3-D Cursors Sculpt at Siggraph
The Hyve-3D system and 3-D cursor will be available via the University of Montreal's technology commercialization unit.

University of Montreal researchers demonstrated a system at the SIGGRAPH 2015 conference that uses a tablet to control a three-dimensional (3-D) cursor that can be used to draw and manipulate objects in 3-D simulations. The technique uses back-and-forth and up-and-down motions of the tablet to move the cursor through a 3-D environment, while also incorporating pinching and other gestures.
The cursor works in conjunction with the Hyve-3D (hybrid virtual environment in 3D) simulator, which also was developed by the University of Montreal team. The immersive images from Hyve-3D are projected onto a 16-foot spherically concave fabric screen, although its simulations also can be interacted with on a two-dimensional screen. Multiple users can use the combination of Hyve-3D and the 3-D cursor to simultaneously sketch, select, edit, and manipulate design elements in the same simulation, either using a shared window or on personal windows. The technology is expected to be used by architectural designers, medical imaging groups, and computer gamers.
"The techniques we're unveiling today involve using a tablet to control the cursor, but as it does not necessarily rely on external tracking of the user's movements, eventually other devices could be used, such as smartphones or watches," says University of Montreal professor Tomas Dorta.
