A while before all the hype of tablet PCs and iPads, some great minds over at the Department of Computer Science of Toronto University developed a system giving the ability to “sketch” in 3D space while using a tablet-type device. ILoveSketch” is a 3D curve sketching system that brings the benefits of drawing like pen on paper, while automatically creating a concept 3D curve model. It’s a really clever system integrating traditional sketching techniques and user interaction with a 3D model in novel ways.

“I Love Sketch” could become a great asset to industrial designers to rapidly draw up 3D concepts designs, though you can easily see it being used for conceptualising architectural forms and complex designs before moving onto CAD or BIM apps. As
Google Sketchup revolutionised quick + easy modelling to a point where nearly anyone can draw in 3D, this kind of system could do the same with virtual sketching methods as sketching is more natural than using a mouse and requires less training to get the hang of. This isn’t just t two-dimensional sketching, but an evolution of a kind using nurb-based geometry to create freeform shapes via curves of high precision and great ease. ILoveSketch takes advantage of multi-stroke sketch techniques and gesture-based functions to create groups of these curves while drawing with a Stylus-type pen.

The video above demonstrates what ILoveSketch is all about while taking the viewer through the basic techniques used to create an airplane model in 3D without needing any kind of command or specific buttons.The environment is easy to navigate - zooming, panning, rotating, etc. are intuitive, while easily switching between the different sketching techniques.

If this sort of system could become integrated somehow into a powerful multi-touch surface like the iPad together with something like the
Pogo Sketch, it could change the designers workflow dramatically and even be a major step up from the previously discussed CAD or BIM app. Hopefully in the near future we’ll see what these guys can come up with - one thing’s for sure, cadmonkeys of the world are itching to see in the next few months what’s boiling in the iPad pot.
