文章提出了一种基于球形光线追踪的位移贴图算法。
In this paper, a displacement mapping algorithm based on sphere ray-tracing is introduced.
再在表面利用一个位移贴图为景观增加自然的起伏。
A further displacement map on the surface itself is added for additional natural undulation to the landscape.
主题包括烘烤的综合几何位移贴图，渲染结果，通过正确的AO通道，等等。
Topics include baking displacement maps from combined geometry, rendering the results, correct AO passes, and more.
如果需要一些整体上的特征，也可以在位移贴图完成后使该物体产生一点轻微畸变。
After the displacement mapping is set to stone it is possible to deform objects slightly if there is need for more radical features.
