摘 要

随着3D技术的不断发展与创新，三维动画的表现艺术也有了空前提高。当下的影片不仅仅追求故事的情节，也在画面的质量效果上不断的提高探索。通过刺激观众的眼球，让观众的视觉效果的到满足，已经成为众多影片制作者的意义追求所在。

这其中灯光有着不可替代的作用和价值，光在生活中有着至关重要的作用，但随着社会的发展，光除了照明的功能外还可以彰显出艺术的气息，在很多的领域都有运用。在三维动画中对光效的要求就非常的高，而且运用的也非常广泛，更是有着至关重要的作用。三维空间内的灯光效果也是参照现实灯光灯光感受为依据的，灯光、物体和动画相结合可以达到一个很好的三维效果。本文将对灯光三维动画中的作用进行研究、分析，来提高对三维动画的整体控制能力。

关键词：灯光、三维场景、氛围、视觉效果

Abstract

With the development and innovation of 3D technology, the performance art of 3d animation has been improved. The current film not only pursue the plot of the story, but also in the pistimulating the audience's eyeball, let the audience's visual effect to the cture quality effect of continuous improvement exploration. By satisfaction, has become the meaning of many film makers to pursue. Light plays an important role in life, but with the development of society, light can not only show the function of lighting, but also show the breath of art, which is used in many fields. In the three-dimensional animation on the light effect requirements are very high, but also very widely used, is of vital importance. The lighting effect in the 3D is also based on the perception of real light, and the combination of light, object and animation can achieve a good 3d effect. This paper will study and analyze the role of lighting 3D animation to improve the overall control ability of 3D animation.

Keywords: lighting, 3D scene, atmosphere, visual effects
