Then the color and contrast attenuation models are presented to replace the color term and the contrast term in energy function which will reduce the infection due to illumination.

其次，算法提出颜色衰减模型和对比度衰减模型，改进能量公式中的颜色分量和对比度分量，消除光照变化对于减除结果的影响。

Global illumination is used to render 3d models. The proposed simplification method is tested using largescale point data, and the results verify its effectiveness.

利用全局光照模型实现对三维形体的绘制，并利用大规模点模型对所提出的简化方法进行了试验，试验结果证明了方法的有效性。
