A study on AR 3D objects shading method using electronic compass sensor

Abstract

More effective communications can be offered to users by applying NPR (Non-Photorealistic Rendering) methods to 3D graphics. Thus, there has been much research on how to apply NPR to mobile contents. However, previous studies only propose cartoon rendering for pre-treatment with no consideration for directions of light in the surrounding environment. In this study, therefore, ECS(Electronic Compass Sensor) is applied to AR 3D objects shading in order to define directions of light as per time slots for assimilation with the surrounding environment. © 2010 Springer-Verlag.
