Hi Everyone,

If you like music or 3d printing, you should come to this talk.

A colleague of mine from Autodesk will be giving a talk during the Graphics group meeting tomorrow at 2pm. He does very interesting work that mixes real-time interaction, simulation, and fabrication to create very cool novel objects – that actually work.

Check out a previous project to design arbitrary airplanes (that actually fly): https://www.youtube.com/watch?v=-KJUVJAUY8o

Hey everyone, Sorry for the late notice, but Nobuyuki's back to give another great talk and I'm hoping plenty of you will be able to attend! This time he'll be talking about some of his recent work on designing 3d-printed wind instruments! The talk will be held in the graphics seminar room (BA5187). I hope to see everyone there! Attached are some images of his results as a preview for his talk :). -Michael

Title: Printone: Interactive Free-form Design of Print-wind Instruments

Abstract: This paper presents an interactive design interface for three dimensional free-form musical wind instruments. The sound of a wind instrument is governed by the acoustic resonance as a result  of complicated interactions of sound waves and internal geometries of the instrument. Thus, creating an original free-form wind instrument by manual methods is a very challenging problem. Our interface provides interactive sound simulation feedback as the user edits, allowing exploration of original wind instrument designs. Sound simulation of a three dimensional wind musical instrument is known to be very computationally expensive. To overcome this problem, we present a novel fast resonance frequency prediction method based on the boundary element method. Specifically, we formulate the resonance problem as an minimum eigenvalue problem of a nonlinear matrix. Furthermore, we can efficiently compute an approximate resonance frequency using a new technique based on a generalized eigenvalue problem. The designed wind instrument can be fabricated using a 3D printer, thus we call this new kind of musical instruments “print-wind instruments” in association with woodwind  instruments. We demonstrate our approach with examples of unconventional functional wind instruments. ___________________________________________ graphics mailing list graphics@dgp.toronto.edu https://www.dgp.toronto.edu/cgi-bin/mailman/listinfo/graphics
