A 3D quick sketch algorithm in virtual reality for concept design in architectural studio

The development of information technologies shows its effects in various design disciplines. Architects and students have been using these technologies for decades. However, traditional manual drawing methods are still frequently used in concept sketching. In this study, a rapid sketch modeling method has been developed in the Virtual Reality (VR) environment to be used in the concept phase of the design for the use in architectural education. Thanks to the visually scripted algorithm, it is now possible to make quick 3D sketches and view them in the concept design phase. In order to develop a solution to the difficulties in transferring two-dimensional sketches to three-dimensional models in amorphous form, the study proposes 3DQSA (3D Quick Sketch Algorithm), a rapid modeling method with hand movements using VR technology in the sketch phase of concept design in an architectural studio. The experiments demonstrate that 3DQSA is beneficial during the concept design phase in architectural education.
