Cím:	Embedding QR code onto triangulated meshes / György Papp, Miklós Hoffmann, Ildikó Papp
Dátum:	2020
Megjegyzések:	The QR code is widely used to provide easily accessible information to anyone with a smartphone, and since these devices play a significant role in our everyday life, a QR code can be read by most people. However, significant deformation can make it challenging to decode a printed QR code. In order to avoid deformation, the printed label should be affixed on a developable surface patch of a 3D model. In the work of Kikuchi et al. and Peng et al., the QR code is embedded onto surfaces to give more freedom in providing additional information. In the first work, the QR code is engraved onto B-spline CAD models, while in the second one, it is embedded code onto general meshes and optimizes its dark modules and minimizes their carving depth to increase the engraved QR code readability. In this paper, we introduce a method to embed a QR code onto any area of general meshes without using subdivision on the mesh. Besides, we propose a method to determine the largest size of the QR code automatically for a user-selected position. Also, our method can find better direction to carve the QR code and achieve a larger size for a user given point in even on highly curved areas. Additionally, we introduce a solution to speed up finding the carving depth for embedding the QR code. Our proposed method uses the Horizon-Based Ambient Occlusion for calculating the shadow in the engraved areas with the help of the GPU.
