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):

Subject: [graphics] Talk by Nobuyuki Umetani TOMORROW (March 29th 2pm ba5187)
To: graphics@dgp.toronto.edu


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 :).

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.
