An Image-based Approach for 3D Embossment Effects
一种基于图像的3D浮雕效果绘制算法

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.
