A Study on a Drawing Tool of a Spatial Drawing Application in Virtual Reality

Abstract

A system for spatial drawing must have a display device that shows stereoscopic images to the user, a controller serving as a brush for drawing, and a function that creates a line and a curved surface and visualizes the virtual space. Herein, a software framework was designed for spatial drawing by analyzing the functions for spatial drawing applications in a virtual environment based on existing studies and produced a virtual reality spatial drawing application with virtual drawing tools. The application employed a traditional painting metaphor. Furthermore, a brush module and a palette module were designed for the spatial drawing interface and linked to the line and surface generator modules to change drawing attributes, e.g., color and texture.

Comparison of Characteristics of 3D Laser Scanner for Construction of Indoor Geospatial Information

“…Recently, According to a report by the US Environmental Protection Agency, it is known that on average, about 80% of the total life is done indoors [1,2]. Recently, the design and operation of buildings and various ICT technologies have developed and the interior space has become larger and more complex [3,4]. As the various activities such as conventions, shopping and entertainment are carried out without moving outdoors, the cost of living in the indoor space is gradually increasing.…”
