This simple tutorial shows how to model a headset in Rhinoceros using T-Splines plugin.
T-Splines model creation from T-Splines on Vimeo.
This design of a headphone illustrates the speed with which you can edit and manipulate surfaces with T-Splines.
The commands used, such as deleting faces, extruding edges, filling holes, and extruding faces are popular techniques used in the animation industry for their speed. T-Splines brings these commands into industrial design for the first time, with one critical improvement. With T-Splines, you can add detail to a model, and the surface doesn’t change or warp until you move the control points, as is done to add the ridge details to the top of the headphones.
