基于图像的渲染技术(ibr)就是为了使得两者达到平衡，IBR能够高效的实现高质量画面效果，文中我们提出了一种采用IBR技术来渲染大规模森林场景的方法。
Image based rendering methodology (IBR) can give a good balance between them. In this paper, we will have a sample about how to use IBR to rendering a large-scaled forest scene.
基于图像的绘制技术不同于对已知场景建立的3d计算机图形，它是利用输入的图片进行渲染。
Unlike traditional 3d computer graphics in which 3d geometry of the scene is known, image-based rendering techniques render novel views directly from input images.
经过仔细的测试以及权衡，我决定抛弃EWA过滤技术转向GPU超采样的方式对基于点渲染的图像进行过滤。
During careful benchmark and balancing, I decide to abandon the EWA filter, turn to use GPU supersampling filter method in offline rendering, did as the same as NVIDIA Gelato.
