摘要
论文围绕三维景观系统中的高分辨率输出技术进行了分析与探讨,针对传统输出方法因受帧缓冲大小的限制所存在的不足之处,提出了一种新的行之有效的高分辨率输出方法。其主要思想是对整个三维场景采用“分而绘之”的方法,通过动态调整透视投影参数来达到不同区域场景的高分辨率独立绘制,并最终获得满足要求且无缝拼接的三维渲染效果图。
In this paper,the high resolution output technique is discussed and a new effective output method is obtained to be a solution to defects of traditional methods which are limited by the size of frame buffer.The main idea is decomposing the whole3D scene and drawing by grid.By adjusting the perspective projection parameters dynamically,it can get a seamless and high resolution3D scene drawing.
