3D游戏场景中镜头眩光特效的研究与实现

Research and Implementation of Lens Flare Effects in 3D Game Scene

摄像机镜头正对光源时产生的眩光现象可以营造真实的光照环境。首先,将Alpha混合技术进行优化,然后对饱和相加混合算法进行优化,最后结合眩光技术的组成与特点实现了3种镜头的眩光效果并将其应用于游戏场景天空体中太阳光的生成,使得动画效果不再单调,更加逼真。该方法简单实用,方便嵌入到现有各种动画系统中。

Through the camera lens facing the light source of glare phenomenon can create a true light illumination. This paper will first alpha blending technology to optimize, next to saturated additive hybrid algorithm is optimized. Finally, combined with the composition and characteristic of glare technology to achieve a three lens flare effect and application in the generation of game sky scene in the light of the sun,and makes the animation effect is no longer monotonous,more re- ahstic. It is worth mentioning that the method {s s^mp[e and practical, and can be easily embedded into the existing anima- tion system.
