贴图

Resize and move your texture into a suitable place and then desaturate it.Change the blending mode of your texture layer to overlay.

重新调整尺寸然后把你贴图移动到适合位置覆盖背景。

Meanwhile, the scenes of rain, snow, fire flame and explosion are simulated livingly by means of particle system and dynamic texture mapping.

同时，利用粒子系统和动贴图方法实现了雨、雪、火焰和爆炸效果模拟。

As mentioned above in the directional lights section, the rendering of shadows for directional lights is an approximation that allows us to use a single render to cover a largeish area with shadows.

你也可以用着色语言作为技术实现基础来处阴影投射和接材质来实现更复杂阴影算法，比如实现支持自投影深度阴影贴图。
