BlueGrotto is a system that makes freehand sketching of solid primitive geometrical shapes possible just by sketching in the air. BlueGrotto also, like SKIT, uses FSCI as a sketch identification engine (Who would like to see the vedio first, please go here
It is possible to draw precise solid shapes using conventional CAD. But for this, the user has to repeat the process of switching between planes and drawing, while also heavily depending on indirect menu operations. Because of this, it is not easy to advance the drawing process in a direct sense of drawing in 3 dimensional space. Recently efforts are done to achieve direct drawing by using pen-tablets and Virtual Reality environments. But as there are no serious sketch identification involved, problems have arisen such as no uniform methology in the input of solids and limits in free form solid generation. For these reasons, we considered that a non-conventional method is needed to achieve a "Multipurpose sketch identification interface for input of various geometrical solid objects"
Therefore in this laboratory, we are developing BlueGrotto by realizing full scale identification of sketch by FSCI in VR environment so that the input of various geometrical solid objects is possible by uniformed sketch drawing.
Moreover, developing of BlueGrottoFET that is a system that turns BlueGrotto into a 3D sketch input front-end processor is also being carried on. This provides direct 3D sketch input abilities of BlueGrotto as a service to existing CAD systems. Due to the development of BlueGrottoFEP, we intend to realize an environment that enables the user to use direct sketch input of BlueGrotto in combination with abundant editing commands of CAD.
