| Research Abstract |
When this research started, we had already established a freehand sketch-based modeling interface Blue Grotto that utilizes a virtual reality (VR) environment The aim of this research is to establish a mechanism that makes Blue Grotto serve as a font end processor (EP). As a result of the research, we realized Blue Grotto FEP that provides midair sketch recognition service for 3D CAD applications, and we confirmed that the combinations of Blue Grotto FEP and existing CAD, systems work well as practical sketch--based CAD applications.
Step 1
We introduced a skinning operation into Blue Grotto and established a new user interface with which a user can input multiple profiles by freehand drawing.
Step 2
We designed a versatile communication protocol between Blur Grotto and practical CAD applications. Then, we confirmed that the protocol realizes an automatic synchronizing mechanism in the combinations of Blue Grotto and the CAD applications.
Step 3
We reconstructed visual feedback systems of Blue Grotto and improved the usability of the interface.
Step 4
We implemented the new user interface and the communication protocol by using C++ and OpenGL and materialized Blue Grotto FEP.
Step 5
We materialized interface modules for two kinds of practical CAD systems (which are AutoCAD and Shade) based on the versatile communication protocol.
Step 6
Through some experimental trials, we confirmed that the proposed versatile communication mechanism made identical Blue Grotto FEP work in cooperation with different practical CAD applications.
Step 7
Through some practical drawing experiments, we showed that the combinations of Blue Grotto FEP and practical CAD applications can work as practical sketch based CAD systems, with which a user can freely switch between sketch operations of Blue Grotto FEP and command operations of the practical CAD systems.
