know.


Raspberry Pi Functy Package

  • Posted on May 27, 2012 at 10:34 pm

Having spent far too much of my weekend playing around with a Raspberry Pi, I’m pleased to say that this has at least resulted in a nice new ARM Debian package of Functy to run on the tiny credit-card-sized computer.

Even though the 3D graphics are a bit slow right now, I’m thoroughly impressed that the Raspberry Pi was happy to build and run Functy with practically no modification. I wasn’t expecting that!

There are more updates to Functy in the pipeline, but in the meantime, the new Raspberry Pi build (which even contains functionality not yet found in the other versions) can be downloaded from the downloads page.

Functy deb and rpm packages

  • Posted on June 28, 2009 at 5:45 pm

Binary packages of Functy 0.22 are now available in .deb and .rpm format. I threw these together this weekend without having a great deal of understanding of what I was doing, so it’s possible they’re just a mess and won’t work at all.

As I use Ubuntu I’m not able to properly test the rpm package. What’s more some corrupt files on my system are preventing apt from working properly, so I’m not even able to fully test the deb package either. It’s all a bit rubbish really, but they’re available anyway as I’m sure they’ll be a better place to start for many people. Fingers crossed they’ll work as expected, but if not I assume I’ll find out soon enough!

You can get the new packages from the SourceForge projects page page, or click on the downloads link in the sidebar.

Functy version 0.22 (beta) released

  • Posted on June 25, 2009 at 12:56 am

I’m pleased to say that version 0.22 of Functy is now ready for release. Although this version does fix some bugs, the main improvement is that there’s now an automatic installer for Windows users.

Functy version 0.21 (beta) released

  • Posted on June 15, 2009 at 7:16 pm

Oops. After releasing version 0.2 I immediately found a couple of bugs! So version 0.21 is now available as a minor bug-fix release over 0.2.

Functy version 0.2 (beta) released

  • Posted on June 15, 2009 at 12:42 am

Functy is a 3D graph drawing package. The emphasis for the application is to allow Cartesian and spherical functions to be plotted and altered quickly and easily. This immediacy and the vivid results are intended to promote fun exploration of 3D functions. Functy can be built for GNU/Linux or Windows.

This 0.2 release is still beta, but has a number of improvements over 0.1 including:

  • An improved user interface.
  • New functions that can be used, such as cosh, atan, sec, exp, abs etc.
  • Spherical coordinate plotting of functions.
  • Various smaller bug fixes and changes.

Some kind of Functy release

  • Posted on April 26, 2009 at 10:17 pm

Well, after pretty much an entire day of shunting files around the network using more protocols than the EU, I can finally say that there’s a Functy release to show for it.

This is version 0.1, which means it’s a bit brittle and the paint is still drying. It also comes flatpacked, so you’ll have to build it yourself. But if you can get past all of that, it does just about work.

The packages can be downloaded at
