An Image-based Approach for 3D Embossment Effects
Xindong Ye, Zhangye Wang, Tang Feng · Jisuanji yingyong yanjiu · 2005
Proposes a simple algorithm to get 3D embossment effect from a single image. We regard the 2D image space as a grid and it's grey-level as the height field on the grid, using the original image, together with a normal map, which helps to control the final rendering effects, fairly good rendering results can be obtained.
