摘要
近年来，随着计算机技术的飞速发展，多媒体的表现形式也越来越多。全景播放技术是指将全景序列图逐帧正确地渲染到二维的显示器上，实现任意方向和角度观赏的360度全景景观的效果。为了正确地渲染全景图，采用等距圆柱投影法，经由一系列的坐标变换，最后转换为正确的三维坐标。为了提高播放帧率，在帧渲染的过程中采用缓冲区对象的技术和纹理替换的技术。实验结果表明，该方法使全景图得到正确的渲染，有效地提高播放的帧率。
Abstract
In recent years, with the rapid development of computer technology, multimedia also has more forms. Panoramic display technology refers to the sequence diagram frame by frame rendering on two-dimensional display correctly, and implements the effect that you can view the 360 degree panoramic from any direction and angle. In order to correctly render panorama, uses cylindrical equidistant projection method, through a series of coordinate transformation, and finally converted to the correct three-dimensional coordinates. To improve the broadcast frame rate, in the process of rendering, uses the buffer object technology and texture substitution technology. The experimental results show that the method makes panorama properly rendering, and effectively improves the play of the frame rate.ate.
