I used this Christmas as an excuse to get a few things relating to the various software tools I’m writing at the moment.
The C++ Programming Language 4th Edition by Bjarne Stroustrup replaces my well loved, dog-eared 2nd Edition that I’ve had for many years. I haven’t felt like I’ve fully got my head around the new language features of C++ 11 and I enjoy Bjarne’s non-nonsense description of them. He did create C++ after all… It’s probably not a book for the absolute beginner but it’s one that I refer to often, always picking up new tricks or refreshing some of the less used techniques.
I’ve been working on my new software called Fugio (pictured above) for over a year now and I want to make it support a variety of hardware, so I got a couple of new things to try it with:
The last game controller I had was an ancient Logitech one that was quite nice until batteries kept leaking inside of it. I upgraded to the Xbox 360 controller for Windows and wrote a node for Fugio to read all the various parameters from it. It’s very simple to do with the Microsoft XInput API, although obviously Windows only.
While I love my original Korg nanoKontrol for MIDI control, I felt like I needed something a bit more ‘hitty’ so I plumbed for the Akai MPD18 Compact Pad Controller so I can experiment with triggering off events within Fugio. I’ve got most of the controls mapped in using PortMidi and am just sorting out a small bug in the MIDI clock code so I’ll be able to use the note repeat controls on the MPD18 in sync with the Fugio playback.
And while not related to software development and much more related to the process of creating visuals and art, I’m very much enjoying reading Sculpting in Time: Reflections on the Cinema by the late, great film director Andrei Tarkovsky. It’s a no-holds-barred personal rant about his views and experiences on making films and is full of inciteful comments that are giving me much food for thought.
And with that Amazon Affiliate link laiden post done, I will wish you all a very happy New Year and am looking forward to bringing you some new exciting tools in 2015.
It’s been a while since my last update, though not from lack of action, rather I’ve been struggling with my latest project for a the past few months and I felt it’s time to pull back the curtain a bit and show what I’ve been working on.
My original design for the Timeline software was a nice open-ended sequencer that could manipulate all manner of types of data from single values (for MIDI or OSC control of parameters) to colours, audio, and even video, combined with a flexible (possibly too flexible) control over how each track played back with repeating sections and random markers, and all manner of tricks that I was getting really excited about using.
I’d spent almost a year working on it and had a pretty nice media playback engine, and everything seemed to be heading towards a 1.0 release back in June 2014 but then I hit a wall, which I have to say is pretty rare for me in my software development experience as I’ve always had a clear idea about what the role and function of each system I’m developing has been.
The problem was the growing complexity of visually managing the relationship between the different tracks of data and how these related to other applications and devices through the various input and output interfaces. I was also toying with the idea of being able to apply real-time effects to video and audio (also data) and these did not comfortably fit into the design I had come up with.
I’ve also slowly been working on another application called PatchBox that uses a node based interface to visually build connections between blocks of functionality, so I took a deep breath and ripped the code apart and put in a new interface:
The node interface went some way towards solving the problem of presenting the relationship between tracks and devices, but there was a major problem, in that the core code for the node system (it’s actually the code that drives several of my art installations such as Shadows of Light) was rather incompatible with the core code of the Timeline application, and a hard decision had to be made:
Release Timeline and PatchBox separately and fix the interface issue over time.
Combine the two applications, which would require taking a massive step back equivalent to months of development time.
Not an easy one to make, compounded by the fact that as a freelance artist, until I get a product on sale, I’m basically paying for all the development time out of my own pocket so the latter option was not to be taken lightly.
After a couple of weeks of chin stroking, frantic diagrams scratched in notebooks, thinking about what configuration would be most commercially viable, and false starts, I came to a final thought:
“Make the tool that you need for your art”
It’s not that I don’t want it to be a useful tool that other people will want to use and buy at some point (that would be lovely) but I’m not a software design company, and this is primarily an “art platform” for my own work so I have to listen to what feels right to me.
So, I chose the latter (of course) and I’ve been working on it at least a few hours a day, pretty much every day for the past few months. The screenshot at the top of this post is the latest showing a colour timeline track feeding into an OpenGL shader.
There is still much to be done and it’s pretty gruelling at times as I’m having to go over old ground repeatedly, but I feel like it’s heading in the right direction, and I’m already creating new artworks using it that wouldn’t have previously been possible.
Realistically a 1.0 release isn’t now going to happen until 2015, though with a long solo project like this it is easy to find yourself on the long slide into a quiet madness of complexity and introspection so I’m planning more regular updates to at least keep my progress in check by “real people”. To this end, if you have any comments, questions, or general messages of encouragement, I’d be happy to hear them.
fugScreenCapture is a new utility that allows you to capture all or part the window of an application running on your computer, and send it as a video stream to other applications that support the bigfug video streaming system.
NOTE: fugScreenCapture is currently in development, which means:
It’s currently only available for Windows – OSX and Linux versions are planned
It uses only the most basic window capture method, so:
The speed of capture might not be that fast on your system
It might not be able to capture all windows
You can download a demo version to try the capture performance out on your system and see if it meets your requirements.
Laurent Smadja and Scott Baker informed me of a couple of problems with fugFeedbackGL, namely that alpha wasn’t working quite as expected, and that on some Apple computers, the resulting image was stretched incorrectly.
There is now an 1.1 update for fugFeedbackGL for both Windows and Apple OSX that fixes these issues.
