Oo, regarding the integrated fiducials, I just had an idea of how to do that really speedily without needing the complexity of multi-color 3D printing — you could design the shape with a "physical fiducial" on each face, like raised Braille-like dots or an embossed QR/Apriltag or whatever, and then you could very rapidly paint that portion of each face black by simply "stamping" it on an ink bed and letting it dry. > On Jun 9, 2023, at 12:51 PM, Luke Iannini <****************> wrote: > > Yeah I love that idea!! We've been talking about ways to get as quickly as possible to tangible representations, like a workflow where you 3D print intermediate designs (maybe out of some custom lego-like pieces with integrated fiducials of some kind), make modifications in a hybrid tangible/projected space, reprint blocks/diffs where needed, etc., and it would be magical to mount the actual components on linear actuators like this for the ability to seamlessly switch between direct manipulation and computerized/parametric manipulation (which is exactly what "flying faders" on high-end mixers are great examples of!) > >> On Jun 7, 2023, at 11:46 PM, Bret Victor <****************> wrote: >> >> Very cool! >> >> It made me think of, for showing z-depth, you could get a motorized fader and prop it up vertically on the table, and hook it up to a microcontroller or raspberry pi.
