一种基于图像的3D浮雕效果绘制算法

An Image-based Approach for 3D Embossment Effects

提出了直接从2D的绘画图像中得到浮雕效果的方法。将图像看成2D网格,图像上的颜色作为加在该网格上的高度场,图像上的每个点对应3D模型中的一个采样点,进而进行三角化和绘制。还引入法向图,通过形象地调节几张法向的图像修改绘制效果。

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.
