As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I've been developing apps and frameworks for several years (since I was in college). Pre-Vuo projects include Kineme Quartz Composer plugins, iOS apps for education, an app that analyzes photographs of tomato slices, and software to help people with disabilities use talking keyboards.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
Hey, my Vuo peeps. Since the Vuo 1.2.6 release in June, we’ve published three new and remarkable community spotlights. Also we have a tip to share about Vuo’s keyboard shortcuts.
Community spotlight: Circus Family celebrates rainwater and Sinterklaas
Circus Family have turned to Vuo many times in their audiovisual design work, including The Rain Project and Hema Sintersizer. The Rain Project, a collaboration with advertising agency J. Walter Thompson, was a short film about “the never-ending source of Spa mineral water”. In a forest, they built an installation in which rain sensors trigger sound, light, and projections. Hema Sintersizer was a humongous music-making machine made of toys for the Sinterklaas holiday. The agency XXS commissioned Circus Family to create the Sintersizer for Hema’s flagship department store in Amsterdam.
Community spotlight: Lori Hepner and Kendra Ross light-painting women's experiences
The visual art of Lori Hepner and the music of Kendra Ross combined in Intersection*ology, a performance that “explores, adapts, morphs, rejoices and revolts in the many ways women are perceived”. A key part of the performance was lightpainting, a process that Lori adapted from her work in long-exposure photography to a real-time performance setting. Kendra and Lori wore LED strips, a camera captured their movements, and Vuo turned the live video into trails of color. They’ve given two performances in Pittsburgh, USA, and plan to do more.
Community spotlight: Dancers with disabilities paint with body movements at IMPACT Theatre
IMPACT Theatre have used Vuo in their mission “to promote a positive image of disability and to develop communication and self-confidence, though participation in performing and creative arts”. They recently used Vuo in a performance called Hyper in which dancers made virtual paintings with their body movements using skeletal tracking. IMPACT Theatre will be using Vuo again in a puppet show on August 5 in Perivale, UK.
We also love sharing what people have done with Vuo! Whether your work is a professional exhibition or just something you did for fun, it might make a great community spotlight. And hey, maybe it’ll spark someone else’s idea for their next Vuo project.
Tip: Keyboard shortcuts
Did you know that you can…
duplicate a cable by holding down the option key while dragging from an input port?
make a cable event-only by holding down the shift key while dragging the cable?
make the canvas slightly transparent with ⌘2 and very transparent with ⌘3?
move the canvas viewport by holding down the spacebar and dragging?
That sounds like a different issue. Since the nodes cause CPU load to go down and events to be dropped, the bottleneck now is probably the GPU.
You could try the image filters one at a time to see which one is affecting performance the most. I'd guess the Blur with radius 16. If so, you could use Resize Image to reduce the amount of work that Blur has to do.
We're working on some usability improvements for generic ports in Vuo 1.3, particularly the process involved in changing from one data type to another. I think they might solve your problem, @Alastair. I'm tabling this feature request, and we can reevaluate it if needed after the improvements.
